CFI Oral Slow Flight, Stalls, and Spins

Question 1

What is a power-on stall?

Answer 1

1) Airplane stalls with full power

2) Simulation of departure configuration

Question 2

What is the objective in power on stall?

Answer 2

1) Familiarize the conditions which produces stalls.

2) Helps pilots to take preventative actions

Question 3

What are the standards of power on stalls?

Answer 3

1) Knowledge on stall
2) Altitude not lower than 1500
3) Power not less then 65 %
4) Heading +/- 10
5) not exceed 20 bank
6) Recognizing buffetings stall conditions
7) retract flaps during Vx and Vy speeds

Question 4

What are the common error in the performance of a power on stall ?

Answer 4

1) Not clearing area
2) improper pitch, heading and back control
3) not reducing the power to approach speed
4) increasing pitch attitude too much
5) not maintaining specified bank angle
6) rough controls
7) fail to recognize first indication of a stall
8) failure to achieve a stall
9) improper use of rudder
10 Secondary stall during recovery

Question 5

What are the advantages of a power off stall?

Answer 5

1) practice of how plane acts on pattern and final

2) Goal is to recognize the stall first

Question 6

What are the standards for power off stalls?

Answer 6

1) 1500
2) knowledge
3) decent rate 3 degrees
4) smooth transition
5) +/- specified heading no exceeding 20
6) +/-5 turning flight

Question 7

What happens in a crossed-control stall?

Answer 7

uncoordinated flight with the flight controls crossed

aileron pressure applied in one direction and rudder pressure in the opposite direction.

If excessive back pressure is applied, a crossed-control stall may result.

Question 8

Explain why the flight instructor should demonstrate the crossed-control stall to the student.

Answer 8

emphasizes the importance of using coordinated control pressures when making turns.

Question 9

When does cross control stall occur most of the time?

Answer 9

base to final approach

result of overshooting the centerline of the runway

Question 10

How is an elevator trim stall demonstrated?

Answer 10

a. Establish a specific heading and altitude (recovery by 1,500 feet AGL).
b. Perform clearing turns.
d. Extend one-half to full flaps.
e. Close throttle.
f. Maintain altitude until airspeed approaches normal glide speed.
g. When normal glide is established, the airplane should be retrimmed just as would be done during a normal landing approach.
h. Advance throttle to maximum power as in a go-around procedure. The combined forces of thrust, torque, and back elevator elevator trim will tend to make the nose rise sharply and turn to the left.
i. When a stall is imminent, forward pressure must be applied to return the airplane to normal climbing attitude.
j. Trim should then be adjusted to relieve the heavy control pressures and the normal go-around and level-off procedures should be completed.

Question 11

How is the crossed-control stall demonstrated?

Answer 11

a. Establish a specific heading and altitude (recovery by 1,500 feet AGL).
b. Perform clearing turns.
d. Reduce power.
e. Maintain altitude until airspeed approaches normal glide speed.
f. Retrim aircraft.
g. Roll into a medium-banked turn.
h. During turn excessive rudder pressure should be applied in direction of turn but the bank held constant by applying opposite aileron pressure.
i. Increase back elevator pressure to keep nose from lowering.
j. Control pressures should be increased until airplane stalls.
k. When stall occurs, recover by releasing control pressures and increasing power as necessary.
l. Control any yawing tendency with rudder.
m. Use ailerons to level wings as soon as possible.
n. As airspeed approaches VX establish climb attitude to maintain VX and to establish a positive rate climb. o. Return to cruise flight.

Question 12

What are the Practical Test Standards for cross control stalls?

Answer 12

a. Aerodynamics of crossed-control stalls.
b. Effects of crossed controls in gliding or reduced airspeed descending turns.
c. Flight situations where unintentional crossed-control stalls may occur.
d. Entry procedure and minimum entry altitude.
e. Recognition of crossed-control stalls.
f. Recovery procedure and minimum recovery altitude.

Question 13

Describe an elevator trim stall.

Answer 13

full power is applied
With excessive nose-up trim
occur during a go-around
approach or a simulated forced landing approach, or immediately after takeoff.

Question 14

Why should a flight instructor demonstrate an elevator trim stall?

Answer 14

Practice positive control of an airplane If it happens close to ground.

Question 15

Practical Test Standards of elevator trim stall?

Answer 15

a. Aerodynamics of elevator trim stalls.
b. Hazards of inadequate control pressures to compensate for thrust, torque, and up-elevator trim during go-around and other related maneuvers.
c. Entry procedure and minimum entry altitude.
d. Recognition of elevator trim stalls.
e. Importance of recovering from an elevator trim stall immediately upon recognition.

Question 16

What is a secondary stall?

Answer 16

1) Occur after a recovery from stall.

2) Happens when student thinks that stall is completed before regained sufficient flying speed.

Question 17

1. Describe a spin. (FAA-H-8083-3)

Answer 17

1) aggravated stall
2) airplane follows a downward corkscrew path.
Rotation is around the vertical axis
3) Rising wing is less stalled than the descending wing creating a rolling, yawing, and pitching motion.

Question 18

3. How should spins and spin recovery be demonstrated?

Answer 18

a. Establish the appropriate altitude; recommended minimum altitude for recovery — 3,500 feet AGL.
b. Perform clearing turns.
c. Apply carburetor heat and reduce the throttle to idle.
d. Configure the aircraft for a power-off stall (no flaps).
e. As the airplane approaches a stall, smoothly apply full rudder in the direction of the desired spin rotation and continue to apply back elevator to the limit of travel.

The ailerons should be neutral.

f. Maintain full rudder deflection and elevator back pressure throughout the spin.
g. Allow the spin to develop (approximately 2 to 3 rotations).

Question 19

What are the steps of recovery from a spin?

Answer 19

a. Close the throttle (if not already accomplished).
b. Neutralize the ailerons.
c. Apply full opposite rudder.
d. Briskly move the elevator control forward to approximately the neutral position.
e. Once the stall is broken the spinning will stop.

Neutralize the rudder when the spinning stops.

f. When the rudder is neutralized, gradually apply enough aft elevator pressure to return to level flight.
