Stall recovery
The JS-3 has very mild stall properties recognisable by the following:
• The nose is in a higher than normal attitude relative to the
horizon.
• Slight buffeting approximately 2 km/h before the stall.
• Airspeed indicator starts fluctuating near the stall.
• A slight increase in the sink rate.
• Aileron effectiveness decreases considerably.
The stall recovery procedure is to release the pressure on the control
stick and move it towards the neutral position.
CAUTION: During stalled flight, if the angle of attack is increased by
further pulling back on the stick, a wing drop may occur.
This asymmetric stall may result in a spin if incorrect stall
recovery procedures are used.
NOTE: When a stall is initiated by pulling with the nose to a high
pitch angle (in excess of 30° above the horizon), the
nose may pitch down well below the horizon during the
recovery and the altitude loss during recovery may
exceed 60 m / 200 ft.
NOTE: When a stall is initiated with 45° bank, and the resulting
roll is not counteracted by use of opposite rudder, a loss
of altitude exceeding 100 m / 330 ft may occur.
