Ok, I don't know if there are any official procedures to deal with this, but given this hypothetical situation, what would you do?
- V1, VR etc. calculated based on a certain flap configuration
- After V1 there begins an uncommanded retraction of the flaps
Clearly you are above V1 so you can't abort the takeoff - I assume you would run up a bit more speed before rotation and begin with a shallower rate of climb whilst trying to rectify the problem?
Merely a hypothetical situation I was pondering a while back!
