Different types of communication technology in aviation

Different types of communication technology in aviation

The communication systems used in aviation have grown alongside the industry. What was once a series of hand signals and rudder manoeuvres has evolved into an advanced communications system that uses a wide variety of software and hardware to communicate with pilots and air traffic controllers.


Originally, aircraft communications used analogue voice through either very high frequency (VHF) or high frequency (HF) radio wavebands. By the 1980s the aviation industry had moved on to digital, data-driven communications. Aviation management hasn’t looked back since then and has incorporated a plethora of digital communications technologies to better regulate air traffic.


In this article, we’re going to discuss three types of communication used in aviation – VCCS, legal recorder systems and AMHS.




VCCS is an abbreviation of voice communication control system. It is an electronic communications system that is used to control voice communication between air traffic control and the pilot in charge of the aircraft. This system provides a blend of different communication processes including audio devices, radio and telephone switching units and operation controller units. These devices are all core components of modern air traffic management operations.


VCCS is computer-aided and allows for responsive communication from the ground to the air which improved how air traffic management systems work. The VCCS features an intuitive interface that is easy to use mid-flight and allows for phone calls and audio recordings. The VCCS has been incredibly useful for the aviation industry as well as emergency services, the coast guard and other forms of traffic control.


Compliance and legal recorder systems


The aviation industry is heavily regulated, and with good reason. Regulations into how the aviation industry functions ensure optimal safety and security for passengers, pilots and the industry as a whole. There are a number of communication systems that are used to ensure that the aviation industry is compliant with the law and to provide additional safety. One of the most common is radar, which is used to help navigate aircraft during inclement weather.


Air traffic radar is used across the industry as a way to detect and track aircraft as well as help them through weather patterns that provide poor visibility. There are three types of radar used by the industry, which include:


  • Radar control service: used in a controlled airspace
  • Radar advisory service: used in an advisory airspace
  • Radar information service: used when aircraft operate outside controlled or advisory airspace


There are other communication tools used in the industry for compliance and legal reasons. The cockpit voice recorder is a device used to record the entire audio environment during a flight. It records audio from the flight deck and stores the recordings and audio signals of the pilot headsets securely in the event of an accident.


Message handling and aeronautical information systems


Communication between aircraft and aeronautical fixed stations is also important for contemporary flight and it uses the Aeronautical Fixed Telecommunications Network (AFTN) to do this. There are two types of AFTN – AFTN communication centres and AFTN stations. AFTN communication centres relay AFTN messages to and from other AFTN stations. If there is an air traffic service available, it is probably serviced by an AFTN station.


The aviation industry uses the aeronautical message handling system to perform all ground-to-ground communications. This helps with creating flight plans and relaying meteorological data. These newer AMHS-based solutions are being rolled out to replace the previous AFTN systems.

Extra low voltage and low current systems

Extra low voltage and low current systems

Extra-low voltage and low current systems are crucial to the successful running of airports. As airports throughout the world become modernised, they’re increasingly reliant on complex electrical installations. However, safety is vital when it comes to the electrical installation at an airport – the electrical supply cannot interfere with the operations of aircraft and also needs to limit harm to the environment. So how do airports meet the unique needs of their users? The answer is in extra-low voltage and low current systems. Let’s consider how these systems are used in the modern airport.



What are extra low voltage and low current systems?


Extra-low voltage and low current systems can describe a vast range of electrical systems in the airport. The terms “extra-low voltage” and “low current” are frequently used interchangeably. They refer to systems that function using an extra-low voltage. You’ll typically find these electrical systems in areas where electricity could be hazardous, hence why they’re common in airports. These systems have a wide range of applications in the airport.


Car park management systems


Car park management systems (CPMS) are essential at airports, ensuring that vehicles are secure. Many larger airports have sophisticated car parking facilities for both short-term and long-term stays. Effective CPMS ensures that these systems run correctly. Extra-low voltage and low current CPMS can be installed both indoors and outdoors. These energy- and cost-efficient solutions are convenient for a system that is running constantly and don’t interfere with airport operations.


