HELLO

 i flight with fsairline, and as you know we have a tracker for overspeed limit with penalties

. my problem is when i take off, whatever what have programmed, the aircraft take off like a rocket to reach at least 270 kt, and then comes back down to the speed i asked for (in the FMC sp/limit like 245/100,for example or on the speed button ). but it s too late for the tracker ! i did an overspeed! could you help ?

1. Derate the T/O thrust even further.

 

or

 

2. Set a lower speed restriction below 10.000 ft (like 235 kts).

 

 

 

1. seems more RW to me.   :rolleyes:

HI 

thank's for your answer. but what do you call RW ? and how we derate further ?

but what do you call RW ?

 

Real World

 

 

 

and how we derate further ?

 

The tutorial explains how to do everything you are having difficulties with.  Please fly it.  You'll learn a lot from it.

RW = real world

 

If the TO-2 thrust is still too high you have to derate via the assumed outside temperature entered in the CDU to lower max thrust even further.

 

 

 

EDIT:

 

I'm waaayyy slower than Kyle!

OK 

Thank you all. i have read and watch the tutorial 1. and i made some flights already.but that subject isn't that crystal clear..

anyway tank you.

To be precise, you cannot derate it via assumed temperature.

I don't understand your post. If you are doing a takeoff on a 25C day and enter 35 or 45 as the assumed temperature you could think of the two temeraures as TO-3 and TO-4. Derate and assumed temperature both reduce thrust. So what's the difference?

Actually I wasn't referring to derating reduced thrust but to derating instead of using reduced thrust to accomplish lower thrust settings.
