I am talking about a normal take off with two engines. Your perfromance from runway analysis are bases on a flap retraction altitude of 1000 AGL of course taking into consideration one engine out.

Now considering a normal take off with two engines , for some reasons you decide to reduce thrust at 800 AGL ( noise abatement, fuel saving policy etc..)

Should an engine fail at that moment? Are you protected? Because the performance calculated on the runway analysis are based on a flap retraction altitude of 1000 so they assume take off thrust until at least flaps retraction altitude.
Your max weight , assumed temperature , all lmitations calculated are based on a take off thrust until 1000.
So if you take off with 2 engines and decide to reduce thrust at 800 are you protected or is it legal?
