CROSS-CONTROL STALL

Description

A stall resulting from crossed controls: aileron pressure applied in one direction and rudder pressure in opposite direction.

Objective

To demonstrate the effect of improper control technique and to emphasize the importance of using coordinated control pressures when making turns.

Setup

·         Clear the area

·         Choose forced landing area

·         Configure aircraft for final approach for landing: CCGUMPS, approach power (C172RG: 15” Hg, 2700 RPM), flaps up (flaps down will lead to excessive loads), gear extended, carburetor heat on, altitude so recovery is ≥1500’ AGL

·         Select outside references

·         Reduce power to idle

·         Maintain altitude until a normal glide (C172RG: 65 KIAS) and trim to relieve control pressures

·         Roll into a medium bank turn (20-30º) once on simulated approach

·         Apply heavy rudder pressure in the direction of the turn

·         Apply opposite aileron pressure to maintain the bank

·         Increase back elevator pressure to keep the nose from lowering

·         Increase all flight control pressures until airplane stalls

Recovery

·         Immediately release all control pressures and, if necessary, allow the roll to continue until airplane reaches upright and level flight

·         Increase power to full to climb and recover

·         Maintain ball centered

·         Look for traffic