Public signage


Signage is essential to aid and enhance the customer journey through the airport. Airports today typically have a huge range of digital signage, ranging from advertising to flight information and directions. A low current or extra-low voltage digital sign or video wall is safe and environmentally friendly. Offering financial and energy savings, low current digital signage makes a convenient solution in sites where a significant amount of digital signage is required.


Fire safety


Safety is crucial at a densely populated site like an airport. Fire safety is an important consideration and a modern airport should have a reliable fire alarm system. Low current and extra-low voltage fire alarm systems are being used more. Like digital signage, these systems consume less energy and cost less than more traditional set-ups, but they still guarantee improved safety for everyone who uses the airport.


Public address systems


Reliable public address systems are another fundamental part of the customer experience at the airport. Public Address & Voice Alarm Systems (PA/VA) enhance security and provide vital information to airport users. PA/VA systems are in use almost constantly at airports, making low extra-low voltage and low current systems a smart choice for reducing costs and energy consumption whilst still providing a reliable service.


Extra low voltage and low current systems at airports


It’s evident that extra-low voltage and low current systems have a myriad of applications in the airport environment. Offering reliable safety and security measures as well as supporting communication and enhancing the customer experience, extra-low voltage and low current systems are fundamental to the modernisation of airports, without affecting airport operations, damaging the environment, or generating excessive operating costs.

Airport Navigation

Airport navigation: What guides the planes we rely on?

The earliest navigators used the path of the sun while their sons charted the stars. Navigation technology nowadays is somewhat less romantic, but even more important than ever before. Read on to learn more about different types of navigation technology, the importance of getting to the right place at the right time and the role Bayanat Engineering plays in modern navigation systems.


Instrument Landing Systems


One of the most important parts of a commercial flight is landing in a safe manner. After all, you can get to the target location all you like, but doing so without setting down safely and securely is dangerous. Instrument Landing Systems are essential for this. Also known as ILS, this technology features two radio beams pointing out over the runway and informing pilots of both their height and position. This tool works at short range, providing safe landings for pilots in even the worst visibility conditions.


Non-Directional Beacons


In a world of jargon and advanced terminology, a Non-Directional Beacon (NDB) is exactly what it says on the tin. Non-Directional Beacons emit signals of a certain range in all directions, indicating to planes in the vicinity that there is an airport nearby. This is an excellent tool over significant distances, informing pilots of the presence of potential air traffic and their vicinity to their ultimate destination. Whilst not as specific as an ILS, NDBs provide incredibly useful contextual information about the status of a plane’s location.


Tactical Air Navigation (TACAN)


Also known as TACAN, Tactical Air Navigation is a system that was initially designed and manufactured for military purposes before being transitioned to a more civilian role. TACAN provides the user with a bearing to a specific TACAN station in addition to the distance from the station. These stations are typically airports, informing both parties how close a plane is to its intended destination. Furthermore, combining multiple TACAN readings effectively triangulates the position of the aircraft. This means that keeping track of the specific position of an aircraft is much easier rather than making informed guesses.

SBAS (Satellite Based Navigation Systems)


Satellite-based navigation systems play an integral role in the navigation of planes. Emphasizing civilian aircraft, this is an international network of satellites detecting the locations of aircraft on a consistent basis within a margin of error of just one metre. Information is then conveyed to ground infrastructure in addition to the aircraft itself, providing a comprehensive map of the locations of every single one of the commercial aircraft in the skies at any given moment. This removes the possibility of aircraft colliding and makes handling traffic simpler in the event that tailwinds over the Persian Gulf do not result in early arrival at Hamad International Airport in Qatar, for example.


Bayanat Engineering’s role


Bayanat Engineering plays a significant role in airport navigation systems, developing and manufacturing technology for airports in need. Navigation is a fundamental part of international travel, and lacking these systems is dangerous.

A guide to specialised lighting & signage at airports

A guide to specialised lighting & signage at airports

Having the right tools and equipment at the ready is vital for any airline, and this is true even down to the signs and lights that adorn buildings and runways. Without these helpful fixtures, airports would be at much greater risk from crashes, injuries, and even just inconvenience. Airports need the safety and stability that a mixture of clear signage and specialised lighting can give – they help everyone on the ground and in the air stay safe.


