18.5K derate N1 limit


Recommended Posts

Hello!

When I select 18.5K derate it gives 87.5% N1 limit on sea level and 15c temp. On takeoff the A/T spools the engines up to around 85.1% N1 and stays there (which means ~17k thrust). Should the engines spool up to 87.5% N1 when TO/GA button is pressed?

Yeah, I had hoped that this would be fixed with another fix I made, but it is still there...I added it to the bug-tracker.

For now you can circumvent this by pulling out the "manual N1" knobs and setting them to the required N1.

Cheers, Jan

 

Could you please explain how to use manual N1 setting?

On my side if I manually set 75% N1 I finally have 84% N1 after pressing TOGA button.
