411a:. .I flew the Lockheed 1011 for five years and I don't remember any different " feel" at heavy weights. Also the Lockheed training captains who were also Lockheed production test pilots never suggested anything about modifying the rotation rate under any conditions. Their attitude was do it the same each time and that was good enough for me. What is your reasoning for doing it differently ???. .. .Blip:. .You think too much. If you don't do it corectly all the time how in the name of heaven are you going to do it right when things are going wrong.. .Different type ratations on different days does not make sense to me. . .. .Lord Melchet:. .It's something someone else ( the expert) teaches you. First it feels right, second it looks right and third it is right. You don't need any fancy number counting. . .. .Prince of Dzun
