September 2, 201312 yr Uhh - ever heard of manual thrust? The thing has so much power empty, that yes, it is normal to either accelerate rapidly (shallow climb angle, relatively) or a very high pitch attitude in order to keep the speed in check against the thrust. The way I handle it without proper tables for calculating FLEX is that I use full power takeoff as normal, but NO auto-throttle. I rotate to 20 degrees of pitch (keeping the gear in the airflow for additional drag), then just pull the thrust back very slightly to keep the speed in check, then gear up. There is absolutely nothing saying you can not do this, because your climb angle is such that there isn't a problem with terrain avoidance. Of course, if you're empty, or hauling freight, then keep on pitching! :lol: :wub: Aerodynamically there is no reason why you can't pitch to 40 degrees if you have the power to maintain airspeed. It's all about the flow over those wings and excess thrust to defy gravity. ^_^ Just be ready to push in the event of engine failure. Best regards, Robin. Do you not see the irony in someone who thinks de-rating is dangerous, yet arbitrarily powers down the aircraft limiting climbing capabilities? :lol: Luke Harvest
September 2, 201312 yr Commercial Member Ahh but the initial takeoff run and initial climb was at TOGA, meaning shortest runway distance used, and shortest distance to 35 ft. Power was only pulled back after the climb was established, simply to keep the speed in check. I'll bet 5 miles after takeoff, I'm higher than your Flex takeoff would have you. Best regards, Robin.

Problem is, that is dependent on so many factors it's not even worth discussing. My point is that it's nonsensical to want to use as little runway as possible, and not sacrifice power, but to then not take advantage of all the power (which has a much smaller effect on the engines' longevity than using TOGA) to climb-out and safely gain as much altitude as possible in as short a time-frame as possible.

September 2, 201312 yr Commercial Member I was responding to the OPs issue of "speed runaway" during climb-out, and a valid technique for keeping it under control. I've no problems climbing like a Delta II. :lol: Best regards, Robin.
