April 20, 201313 yr n EDDP some pilot's switch on engine anti ice as this increases N1 and they can climb some slope's without advancing the throttles... pure lazyness which is really not good in view to maintenance costs but they doesn't care about So they keep the thrust levers at idle and use the anti-ice switches to taxi? I can't see the engines providing enough thrust to move a heavy aircraft solely with anti-ice. Lastly if the airline sop's doesn't request full thrust, it's the decision of the responsible captain or PF (not sure about that). I think it's the dispatcher in operations that provides the takeoff performance numbers and the crew just accepts those numbers and authorizes the downlink or inputs them manually, Kenny Lee"Keep climbing"
April 22, 201313 yr Author Many thanks, again, for all the helpful advice--it's like an extension of the tutorials... And, Alexander, I want to thank you for including your fine MD-11 video. Is there a way to enlarge the picture? I couldn't find the usual YouTube enlarger hot spot, and I would like to better-read the input on the FMC screen...There is also a lot of other useful info in the video, which I find helpful...The MD-11's FMC seems more unique and different than some of the others I've gotten familiar with. But, I'm steadily learning what it takes to get it to perform as desired...It's a great airplane and fun to learn to operate it correctly...Thanks, again... Lee
April 23, 201313 yr Hi, TOPCAT: (Takeoff performance calculator) could help you if you give it your a/c weight, enter meteo conditions rwy in use (and dry or wet etc.) it can work out best flaps setting for takeoff, max de-rate Vspeed etc.... Very useful . Best Regards Andrea Buono
