Wino:. .I do not agree with what you say about attitude and V2. You cannot expect to hold V2 with an engine failure at V1 if you don't reduce the normal pitch attitude by some small amount. My memory for the B747 classic puts this at 2 degrees less for 3 engines. Company procedures required the take off data card to be displayed prominently for both pilots to see and the top lines on the card (in big printed letters) said:. .. . 4 engines 15 degrees. . 3 engines 13 degrees. .. .This took care of the max take off weight engine failure at V1 as 13 degress always without fail gave exactly V2. Of course any weight less than max gave a higher speed. The point is that by holding the selected attitude steady the climb out profile was always assured. Easy: no thinking required. It was not for me to question this. My job was to do it. In conclusion, I must say I never flew a big twin so perhaps they are different. . .There is something magical about the perfect rotation. All that weight slotted just where you want it and with so little effort. Equal to a good landing because it's a small personal achievement. No one knows about it except yourself.. .. .Prince of Dzun
