APPROACH TURN STALL
Description. Stall the aircraft while simulating a landing approach and recover safely with
a minimum loss of altitude.
General. The approach turn stall (ATS) may occur during an approach to landing. This
stall is a good illustration of what can happen when a pilot is concentrating on reaching the
runway and continues to raise his nose to stretch a power-off glide, rather than adding power to
make the runway. This stall is practiced so that the pilot will learn to recognize the approaching
stall and the complete stall, and to recover with a minimum loss of altitude.
Stalls should be practiced to the maximum extent to build
confidence and proficiency. In all cases, however, departure from
controlled flight shall be avoided. Instructional time should be
used to practice successful recovery techniques rather than test the
student's ability to recover from uncontrolled flight. It is stressed
that during an actual approach, a waveoff should be executed at the
onset of rudder shakers, as the aircraft will be approximately 100-
200 feet AGL rolling final.
Rapid divergence to extremely disorienting post-stall gyrations and
incipient spin may occur if improper control inputs are applied. If
steady-state spin is entered at 7000 feet, the crew will have less
than 15 seconds to recover before the 5000 feet bailout decision
altitude is reached.
The approach turn stall may be performed before the completion of
the LSC maneuver while in the landing approach configuration.
CONFIGURATION: Position the aircraft at or above 6500 feet AGL; 90 KIAS,
level flight, gear and flaps down, Landing Checklist completed.
CHECKLIST: Perform the Stall Checklist aloud to your instructor.
CLEARING TURN: Roll into a 30º angle of bank clearing turn (in either
direction) for a minimum of 180º (or two 90º turns), maintaining airspeed and
Roll out of the clearing turn, reduce power to 300 ft-lbs., and set the 90-KIAS
descending attitude (horizon ⅔ of the way up the canopy). Trim left rudder, nose up.
