Fuel leak from engine : N1/N2 Indications
One question that I hope can be answered in a simple way.
According to flight crew training manuals and QRH , one of the possible indications of an engine fuel leak is decreasing N1 indications (low pressure compressor and rotor speed ) However if there a fuel leak I expected the problem to be apparent first on N2 ( high pressure compressor ) , since the result of the combustion is to first drive the HP compressor .
Am I getting something wrong here ?
