What causes the DI gyro to wander

Answer 25

IMPERFECTIONS Friction

Question 26

At the poles, after 6 hours, how much will the DI drift by

Answer 26

90॰

Question 27

The amount of precission of a gyro caused by the earths rotation is dependant on what

Answer 28

Rotates in the VERTICAL PLANE about the HORIZONTAL AXIS

Question 29

In a standard rate 1 turn, how much will the heading have changed after 1 minute

Answer 29

180॰

Question 30

In a right hand banked turn, if the balance ball is to the right, is the aircraft SKIDDING or SLIPPING in the turn

Answer 34

OVER READ

Question 35

OVER READ

Question 36

What does the VSI measure in order to indicate vertical speed

CALIBRATED AIR SPEED Corrected for instrument and position error

Question 39

What is TAS

Answer 39

Question 42

What is an indicator on the altimeter that the static system has failed

Answer 42

SAME ALTITUDE INDICATED IN CLIMB OR DESCENT

Question 43

What is an indicator on the VSI that the static system has failed

Answer 43

Climb or descent will not be detected

Question 44

When the static system fails, on the ASI, will indicated airspeed INCREASE or DECREASE in each situation; 1. Climb 2. Descent

Answer 44

1. DECREASE 2. INCREASE ## Footnote Actual speed is not changing, but since static pressure is not changing, a descent or climb means the same static pressure is always being referenced.

Answer 45

1. INCREASE 2. DECREASE
