You can overtemp and engine and you can overspeed an engine and both require logbook entries on every jet engine I have throttled. But overboost is a recip term and unfortunately it persists among even many training facilities.
And where this becomes a problem is when some training has the student figure a maximum N1 or Max EPR or whatever before doing a stall series. Rubbish, to use the term. Unless one considers stalls a normal procedure then normal limits do not apply. Firewall or MAX thrust until the thing quits shaking and the stall is broken.
I thought this concept of max EPR on recovery had been invalidated in the 80s with Air Florida 90 going into the Potomac but some still teach stalls in businessjets this way. ?????
