• Speed brake lever not in the retracted position or ground spoilers armed and:
  • Both main landing gears on ground,
  • Both thrust levers at or below Idle position, or Reverse selected on at least one engine (and the other thrust lever below MCT position).
• Speed brake lever in the retracted position but ground spoilers not armed and:
  • Both main landing gears on ground,
  • Reverse selected on at least one engine (and the other thrust lever below MCTposition).

The ailerons are fully-extended (Aileron Anti Droop@ ), provided one aileron servocontrol is available on each side, when:

• The ground spoilers are fully extended
• Flaps are not in clean CONF
• Pitch attitude is lower than 2.5 °
• Flying manually
• In normal law only."

Shortly after introduction of the 320(1) in our airline, Lufthansa had an accident on landing at Warsaw.
Our 320 TP asked the rest of us what the spoiler logic was on our aircraft - as at that time at least one mainwheel on each side had to have spin up. Airbus had canvassed the airline TPs.
On the MD, which was “my” ship, any two main wheels - both one the same side - or one on each side - or more, would trigger the spoiler. I believe shortly after this, the same logic was employed on the 320.
