pfft... it looks outboard of the surge tank, so a little left aileron trim and a little left rudder trim, or maybe just a little more N1 on engine 2, and we are good to go. Is the right wing even on the MEL?
Be careful doing that.....you don't want to ' melt ' you rear turbine blades ....!!
N1 is an indicator gauge which shows how ' hot ' things are in the rear turbine ( rear turbine temp *C ) ... keep it out of the ' RED ' Zone.
You're thinking of EGT.
On high-bypass turbofan engines N1 is the rotational speed of the fan-low pressure compressor-low pressure turbine spool, displayed as a percentage. For aircraft like the B777 in the picture the pilots uses N1 to set engine power since most of the thrust (maybe 80% or more) is generated by the fan which is part of this N1 spool. Take off, flex/derate, climb, cruise thrust are set using N1 values.
Low-bypass turbofans like the JT8Ds on the B727 used the EPR indicator for setting power, but you won't see many of them around anymore.
After 25 years in flight training for Ansett and Qantas I'm full of useless information like this.
I see what your saying EGT ( Exhaust Gas Temp )...............
It's true that Engine RPM is always expressed in % value ...80% RPM ...or whatever value is set.
N1 ( Engine RPM )...we considered that it was ' critical ' to be aware of the ' temp ' at the first stage of the rear turbine blades ( EGT )......if your pushing for higher RPM ( giving the engine more fuel ), equals more heat, more RPM and it all gets a lot hotter.
Your correct in your statement.

You're right, this is true. In general, during engine start EGT is monitored for conditions like a hot start. Also when in TOGA (takeoff/go around thrust) under certain conditions EGT may exceed limits.

MAN TOGA, SRS, RWY, AUTOTHRUST BLUE.....sigh..I do miss it sometimes.
Now retired, but I was on the second QF B747-4 to A380 conversion course. Sadly they'd canned the endorsements conduced in Toulouse a couple of months earlier.

Second conversion course, I'm guessing you had decent seniority.
Check/training Captain maybe?
I worked at Airport West, domestic fleet, so our paths probably didn't cross, I was only at Mascot when I was needed for meetings, although your name does sound somehow familiar.

now they can see what is needed to fix it.
