Question

What autopilot function should you turn off if icing is suspected?

1) Altitude Hold
2) Heading Hold
3) Autothrottle
4) Autopilot Master

Answer 1

The autopilot function that should be turned off if icing is suspected is the Autopilot Master.

Step-by-step explanation:

If icing is suspected, the autopilot function that should be turned off is the Autopilot Master. The Autopilot Master function controls all the other autopilot functions, and turning it off will disengage all autopilot modes. This is necessary because ice can cause the sensors and instruments to malfunction, leading to inaccurate readings, which can affect the autopilot's performance and compromise safety.
