Mutt - Difference between my V2 and Vt is 23kts so V2 and Vxse could not be nearly as much as your bus . How much I would like to know myself since I cant find Vxse anywhere.

Now, to answer your patronizing question:

My idea of speed use in case of SE was until recently this: rotate, fly V2 (which I thought to be my Vxse.....NOT!), at 1500' fly Venr (Vyse).

Now, Mutt its your turn to shine and explain why I should fly V2 - like Cessna recommends - instead of Vxse till 1500ft. I would rather use best angle of climb till 1500ft for obsticle clearance rather then minimum flying speed. So what say you ....

formulaben - Not so fast, If you read my posts carefully you would see I that I said Vref accelerates above V2 way before I reach flap retraction height of 1500ft. Five seconds later Vref was about 10kts above V2 and flaps have not yet moved an inch.Thats why I believe speed acceleration had something to do here. Look at this picture here...
