A radar antenna is facing left. On ground test, if you move the vertical gyro to simulate a right bank, the antenna
- will move up
- will move down
- will not move
Explanation from PART66Online
The weather radar antenna is roll-stabilised so its beam stays level with the horizon regardless of aircraft attitude. Simulating a right bank raises the left side of the aircraft, so an antenna pointing left must tilt downward to keep the beam pointing at the true horizon, which is why it moves down during the gyro stabilisation test.
