Characteristic Stall

Question 1

Execution

1

Answer 1

Choose an altitude to be the level of the imaginary field

Question 2

2

Answer 2

Configure the acft for landing
Maintain level flight as in a slow flight with two points of flap
Initiate a glide at 90 KIAS and a 500 ft/min descent

Question 3

3

Answer 3

At approximately 100 ft before the selected altitude

• close throttles and slowly, but firmly pitch up to simulate a flare
• maintain this ¿until we? hear the stall warning or feel the buffeting

Question 4

Recovery

1

Answer 4

Smoothly apply 35’’ of MAP

At the same time paying attention to pitch to maintain level with the runway field

Question 5

2

Answer 5

Without allowing the acft to descend:

• Retract flap to 10º

Question 6

3

Answer 6

Accelerate acft to 90 KIAS and start to climb maintaing this speed
Once we have positive rate of climb and altimeter increasing:
- retract landing gear
- fly at 100 KIAS

Question 7

4

Answer 7

At 400 ft AGL:

• Accelerate to 110 KIAS
• Select flap 0º and
• Make a power reduction to 31.5’’ MAP and 2450 RPM
• Read the “AFTER TAKEOFF checklist

Question 8

What are the common errors in stalls?

Answer 8

• Not carrying out the sweeping turns
• Tendency to trim
• Not centering the ball
• Performing maneouver with droped wing or without maintaing the heading by use of the rudder
• If one wing stalls before the other: spin
• Pulling back too much during the recovery to not lose altitude and entering a secondary stall
• Descending below the height of the imaginary field in the characteristic stall