  • Everyone knows where to go


Airports are often a place of sheer chaos, with so many people using them at all hours of the day. These people rely upon the building’s guidance to help them get where they need to go. It also ensures that the airport’s foot traffic is as efficient as possible with fewer busy queues. With clear and consistent signage across the airport, there will be less congestion and disorder.


Good airport signage is also a core part of how pilots reliably land planes – airlines use colour-coded signage to show where drivers and pilots can and cannot take their respective vehicles. This allows everyone to go safely to their destination, from taxiing on the runway and beyond.


  • They allow for flying in the dark


Long-distance flights, especially ones crossing multiple time zones, are likely to either start or end in the dark; this makes good lighting essential for any airport. Airfield ground lights are in different colours to denote their functions and are vital visual aids for pilots – they are what let pilots see where to land when it’s dark. This alone makes them essential, and better lighting naturally makes it easier for the pilot and improves safety across the board.


Apron floodlighting is fundamental to any airport; this illuminates the area where a plane loads passengers, refuels, or undergoes maintenance. The time of day, or even just the weather conditions, can make essential work more difficult – this means every airline needs high-grade apron floodlighting to facilitate these functions. Ultimately, the better the lighting, the easier it is for people to see where they are going and what they need to do.


  • They are easily controllable


There are several measures in place to give airports control over their lighting. For example, Airfield Lighting Control and Monitoring Systems (ALCMS) gives qualified staff members a simple way to turn individual (or groups of) lights on or off wherever necessary. This is a relatively recent innovation – but is still invaluable for monitoring the use and intensity of an airport’s lighting systems on a taxiway, runway, or apron.


Airport lighting also commonly uses photometry to measure the light and ensure it stays at a consistent and safe level – and that technicians can conduct maintenance at a moment’s notice. With lighting an essential component of airport safety, tracking its effectiveness is vital.


Bayanat Engineering can provide the best solutions to help your airport – both passengers and staff will feel much safer with clear signage and lighting.

Surveillance in modern airports, and why it is key

Surveillance in modern airports, and why it is key

In modern airports, many different factors are considered when making people and planes as safe and secure as possible. This includes surveillance, keeping track of both land and sky to protect everyone travelling through major airports such as Hamad International Airport. Read on to learn about some of the fascinating technology used in airport surveillance and how it protects passengers and pilots alike.


Drone Detection Systems


As technology advances year on year, drones become more and more complex, increasing in speed, weight, and technology. All of these issues increase the level of threat drones provide to planes in and around airports. A strong defence against drones begins with Drone Detection Systems. These systems are designed to locate drones in and around the local area, using technology such as radar to find aerial disturbances. Once a drone is detected, take-offs across airports are halted until the issue is resolved, preventing a serious issue such as a collision.


Surface Movement Radars (SMR/GMR)


Whilst dealing with issues in the air, the ground provides similar threats to the security of many modern aircraft. One tool used in solving this problem is Surface Movement Radars, also known as SMRs. These operate in the very same way as a typical radar, firing sound waves along a dictated plane and receiving reflected waves back, ultimately establishing their location. Ground-based security then deals with the threats, whether this comes in the form of protestors, vehicles or even just an airport maintenance vehicle that is lost on its route. Planes are at their most vulnerable on the ground, and protecting them is key.


Runway Debris Monitoring System (RDMS)


Runway Debris Monitoring Systems, also known as RDMS, are integral to an effective airport’s operations. Winds pick up in and around airports, and in the event that the area surrounding an airport is packed, debris gets picked up and put onto the runway. Something as simple as a felled tree can get sucked into an engine and cause incredible amounts of damage to the internal components, an issue that puts lives at risk. Using RDMS effectively means threats are removed from the runway and operations go on as normal.


Runway/Airside Surveillance


Whilst you’ll be well aware of the banks of CCTV inside airports, you may not have heard of CCTV systems in operation on the airside of the airport. This means the side with the runway, and CCTV in these cases is essential. Whilst picking up large objects and vehicles is simple with SMR, the system relatively struggles with small organic shapes such as people. The last thing you want is someone wandering onto a runway and not understanding where they are, as this is a serious risk to the airport, planes and the individual themselves. Airside and runway surveillance assist in finding potential threats to be passed onto security services for removal.

