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.

NOTE

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.

WARNING

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.

Procedures

NOTE

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 30 angle of bank clearing turn (in either

direction) for a minimum of 180 (or two 90 turns), maintaining airspeed and

altitude.

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.
