FMC Thrust LIM

Recommended Posts

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

Fully loaded and full of fuel = over t/o weight !

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?

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 ?

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.
