return fire!!

I'm sorry, but I have to defend myself here...
VMCA is a minimum controll speed. That meens that the actual controll speed during flight will change, I agree fully, but it will always be lower than VMCA, so if you keep over this speed, you will be able to maintain directional control for sure, no matter what configuration you are in. Maybe when you let your speed drop below VMCA you get lucky, but I wouldn't base my life on the luck of the draw...

And as this is the heart of the discussion and the definition of VMCA, that is why I was "picky"...

Further I have not the slightest wish to say anything about the flying capabilities about anyone here on the board, so if I gave you that impression, I humbly apologise. That never was my intention, I save my opinion on your flying untill I have actally seen you perform, but then I will be strict and firm in my verdict!!!

Howerver, I stay with my opinion that VMCA is based on a worst case scenarion, although I give you points for the fact that it is never stated anywhere this explicit. And the Seneca in which I did most of the training normally also has 0 flaps for take-off, so that point is also out of the discussion. But, just after rotation, low speed, high angle of attack, one engine windmilling, one t/o pwr, a.s.o., give me an example where there is actual a worse case? I will prove you that any case is better than this (purely looking at directional controll, that is).

eagerly awaiting your response...
