Chapter 2.5 - Descending Flight

Question 1

A power-off descent is called?

Answer 1

A Glide.

Question 2

Descents are made at what speed?

Answer 2

A constant Airspeed.

Question 3

The optimum performance for a Glide is?

Answer 3

Maximum Distance for the amount of Altitude Lost.

Question 4

An Aircraft’s best Glide Speed is the same as?

Answer 4

Best Lift/Drag Ratio.

Question 5

Name 2 factors which can reduce the optimum Glide Speed?

Answer 5

• Changes in Airspeed.

- Changes in Pitch Attitude.

Question 6

When lowering the flaps the Glide performance reduces because?

Answer 6

• Lift/Drag Ratio is reduced.
• Rate of Descent is increased.
• The Nose Attitude is lowered.

Question 7

Flaps reduce the Stall Speed and thus decreases what in a Glide?

Answer 7

Landing Distance.

Question 8

Flaps should only be lowered when Airspeed is?

Answer 8

Equal of below the maximum flap operating speed.

Question 9

Flaps should only be raised when Airspeed is?

Answer 9

Equal or above the ‘clean’ Stall Speed (48KIAS).

Question 10

Headwind does what to an Aircraft during Glide?

Answer 10

Steepens Glide Path and reduces Glide Distance.

Question 11

Tailwind does what to an Aircraft during Glide?

Answer 11

Flatter Glide Path and increases Glide Distance.
