Question

What does the AV do while waiting for the lost comm timer timeout to expire in CWS?

Answer 1

In CWS, the AV continues to control the aircraft according to the last FCU commands and flight mode while waiting for the lost comm timer timeout to expire. It also transmits 'lost comm' signals to ATC to indicate the loss of communication.

Step-by-step explanation:

In CWS, which stands for Control Wheel Steering, the flight control system of an aircraft, the AV (Autopilot/Flight Director) performs different actions while waiting for the 'lost comm timer timeout' to expire.

Firstly, the AV continues to control the aircraft according to the last FCU (Flight Control Unit) commands and flight mode. It maintains the current altitude, heading, and airspeed.

Additionally, the AV will start transmitting 'lost comm' signals to ATC (Air Traffic Control) to indicate the loss of communication. These signals are usually coded messages sent through the radio communication system.