How weather management tech can mitigate the risks of meteorological conditions in the aviation and naval industries

How weather management tech can mitigate the risks of meteorological conditions in the aviation and naval industries

Safety is a top priority in both the aviation and naval sectors, where a single accident can have disastrous results for both physical infrastructure and human life. It’s important, then, that managers and stakeholders involved in both industries take any and all measures to effectively help to reduce the risk of such accidents occurring.


Weather conditions, including both poor weather conditions and unexpected meteorological events, can pose a serious risk to human life when they disrupt the journey of planes and other vessels. Let’s explore some of the weather management tech that’s available to both aviation and naval crews today to help mitigate the risks of extreme meteorological conditions during takeoff, landing, and mid-journey.


Lightning detection systems


Lightning detection systems can offer early warning of lightning and similar meteorological phenomena. Lightning detection systems use ground-based sensors to detect electromagnetic pulses emitted by lightning, which can then be used to give advance warning to pilots and flight crew who may be entering dangerous conditions. These can be paired with Lightning Decision Support Systems to help crew make informed decisions about the impact of lightning activity


Thermodynamic Profilers & Radiometers



A thermodynamic profiler is a device that can be used to measure continuous atmospheric temperature and humidity both at ground level and much higher. This data can then be fed to pilots, flight crew, and air traffic control in real-time, informing high-level decision-making regarding flight paths and optimal routing.


Weather Telemetry Systems


Weather Telemetry Systems are widely used today to ensure the safety of passengers and crew even in the event of unexpected extreme weather conditions. Onboard telemetry systems are used to measure nearby conditions, most notably in the form of expendable dropsondes, which can be dropped from an aircraft to monitor storm conditions and capture local thermodynamic data below.


Wind Profilers


A wind profiler is an important weather detection device that uses radar or sound waves to detect both wind speed and direction at various different heights above ground level. This data is invaluable to air traffic control, who can use it when creating flight paths to ensure that high wind speeds do not pose a risk to aircraft mid-flight. By working with, rather than against, the wind, pilots can both improve safety in-flight and reduce fuel emissions, making aviation a greener industry.


Weather Decision Support Systems


Weather decision support systems can be implemented across the entire scope of aviation, from takeoff to landing, to improve decision-making among pilots and other ATM professionals. Decision support systems combine integrated data collection techniques including telemetry with smart data analysis that can help to enhance safety, improve operational efficiency, and increase transparency in decision-making in the event that an accident does occur.



We specialize in technology that can make the aviation and naval industries safer, profitable, and more responsible. If you’re looking to invest in cutting-edge tech that can improve operational efficiency and ensure that your business is future-proof, get in touch with us today. Our expert consultants can help you find the right tech solutions to help you reach your goals.

Future of ATC

What is the future of air traffic control?

Despite the negative impact of the Covid-19 pandemic, the global air travel industry is still expected to expand rapidly over the coming decade. IATA predict an annual growth rate of between 1.5% and 3.8% from now until 2040, with most of this growth occurring in the Middle East and China. As our skies become busier, it’s only natural that Air Traffic Management (ATM) teams must become more efficient.


Why is technology so vital in Air Traffic Management?

Embracing new technologies is key to safe, responsible aviation in the future; by utilising the wealth of technologies that are now available, airports and ATM teams around the world can improve safety for flight crews and travellers, reduce their carbon footprint, and improve operational efficiency at the same time. This will allow airports and aviation companies to meet rising passenger demands without compromising on the safety or quality of the services they offer.


The future of ATM


The future of ATM is just around the corner. Many of the technologies that we predict will gain traction over the next couple of decades are already here, and being implemented by some of the most advanced and progressive airports around the world. Let’s take a look at those technologies that will no doubt be ubiquitous in Air Traffic Management facilities across the globe by 2040.


Air Traffic Management Automation Systems (ATMAS)


An Air Traffic Management Automation System can partially automate the ATM process in order to provide safer, simpler ATC services. Automated ATC solutions can increase visibility at airports, ensure that air traffic controllers have access to important data as early as possible, and boost communication between ATM and pilots.


