Hello ,

This is not strictly a v2500 engine question but i thought this would be an appropriate thread to post in .


Ok my question is the Flex is used for derating right . For eg i am not taking a huge load , i dont want the engines reving to their max limits so i " fool " the engine control in to thinking the outside air temperature is more so the thrust is reduced . Now what if i dial in a lower temperature ? like if the OAT is 35degrees and i put in 15 degrees .

1) will the engine control deliver a thrust that is available at 15 deg oat ? ( seems unlikely The physics of a gas turbine wont allow it.)

2) Or will may be try and fail and in the process may be cause damage to the engine ?

3) Figure out i am being stupid and give a warning may be ?

I understand each aircraft may have their own implementations but i am curious what the Airbus does and the IAE engine types.

Thanks.
