Hello 172driver,
The FCOM2 states that N1 and N2 overspeed protection is provided both in normal and alternate mode.
In normal and SOFT alternate mode ,that would be correct.
However in HARD alternate mode,there is no engine compressor speed protection anymore,only engine turbine protection via the overspeed governor.
My question is in case of HARD Alternate mode,what would be possible actions to avoid a compressor overspeed/EGT over temp in hot days conditions.



Thanks for your input.
