February 14, 201610 yr Hello I am trying to get to grips with the iFly 747-400 FMC. In FSX. Can some one please explain how to increase the Thrust limit on Takeoff. Mine has a default setting of 89.6 and I cannot get it to change. I was hoping to set it around 104.5. The Aircraft is fully loaded and full of fuel Flaps set to 20 GR set 785.3 Fuel set 367.4 ZFW in small letters 417.8 Reserves 9.9 Cost Index 50 One other thing, The Autopilot Speed, Heading, and Altitude will not change. There is a caution, warning lamp on. But no Red lines on the EICAS As you can tell I need Help. (Yes I have read most of the Manual) Thank You Corrie
February 14, 201610 yr Fully loaded and full of fuel = over t/o weight ! Post in the official forums for help as you may have a bad install. Peter Schluter
February 14, 201610 yr Author Thank you Peter Unless I have miss-understood something, the Empty Weight is 317,000 lbs Payload is 98,532 lbs Fuel is 380,506 lbs Total = 796,038 lbs Well under T/O weight of 875,000 lbs. However I will try again with a lot less fuel, which I should have done anyway. Is there a way of increasing Takeoff Thrust? Corrie
February 15, 201610 yr For that takeoff weight at ISA temperatures TOPCAT calculator gives me 105.5% for the GE engines for TO setting with no assumed temperature. Have you completed the FMC set up including departure runway ? Peter Schluter
February 17, 201610 yr Author Your calculation is more or less what I thought, am still learning the FMC. Had got to Thrust LIM, and had also entered the runway. Had to leave it for a few days. Have printed off some more pages from P.195 - 226. Back to flying default 747 for a while i think. Thank you Peter. Corrie
