Under particular conditions (hot-heavy-full thrust) the EGT can get very close to the limit during the takeoff roll, and at times exceed it.
Should this happen between V1 and 400ft, there's a time period of about 15 seconds during which the EGT stays above the limit, before doing the appropriate recall items.
After such an occurence, do you have any sort of guidelines about
continuing the flight to destination, or
returning to the point of departure?
Example: CFM56 3C1, EGT stays at 940° for 15 seconds.
Using common sense, one could say that a few degrees above max won't harm the engines, besides shortening their long term life, but...
How can you really know?
Is it still safe to fly like that? What if instead of 940° you reached 960°?
I've requested to our technicians their tolerance charts, hope they will not forget...
Thak you.
