Every flight depends on reliable communication and accurate navigation. Pilots talk to air traffic control and to each other, receive weather and clearance information, and follow precise routes and approach paths. Behind all of this are avionic systems that B2 engineers maintain.

Communication systems

Aircraft carry VHF radios for line-of-sight communication with controllers, and many carry HF radios for long-range communication. An audio and intercom system connects headsets, microphones and speakers for the crew. Data link systems can also send text messages between aircraft and ground.

Navigation systems

Navigation has grown from ground-based radio aids to satellite-based systems. Aircraft use radio navigation receivers, instrument landing systems for precision approaches, inertial and satellite navigation, and flight management systems that combine these sources into one accurate position and route.

Surveillance and safety

Transponders reply to ground radar and help controllers identify aircraft. Collision avoidance and terrain awareness systems add further safety layers.

Maintaining these systems

B2 engineers carry out functional tests, check antennas, coaxial cables and connectors, replace faulty units, load software and databases where required, and certify their work. Careful handling of electrostatic-sensitive devices is essential.

Learning it at Redwings

These systems are covered in Module 13 for B2 students, building on electrical and electronic fundamentals. Practice in the radio navigation and instrument workshops helps students understand how the equipment works and how faults are found.
