Question 23

During normal operation of a vacuum driven attitude indicator, what attitude indication should you see when rolling out from a 180 degree skidding turn to straight-and-level coordinated flight?

Answer 23

The miniature aircraft shows a turn in the direction opposite of the skid.

Sustained turns induce an error into the attitude indicator that is opposite the sustained turn; the longer the turn takes, the larger the induced error

Question 24

During normal coordinated turns, what error due to precession should you observe when rolling out to straight and level from a 180 degree steep turn to the right?

The miniature aircraft would show a slight turn indication to the left

Error in both pitch and bank indication on an attitude indicator are usually at a maximum as the aircraft rolls out of a

Answer 26

180 degree turn

Question 27

If a 180 degree steep turn is made to the right and the aircraft is rolled out to straight-and-level flight by visual references, the attitude indicator

Answer 27

may show a slight climb and turn

Question 28

One characteristic that a properly functioning gyro depends upon for operation is the

Answer 28

resistance to deflection of the spinning wheel or disc

Question 29

How should you preflight check the altimeter prior to an IFR flight?

Answer 29

Set the altimeter to the current altimeter setting. The indication should be within 75 feet of the actual elevation for acceptable accuracy.

Question 30

When airspeed is decreased in a turn, what must be done to maintain level flight?

Answer 30

Decrease the angle of bank and/or increase the angle of attack

Question 31

The primary reason the pitch attitude must be increased, to maintain a constant altitude during a coordinated turn, is because the

Answer 31

vertical component of lift has decreased as the result of the bank
