For the project I am working on TOGA thrust on an ISA day is about 104/108% N1. CLB thrust in the upper flight levels can be around 103%N1 and TOGA/MCT in the mid flight levels around 110%.
From what I can see so far I am unable to get the engines to achieve an N1 higher than 100% even when I have the correct N2_N1 tables inserted along with the below settings inserted into the engines.cfg.
What you can also see is the engine is making the correct rated thrust but at 100% N1 which of course should not be the case if TOGA is supposed to be 106%.
The knock on effect of this is climb and CRZ performance is substantially off and the engine can't reached the correct rated CLB or takeoff thrust setting.
Also if I set the above CFG settings to lower than 100% N1 then they are respected and the engines won't go over the set N1 limit so long as it's lower than 100% N1.
Steps to reproduce:
- Select a Jet engine and set the high_n1= high_n2 max_n1_protection max_n2_protection to values of more than 100% or copy the settings I used above.
- Set weather to ISA and no wind at sea level airport.
- Increase power to TOGA and you will see a slight N1 overshoot to say 101% but it will slowly come back to 100% and you should see that at 101% it's creating over the max rated thrust.
Tested on both SU5 and SU6
