How to Enter and Recover from Slow Flight on a Cessna 150

Knowing how to control an airplane is a great thing to accomplish whether for recreational purposes or career involvement. With this set of instructions, an individual will learn how to control an airplane when entering and recovering in slow flight speeds.


  1. 1
    Before entering slow flight the pilot needs to maintain the airplane in cruising speeds and keep the same altitude.
    • After reaching cruising speeds of about 90 KIAS and about 2500 RPM a HASEL check is required.
    • A hassle check consists of a few steps to be safe while in flight and making sure a pilot can follow through with their intentions. check for H-eight, A-rea, S-ecurity, E-ngine, L-ookout. Including 2 clearing turns.
  2. 2
    Perform 1st clearing turn.
  3. 3
    Perform pre-flight check list. (seatbelts/shoulder harnesses, fuel shut-off value, & fuel mixture)
  4. 4
    Turn carb heat on.
  5. 5
    Progressively bring the throttle back to 1500-1700 RPM to decelerate slow flight speeds.
  6. 6
    Once airspeed indicator is in white arc, move flaps to 10 degrees.
    • Pull back on controls (nose up) to maintain altitude.
  7. 7
    Perform second clearing turn. During turn move flaps to 20 degrees.
    • Pull back on controls (nose up) to maintain altitude.
  8. 8
    Once wings are level move flaps to 30 degrees.
    • Pull back on controls (nose up) to maintain altitude.
  9. 9
    Add power to approximately 2000 RPM whenever getting close to 55 KIAS or as needed to keep altitude.
    • While in flight the left hand controls the airspeed and the right hand controls the altitude.
    • Movements are exaggerated (e.g. turns, rudder, etc.)
    • Slow flight is usually around 55 KIAS and the slow flight signs are low airspeed, unresponsive aileron and possibly stall horn.
  10. 10
    To perform power-off stall:
    • Lower nose as if looking at a runway for landing purposes.
    • Progressively begin nose up attitude (flare) and wait for stall.
    • To recover from stall, immediately add power and pull up nose (to level plane) simultaneously. Carb heat cold and slowly/incrementally return flaps to 0 degrees.
  11. 11
    To recover put the nose down (plane faces the ground) add full power.
    • Carb heat cold.
  12. 12
    (Nose up) climb back to initial altitude at 70 KIAS.


  • HASEL Check should be done before slow flight.
  • It's important not to descend more than 150 feet (45.7 m) from initial height when on slow flight.
