EPR/N1 at thrust HOLD during takeoff run

[alex98 13]

Set Override to NEVER and did a quick test. I advanced the throttle to the programmed N1 setting. Problem still there. TO N1 was 105,5%, went to 107,5% before setting back to normal at 400ft (GE variant).

Any clue?

Thanks

Are you absolutely sure your 747 is up to date? Have you checked the version number in the Operations Center? It should be 3.00.8466.

Hi James,

Positive. Product up-to-date. I see in the changelog that panelstates prior to the last update (october) should be removed. I use one that I created prior to the last update. Could that be the reason? I will make a new one out of the default. And lets see what happens.

Thanks

Best regards

Could be.

Something is messed up on your system.

In which direction should I look to correct this? What could cause this?

I did another try with the GE variant. At 80 KT, increase in TAT associated with an increase of N1 until 400' AGL. Then N1 decreases back to the green target.