Electronic Flight Strips (EFPS)


Electronic Flight Strips can be used to replace analogue flight strips in air traffic control towers. EFS look and work in a very similar way to analogue strips, but they can be configured to both the flight tower and the individual user. EFS improve operational efficiency within air traffic control teams by allowing for real-time data updates and enabling ATM teams to share data with stakeholders in order to inform data-driven decision-making.


General Information Monitoring Systems (GIMS)


Information Monitoring Systems of various different kinds are now used by aviation specialists to track and monitor the health and status of aircraft and other important assets. The best example of a GIMS in modern aviation is Aircraft Health Monitoring Systems, which can provide real-time data about the health and condition of an aircraft to ATM teams and engineers on the ground, enabling faster response times and empowering airlines to take a more dynamic approach to aircraft management.


Departure/Arrival Manager Systems (DMAN/AMAN)


Accommodating departing and arriving planes is often considered to be one of the main bottlenecks in airport capacity; if airports can manage departures and arrivals more efficiently, it’s possible to increase capacity safely and economically. Automated DMAN and AMAN systems can make it easy to manage departures and arrivals in the most efficient way by offering a suite of tools that can be used by ATM teams to manage runway allocation, departure schedules, flow planning, and much more.

Over the next 20 years, airports around the world will be investing in technology that can make the aviation industry safer, greener, and more economical. Contact us to find out how we can help you take your first steps towards clean and responsible Air Traffic Management today.

Making Airports Safer

Making airports safer

There is no question that the aviation industry has been one of the hardest hits during the global Covid-19 Pandemic. Early travel restrictions, border closures and a high level of uncertainty all contributed to a drop in airport business of up to 30%, according to the International Civil Aviation Organisation (ICAO).


But at the same time, with frequent air travel an integral part of both business and personal life for many, there is very clear evidence that travellers want to get back to travelling ‘normally’ as quickly as possible.


Confidence is the key


Confidence is of course the absolute key factor when it comes to encouraging the travelling public back to airports. In many ways, this is simply an extension of one of the foundations that mass air travel has been built upon. Passenger confidence, at every stage of the journey experience, has been a vital psychological factor for many years.


Bayanat Engineering has played a critical role in providing much of the technological underpinning that delivers the vital feeling of safety and security for passengers, whether through advanced anti-terrorist scanning technology or highly sophisticated Air Traffic Control (ATC) systems that keep schedules running smoothly and safely.


Therefore, it’s entirely natural that the company should now focus some of its technical expertise on helping to address the many issues that Covid-19 presents – a recent example being the body temperature scanning systems featured elsewhere on this site.


Technical Solutions


Bayanat is also working with airport management to examine possible technical solutions to some of the other aspects that have been identified by world authorities as key to building a safe and comfortable airport environment as passengers begin to return in significant numbers.


Much attention is focused on the twin elements of space and time. COVID-19 has made all of us far more aware and protective of personal space, which is identified as one of the most essential measures for control of the disease. In the airport context, this means more space at check-in, security, passport control, boarding gates – every stage of the passenger’s progress through the airport. More space translates directly into more time required to properly complete each essential function safely, and a great deal of work is underway to optimize all the processes. Technology will play an important role, and Bayanat will continue to deliver innovative solutions to help make the processes as smooth and comfortable as possible.




The other great debate is of course concerning the roll-out of vaccines and the possible impact that vaccination may make in helping aviation get back up to speed. At the moment, there are perhaps more questions than answers available about this subject, with various ‘vaccine passport’ schemes and other approaches under active discussion.


In the meantime, airport and airline management around the world, and not least at Qatar, which is proud of its global reputation as one of the world’s safest airports, continue to plan intensively and test new innovations rigorously.


Safe and secure


Everything is sharply focused on one goal; to get people back to feeling safe, secure and properly cared for on their journey through the airport – and onwards to their destination. The aviation industry has overcome many challenges in the past, and it has the technical expertise required to overcome this one.

Military Defence Systems and its importance

What is a military defence system?


A military defence system is a broad term which can describe the weaponry available for the defence of a region including implements of war such as munitions, weaponry and technology. When it comes to the aviation industry, it’s important to be aware of any potential threats which could ensue and what type of military defence systems could affect your operations. High-profile cases like the shooting down of the Ukraine International Airlines flight 752 over Iran, where all 176 passengers and crew died, have led to greater calls for scrutiny over where passenger airlines are willing to fly and whether they should. But just how can passenger aircraft be protected from these threats?


