- explain operational concepts like FANS or PBN and describe the onboard functionalities related to these concepts.

Detailed objectives:

At the end of this course, the student will be able to:

• Explain the relationship between onboard equipment and ATM operational concepts, providing some examples

• Surveillance Systems:
- Explain what is meant by airborne surveillance and safety nets
- Explain the working principle and describe the architecture and HMI of the following systems/functions:
TAWS, TCAS, weather radar, transponder and ADS-B

• Communications Systems:
- Explain the different communication needs in an aircraft (cockpit and cabin) and the different communication domains
- Identify the different communications means in an aircraft: VHF, HF, SATCOM… and their use
- Describe the architecture and HMI of cockpit communication systems

• FANS concept:
- Explain the specificities of FANS 1/A and FANS B (ATN B1): operational context, communication networks, applications…
