What is the principle behind rigidity in space for a gyroscope?

It wobbles in response to external movement.
It rotates freely without maintaining orientation.
It maintains a fixed position in the plane in which it is spinning. (correct)
It changes directions based on external forces.

What is the main function of an attitude indicator in a gyroscopic instrument?

Indicate the altitude of the aircraft.
Display the orientation of the aircraft relative to the horizon. (correct)
Measure the speed of the aircraft.
Calculate the distance covered by the aircraft.

What is precession in a gyroscope?

The spinning of the gyro on its axis.
The turning and tilting of a gyro in response to pressure. (correct)
The gyro maintaining its orientation.
The wobbling movement of the gyro.
