The autopilot is in heading select mode, and the aircraft is flying on a heading of 270°. If you change heading to 360°, the flight director command bars will;

roll command bar moves to right and centres when AFDS angle of bank to intercept has been achieved

roll command bar goes full deflection right and then doesn’t move until the aircraft heading is within 30° of the selected heading

the heading command bar will disappear and the heading hold will disengage

roll command bar moves to the right and then progressively returns to the centre as the deviation from the selected heading reduces

A Yaw damper indicator will indicate to the pilot:

yaw damper movement of rudder position

rudder position due to pedal displacement

yaw damper movement on ground only

The Autothrottle is set to climb at a constant mach number. If the temperature does not change, what happens to the CAS?

Increases, but only if the outside air temperature decreases

The interception of the localiser beam by the autopilot is:

a mode using an interception verses radio deviation law

a mode using an interception verses range computation
