In the video below an A5 had an accident after takeoff. The final cause of the accident seems to be a sharp increase of AOA above stall.
Do sea planes have an alternate technique for takeoff from tight spaces. Let me draw what I mean: So in case 1 take distance available for T/O is not enough. Is there a procedure such as in case 2, where you use one side of the lake to accelerate to some speed and then turn to main leg to complete the takeoff?
