However, if the rating used is -10%, for example, and a FLEX TO is based on that -10% value, then you can only safely advance to the -10% rating. If you go to full nameplate rating then all bets are off
Barit1, could you please explain when you say the "rating" used? I'm sorry I just don't see exactly what you mean. Do you mean the rating of the engine as in set by the manufacturer? Where do you set the thrust levers to set the -10% rating?
If I flex on my current type(A320) or used T01/T02 on Boeing and engine failure after V1, assuming say a non-limiting runway, I always assumed you could either leave thrust at selected flex/derate or advance to TOGA(admittedly more to do with attaining screen heights and climb out).
Cheers
