A stall is likely when an aircraft’s angle of attack is greater than the critical angle of attack without any compensatory power setting. To safely avoid and recover from a stall and possible subsequently fatal spin:

  • Be alert and prepared at all times to face the unexpected
  • Keep your wings and airframe clean and clear of ice, anticipate bad weather and stay in Visual Meteorological Conditions (VMC)
  • Keep a safe margin from the stall angle of attack by keeping always a safe speed. When manoeuvring, the load factor and the stall speed increase, so keep the speed up!
  • Apply immediate recovery action whenever the stall warning sounds or if the aeroplane does not normally react to your control inputs
  • Relax any back pressure on the control column or move it forward centrally to reduce the angle of attack. In a turn, beware not to induce yaw by roll while moving the column to the centre
  • Be gentle on the stick or wheel to avoid secondary stall or spin
  • Apply power with care so that resultant forces do not make the situation worse.
  • Read, understand and remember the contents of the Aircraft Flight Manual and Pilot Operating Handbook for your aeroplane
  • Remember the stall indicated airspeeds for the different flap settings
  • Recognise the stall warning indications for your aeroplane and maintain your handling skills by practising your stall avoidance and recovery procedures regularly at a safe altitude preferably with an instructor
  • Seek advice from an instructor if you are unsure of any technique
  • Know the behaviour and feel of your aircraft at a high AoA, so that you can use this behaviour and feel to detect when you are close to stall
