Stall in landing configuration or approach configuration is essentially the same thing.
Many different ways you can practice a stall and it’s recovery and you should try them all under guidance:
- Wings level, maintaining altitude.
Landing config and power to idle and try and maintain altitude till the aircraft stalls. Attempt minimum altitude loss in the recovery without a secondary stall.
- Wings level, descending.
Landing config, power idle and trim for approach speed. Then slowly raise the nose while still continuing the descent as if you are trying to extend the glide on final.
- Banking, maintaining altitude.
Landing config or approach config.
Power idle and you’re mimicking a turn in the circuit.
- Banking, descending.
Landing config, power idle.
Mimicking a descending turn in the pattern.
Now do all of the above with different flap settings from UP to FULL down.
Purpose of all these excercises is multiple. Develop muscle memory for the recovery. Steer away from the ‘mental’ picture that the aircraft can only stall in one attitude in one configuration.
Honestly you’ve been done a disservice in your pilot training if you haven’t been taught all of the above plus all the ‘power-on’ variations.
