B777 eec
To correct myself:
In the acft that i fly the red line shows the mechanical limit of 98.6% therefore the overspeed limit, the N1 target is computed by the EEC based on the selection made on FCP - TO, MCT, CLB, CRZ and APR - and affected by environmental conditions, density altitude, bleed air configuration and usage of wing/cown anti-icing: when the AT is engaged the AT will command the target N1 only in takeoff/go around mode or in FLC mode adjusting the pitch to maitain the selected speed while in PITCH mode and in VS mode will adjust the thrust levers so as to maintain the bugged speed for the selected pitch.
Now i am wondering if i can overboost my engines since i have always been taught that i can if needed advance the thrust levers to the limit of 98.6% or even more for a very short time.
The N2 target can be exceeded without any time limit.
What kind of indication would i have if i overboost the engine?
Many thanks