Military defence systems and aviation


There are a variety of different types of military defences which can make up a country’s military defence system, from advanced surveillance systems to anti-aircraft defence systems located way out at sea. It’s also important to consider any other threats such as shoulder-fired missiles and MANPADS that may affect planes in the air. Anti-aircraft defences are military systems involving land, sea or air-based weaponry which is designed to protect against an attack from the air. There are also missile defence systems which are used to track, intercept and destruct attacking missiles and designed to shield a country from incoming missiles.


Protecting passengers in flight


It is important that professionals in the aviation and aerospace industry utilise a range of early warning systems to provide surveillance for planes while they are in the air. An early warning system attached to an aircraft scans hundreds of kilometres of airspace using a radar system to detect any threats. These threats, like unknown aircraft or ballistic missiles, can then be communicated quickly to air traffic controllers on the ground and a response can be launched. Other in air defence systems utilise thermal cameras which are linked to a laser that can deflect missiles by firing at the incoming missile’s navigation system so it misses it’s target. Some have been advocating for a greater introduction of mounting active defences on civil aircraft, however they can be incredibly costly and heavy and haven’t been widely adopted.


Maintaining safe skies


Keeping air travel safe and secure is crucial for the aviation industry, and being able to protect passengers safe while they are onboard needs to be a top priority. Regularly assessing flight paths, sharing information with governments and military and introducing advanced surveillance equipment can all be important steps to making sure everyone can travel with confidence. Airline managers should also consult with foreign affairs and security experts to determine the risks involved with flying over any potential military conflict zone. It is also wise to have minimum altitudes when flying over certain regions to make sure that planes are out of reach from man-portable missile systems.

Security solutions inside airports

Security solutions inside airports

With the ever-rising security challenges that today’s airports are having to deal with and managers are taking care of, it makes it even more important that the criteria for safety, security, and automation at airports are met. Read on to learn about some of the top security solutions inside airports today.


Drone detection systems


While air traffic control towers won’t be able to see your drone, drone detection and radar systems can be used to detect and find drones.


Drones are a major security and safety breach at airports and can be the cause of disruptive and dangerous incidents as well as security breaches. As there are more people who have remote-controlled drones for their private use, the number of drone incidents is slowly increasing. For this reason, operators need to make sure that they properly assess a threat visually and establish whether a drone is carrying explosives or cameras.


By installing cameras along the perimeter of the airport fence alongside the radar technology, you can detect drones a lot clearer. How? Once the radar is triggered, the system will relay 3D coordinates to the closest security camera to confirm whether the object is a drone or something else. Not only is this a safe solution, but highly cost-efficient too.


Airport perimeter security


People who breach the perimeter fence and access the runway are a huge threat at airports. That’s why it’s important to detect these incidents as early as possible. However, this can be a challenging task. Operators who are monitoring live video footage could miss important scenes. That’s where built-in video analytics and metadata come in. By adding structure to video images, you can identify suspects even in dark areas. The built-in infrared illuminators will detect objects that are approximately 550 meters away and thermal pictures will allow you to detect any suspects who may be hiding in trees.


Whenever an intruder comes near the perimeter, the cameras will follow them over long distances while showing their speed, size, and location to allow a quick intervention. Added bonus – false alarms signals from operators are significantly reduced.


Surface Movement Guidance & Control Systems (ASMGCS)


Long queues and crowded areas at the airport are not only frustrating for passengers, but they pose a huge security risk. How? Travellers who are standing in the queue are exposed to potential attackers and are among people who could be carrying dangerous materials. That’s where intelligent cameras come in. They minimise the number of these situations by preventing the queues from becoming too long.


A video solution also offers movement guidance on the number of people waiting at each checkpoint and those who have passed, making it easier to monitor.


Feel free to get in touch with Bayanat Engineering for more information, guidance and support on security solutions inside airports. With specialism and expertise in air traffic management and airside and terminal systems, our professional and friendly team is happy to provide a wide selection of solutions to fulfil the needs of airport authorities and civil aviation.
