I challenge anyone who are using the "what if an engineer walks in front" argument to close their eyes, look away and spend more then a second finding both masters.... At the end of the day your motor memory will find the location of the switch and know exactly where they are.
If the n2 >50%, you are correct that the start will not abort. Don't get an abort confused with a FADEC Automatic recover, designed to mitigate hot and hung starts.
<50% N2, the FADEC will abort start if required. Have a look at your EGT after 50% n2. There is only a very small increase in EGT ,relative to the start prior up to that point, and reduces quite quickly there after.
Using internal schedules the FADEC should know prior to 50% N2 whether the engine will overheat. If >50% n2 the engine exceed redline on a normal clean start, there is an issue with the engine and needs to be check by engineering.
Dont worry about the overtemp.
