Slow Flight
-
Slow Flight Maneuvers should be performed at a minimum of 1,500 feet AGL. At Kalamazoo, we will perform Slow Flight at 3,000 feet MSL.
-
In the Cessna 150 and Cessna 172, we will aim to keep the airspeed between 55-60 mph indicated. We will aim to keep the altitude no more than 100 ft high or low from 3,000 ft. MSL.

Power-Off Stall
-
Power-Off Stalls should be performed at a minimum of 1,500 feet AGL. At Kalamazoo, we will perform Power-Off Stalls at 3,000 feet MSL.
​
​
The following list shows each step of setting up and performing the intended stall. It is extremely helpful for the student to have each step memorized before going to the flight lesson (Suggestion: Write them on a note-card to memorize):
Power Off Stall:
Set-Up:
-
Clearing Turn (90 degrees in each direction)
-
Carb Heat
-
Power Back 1800 RPM
-
Airspeed in white arc
-
Flaps Down
-
Pitching down as flaps extract (maintain at least 70mph)
-
Power Off
Initiation:
-
Begin pitching up
-
Maintain directional control (Aileron + Rudder as needed)
-
Maintain pitch as airspeed slows
-
Stall horn
Recovery:
-
Stall is recognized by rapid pitching down or buffeting (shaking of wings)
-
Full Power
-
Carb heat off
-
Forward pressure to prevent aircraft from pitching up
-
Right Rudder
-
Hold until airspeed reaches white arc again and is SAFE
-
Retract 10 degrees of flaps
-
Check Airspeed
-
Continue retracting flaps and maintaining safe airspeed while beginning to climb

Power-On Stall
-
Power-On Stalls should be performed at a minimum of 1,500 feet AGL. At Kalamazoo, we will perform Power-Off Stalls at 3,000 feet MSL.
The following list shows each step of setting up and performing the intended stall. It is extremely helpful for the student to have each step memorized before going to the flight lesson (Suggestion: Write them on a note-card to memorize):
Power On Stall:
Set-Up:
-
Clearing Turn (90 degrees in each direction)
-
Carb Heat
-
Power Back 1800 RPM
-
Airspeed around 65mph
-
Return to ~80% power, carb heat off
-
Pitch to relatively steep climb
Initiation:
-
Continue back pressure and pitch as airspeed drops
-
Maintain directional control (Aileron + Rudder as needed)
-
Stall Horn
Recovery:
-
Stall is recognized by rapid pitching down or buffeting (shaking of wings)
-
Left aileron and release right rudder
-
Full Power
-
Pitch back to straight and level
-
Begin climbing once airspeed is safe again
