[RESOLVED] JPT Limiter not working

[lukeXIII]

With JPTL on, the engine fuel system should reduce rpms as the short wet/dry limits are met (NFM-000 11.9.2 JPT Limiter). However this is currently not working, rpm is not being limited (outside of normal rpm limits) and the JPT can exceed limits.

Hi @lukeXIII,

 

You are absolutely right that when the JPT limits are met, the fuel systems automatically reduces RPM when the limit is exceeded. However in the picture above the current JPT is 810ºC and the JPT limit is 821ºC. So in this situation there is no need for the engine to reduce the RPM because the MAX JPT is not exceeded.

 

If you have a track that shows what you are describing please attach it so we can analize it.

Short lift dry/wet JPT limits are 780 and 800 degrees respectively, which can only be sustained for 15 seconds. In the above example (dry conditions) the temperature is 808 degrees, so the limit has been exceeded by 28 degrees. 

 

"Max JPT" seen in the ENG page is just a record of what temperature the engine has reached, it is not a limit.

Hi @lukeXIII,

 

It seems that an entire overhaul on engine and indications have been performed already fixing this issue and other ones. They should come on the next update.

Hi, as said above, could you tests this issue after the next Harrier update ?

 

Thanks

[lukeXIII]

Tested after latest openbeta update, issue still exists. Only tested with dry conditions as there seems to be something wrong with the wet JPT.

Hi again, the issue has been fixed and should be available next update.

Hey guys, is this still an issue ?

[Wisky]

for me its working fine in game. 

 

but if you select manual fuel on and jptl off it will jptl at 710°. dont think it should do that

Hi,

 

Thanks for the confirmation, could you do a new bug report highlighting this issue ?

 

Moving this to resolved, thanks :).
