F-16 re FLEX Temp / AST method. A fictitious temperature is fed to ECU so that a reduced thurst is provided by the engine. This reduced thrust level is pre-calculated to provide exactly the amount of remaining thrust needed for the EFATO - Go case.
For the purpose of this thread, the HOW (Temp) is not relevant, also the De-Rate feature could be used (same goal). The WHAT is - for every takeoff a different thrust is used and thus a reference acceleration pattern is hard to define.
