Answer 1

Maneuvering speed

Question 2

What does the red line on an airspeed indicator represent?

Answer 2

Vne - Never-exceed speed

Question 3

Refer to figure 4 (airspeed indicator) What is the caution range of the airplane?

Answer 3

The caution range is color coded Yellow and is 165 kts to 208 kts

Question 4

Refer to figure 4 (airspeed indicator) The maximum speed at which the airplane can be operated in smooth air is?

Answer 4

The max operating speed in smooth air is color coded in Yellow (caution range). 208 kts

Question 5

Refer to figure 4 (airspeed indicator) What is the full flap operating range of the airplane?

Answer 5

The flap range is color coded in White on the airspeed indicator. 55kts - 100kts.

Question 6

Refer to figure 4 (airspeed indicator) What is the maximum flaps-extended speed?

Answer 6

The flap extended range is color coded in White and the max speed Vfe is 100 kts.

Question 7

Refer to figure 4 (airspeed indicator) Which marking identifies the never-exceed speed?

Answer 7

The Red radial line

Question 8

Refer to figure 4 (airspeed indicator) Which color identifies the power-off stalling speed in a specified configuration?

Answer 8

Vfe - Upper limit of the White arc.

Question 9

Refer to figure 4 (airspeed indicator) Which color identifies the normal flap operating range?

Answer 9

The White arc.

Question 10

Refer to figure 4 (airspeed indicator) Which color identifies the power-off stalling speed with wings flaps and landing gear in the landing configuration?

Answer 10

Vso - Lower limit of the White arc.

Question 11

Refer to figure 4 (airspeed indicator) What is the maximum structural cruising speed?

Answer 11

Vno - The maximum structural cruising speed is the upper limit of the Green arc. 165kts.

Question 12

What is Calibrated airspeed (CAS)?

Answer 12

CAS is IAS corrected for installation and instrument errors.

Question 13

What is True airspeed (TAS)?

Answer 13

TAS is CAS corrected for density altitude. TAS is the true speed of an airplane through the air.

Question 14

What other airspeed limitation that is not found on the face of the airspeed indicator?

Answer 14

Va - Design maneuvering speed
Vlo - Landing gear operating speed
Vx - Best angle-of-climb
Vy - Best rate-of-climb
Vglide - airspeed that provides the best lift/drag
Vh - Maximum continuous power speed
