Purpose of slow flight

• Develops a pilots ability to fly at low speeds and high AOA.
• To become familiar with feel, sound and visual cues of an aircraft that fly at high AOA
• Training us for when we get to stalls, our “training wheels” before we perform a stall
• Be familiar with degraded response of control inputs and making correction actions should a stall warning occurs

Common Errors

1. Failure to adequately clear the area

2. Inadequate back-elevator pressure as power is reduced, resulting in altitude loss

3. Excessive back-elevator pressure as power is reduced, resulting in a climb followed by rapid reduction in airspeed

4. Insufficient right rudder to compensate for left yaw

5. Fixation on the flight instruments

6. Failure to anticipate changes in AOA as flaps are extended or retracted

7. Inadequate power management

8. Inability to adequately divide attention between airplane control and orientation

9. Failure to properly trim the airplane

10. Failure to respond to a stall warning

Procedure

Initial Configuration  Altitude ................................................> 1,500 Feet AGL  Power ..................................................≈ 2,200 RPM  Airspeed ..............................................≈100 MPH

1. Clear the area and pick a reference point to maintain heading
   1. 3 C’s (clearing turns, call, configure)
   2. Pick a large reference point out in front of you
2. Reduce throttle to 1500 RPM
3. Add flaps
   1. “Below 110 flaps 10”
   2. Below 85 flaps full”
4. Slowly increase pitch to hold altitude
   1. “1-2 fingers above the horizon”
5. Note airspeed at stall horn, then add 5 MPH
   1. Generally 51 MPH +5 MPH
   2. ACS says to hold at the stall warning with a tolerance of + or – of 10 IAS
6. Add power to maintain altitude
   1. Approximately 1900-2000 RPM
7. Trim to relieve control stick pressure
8. Maneuver as instructed

Recovery

1. Apply full power and level the wings
   1. Gas in right pedal in
2. Slowly lower the pitch to level flight attitude while maintaining altitude
   1. “4-5 fingers below the horizon”
3. Retract flaps
   1. “Above 60 flaps come out”
4. When airspeed reaches 90 MPH, set practice area power (2200 RPM)
