Q

What does the knob on the Directional Gyro do?

A

Locks the gimbals so the compass can be manually realigned

Spring Loaded, thus disengaging right away

17
Q

What shows the heading of the aircraft?

A

Lubber Line

18
Q

When poor visibility exists, what instrument do we go to?

A

Attitude Indicator

19
Q

The Attitude Indicator has its spin axis?

A

Vertically

20
Q

What precess’ the gyro to the vertical if it is displaced?

A

Pendulous vanes and air jets

21
Q

Difference between Electric Attitude Indicator and Attitude Indicator?

A

small electric motor is the rotor

22
Q

A warning flag will be in view on the EAI when?

A

Electrical Power Loss

23
Q

What instrument added command bars and provides visual steering to the pilot?

A

ADI

24
Q

How much rpm does a gyro normally operate at?

A

20,000 - 24,000

25
Q

After powering down what must you not do?

A

don’t handle the gyro for 20min
