MD11 Engine Power is Lost when thrust is reduced on take off

Recommended Posts

Hi,

 

I recently bought the MD11 PMDG software.

 

I realized immediately that on take off, when the speed goes up rapidly, i reduce the thrust to adjust the speed. Just when i do that the power in the engines drops and then the engines don't respond at all; then go to idle.

 

Any thoughts as to why that may be happening?

 

Thanks

Are you still on the runway when you move the throttles back ?  Sounds like a RTO you are performing?

 

Are you arming the autothrottle before takeoff ?

 

Can you be more speciffic....I have no idea if you are in the air or not or if you have engaged any of the autoflight procedures.

Once you are on the runway and lined up for takeoff press the NAV, AUTO FLIGHT, and PROF buttons.  Advance the throttles so that N1 is somewhere between 70 to 75 percent. Let N1 stabilize in that range and make sure all three engines are at approximately the same N1. When stabilized, advance the throttles until you hear a click and see the message T/O Thrust in the upper right corner of the PFD. Don't touch the throttles again. The throttles are being controlled by the FMS. At 80 knots T/O Thrust should change to T/O Clamp. Rotate at VR.

I know with some joysticks you have to keep your trottle in the max position. If all is programmed well you should follow your FD and it will maintain the programmed speed.
