1) A Turn and Bank indicator contains two independent mechanisms. One of these is: Report

A ball mechanism which shows the rate at which the aircraft is turning.

A gyro which detects the amount of slip or skid the aircraft is undergoing during the turn.

A gyro which detects the rate at which the aircraft is turning.

2) The Directional Gyro indicates the heading of the aircraft. It has some advantages over a compass in that: Report

It always shows the aircraft heading relative to North.

It does not suffer from magnetic errors or oscillations.

It is not affected by precession.

3) With a Directional Gyro it is necessary for the pilot to check and reset its heading every 15 to 20 minutes as : Report

Magnetic variation will introduce heading errors.

Heading errors will be introduced by the earths magnetic dip.

It will drift, due to the earth's rotation, which introduces heading errors.

4) The knob on the front of a Directional Gyro instrument is used to: Report

Cage the gyro when it is not operating and to adjust the heading scale.

Turn the aircraft symbol so that it aligns with the magnetic heading.

Adjust the aircrafts course.

5) The purpose of a Ground Proximity Warning System (GPWS) is to: Report

alert the pilot if the aircraft is too close to the ground

alert Air Traffic Control when the aircraft is descending too rapidly

initiate automatic avoiding action when the aircraft is in danger of crashing.
