Lesson 6 : APPROACH TO LANDING STALLS

APPROACH TO LANDING STALLS

A portion of your total flight time (typically about 3%) will be involved in the landing phase of the airplane
operation. While you are in this phase the operation of the aircraft is such the you will be at a low altitude, the
airspeed will be low, and the airplane will be in a configuration that is “dirty” or is producing drag. This specific
maneuver is required not to show that you can make the airplane quit flying, but that you know what to do when the
airplane does quit flying and how you can recognize when the stall is about to happen. This is an extremely
important aspect of this maneuver because where it will happen to you in real life is where you do not have much
margin for error. You will be low over the ground, low on airspeed, probably making a descending turn to try and
get even lower and slower when the “surprise“ happens. Your goal throughout this maneuver is to conserve as much
altitude and airspeed at the same time as is possible.

Objective:
To familiarize the student with the warning signs of a stall, the reaction of the airplane when stalled and
the recovery techniques required.

Content:
1. Select an altitude that will allow an recovery no lower than 1500 AGL.
2. Perform clearing turns
3. Identify prominent landmark
4. Decrease power
a. Fuel - On
b. Mixture - Rich
c. Carburetor heat on
d. decrease power to 1500 RPM (For C-172RG set rpm to 2500)
e. Oil Pressure - in green
f. Trim (Optional)
g. cowl flaps Closed
5. Carb heat - ON
6. Reduce power

C-152 1500 rpm
C-172 1500 rpm
C-172RG 15 In Hg

7. Keep ball centered
8. When airspeed below Vfe flaps - 10°
(maintain altitude 0 rate of sink)
9. Gear handle - Down (verify gear is down)
10. Flaps - 20° (maintain altitude 0 rate of sink)
11. Flaps - 30° (maintain altitude 0 rate of sink)
12. When reaching normal landing airspeed (C-152: 55 Kts, C-172: 60kts, C-172RG: 65kts), pitch to a landing
attitude for three seconds
13. Establish Bank as directed - 30°
standard - & clear
14. Reduce power slowly to idle
15. Hold until imminent or full stall as specified by the examiner.
16. KEEP BALL CENTERED at all times
- NOTE -
For IMMINENT STALLS - Increase back pressure until stall horn sounds, or
loss of control effectiveness. For FULL STALLS - Increase back pressure until
aircraft nose drops

Recovery
1. Simultaneously decrease pitch, level wings
2. Power - increase (C-172: full, C-172RG: 25 in Hg)
3. Carburetor heat - off
4. Level wings and adjust pitch attitude for Vy.
5. Flaps - 20°
6. Gear - UP (at positive rate of climb)
7. Remaining flaps up slowly as airspeed builds up
8. Retract Flaps to 10°
9. Establish positive rate of climb
10. Retract Flaps to 0°
11. Establish positive rate of climb
12. Lower nose to cruise attitude while maintaining positive rate of climb
13. Return to original altitude and perform cruise checklist
14. When airspeed has increased decrease power

Completion Standards:
Recovers with minimal altitude loss
Maintains control of aircraft
Maintain heading within 10°
(for straight ahead stall)

Common Errors:
1. Improper approach speed - nose too high for flap setting
2. Raising the nose too fast
3. Staring blindly over the nose
4. Not keeping the ball centered through out the maneuver
5. Lowering nose before stall occurs
6. Wings not kept level ( on straight ahead stall)
7. Not relaxing back pressure and entering secondary stall
