Airplane Systems

Question 1

What is the purpose of the wing flaps?

Answer 1

Their purpose is to permit a slower airspeed and a steeper angle of descent during a landing approach. Also may be used to shorten takeoff distance.

Question 2

What instruments operate from the pitot/static system?

Answer 2

The pitot/static system operates the altimeter, vertical speed indicator, and airspeed indicator.

Question 3

How does one determine indicated altitude?

Answer 3

Indicated altitude is the altitude read directly from the altimeter after it is set to the current altimeter setting.

Question 4

How does one determine true altitude?

Answer 4

True altitude is the true vertical distance of the aircraft above sea level.

Question 5

How does one determine density altitude?

Answer 5

Density altitude is the pressure altitude corrected for nonstandard temperature variations.

Question 6

What are the different types of aircraft speeds?

Answer 6

1. True airspeed
2. Indicated airspeed
3. Calibrated airspeed

Question 7

What airspeed limitations apply to the color-coded marking system of the airspeed indicator?

Answer 7

white arc = flap operating range
lower white arc = stalling speed, dirty
upper white arc = maximum flap extension speed
green arc = normal operating range
lower green arc = stalling speed, clean
upper green arc = maximum structural cruise speed
yellow arc = caution range (operations in smooth air only)
redline = maximum operations in smooth air only
