Question 7

Concerning the flight warning system (FWS), advisory messages may be:

Accepted Answer

Any colour except red, and preferably not amber.

Answer

Any colour except amber.

Answer

Red.

Answer

Any colour except green.

Question 8

During a climb, the total pressure probe of the airspeed indicator becomes blocked

Accepted Answer

Decreases by 1% per 600 FT.
