Question 1

In a directional indicator, a heading ring attached to the outer blank drives a display card.

Answer 1

Gimbal

Question 2

Directional gyroscope must be re-synced with the compass every X minutes.

Answer 2

10.

Question 3

What does a horizontal situation indicator do?

Answer 3

Adds magnetic indicator needles to directional indicator.

Question 4

Directional gyroscopic drifts over time due to three reasons :

Answer 4

Earth rotation / aircraft manoeuvres / transport error

Question 5

Explain what happens when directional gyroscopes experience drift due to aircraft manoeuvres.

Answer 5

Gyroscope moves out of alignment as it tries to erect relative to the aircraft.

Question 6

Explain what happens when directional gyroscopes experience drift due to transport error.

Answer 6

Moving east produces drift the same as earth rotation but moving west produces opposing drift.

Question 7

Explain what happens when directional gyroscopes experience drift due to earth rotation.

Answer 7

The drift is proportional to the sine of the latitude.

Question 8

In the gyromagnetic compass, the heading information from the flux valve is sent to the… blank detector.

Answer 8

Error.
