Vacuum Driven Gyro Instruments

Question 1

What is meant by ‘Rigidity in Space’ in gyroscopic instruments?

Answer 1

Will remain fixed in its plane despite outside forces

This property is essential for maintaining a stable reference in aviation and navigation.

Question 2

What is Precession in the context of gyroscopic instruments?

A spinning object (e.g., a gyroscope) will exhibit a turning force ________ to the direction of spin.

Answer 2

Perpendicular

This phenomenon can affect the accuracy of gyroscopic instruments if not properly managed.

Question 3

What does the Attitude Indicator (AI) show?

Answer 3

Shows bank and pitch

The AI is crucial for pilots to understand the aircraft’s orientation relative to the horizon.

Question 4

How quickly should the Attitude Indicator (AI) come erect after engine start?

Answer 4

Within a few minutes of engine start

A delayed response may indicate a malfunction in the instrument.

Question 5

What may the Attitude Indicator (AI) show during acceleration?

Answer 5

Pitch up (pitch down) during acceleration (deceleration)

This behavior can help pilots anticipate changes in aircraft attitude during flight maneuvers.

Question 6

What does the Directional Gyro (DG) reflect?

Answer 6

Changes in heading

The DG helps pilots maintain their intended course during flight.

Question 7

What must the Directional Gyro (DG) be calibrated to?

Answer 7

Magnetic compass

Calibration ensures that the heading displayed by the DG is accurate.

Question 8

Why must the Directional Gyro (DG) be recalibrated periodically?

Answer 8

Due to precession, to correct magnetic heading

Regular recalibration is necessary to ensure accurate navigation.
