What is derated thrust?
The derated thrust method consists of reducing the engine’s rated thrust to a given level below full thrust. There may be one or more derate level on an engine. Therefore, the pilot should select one which provides enough thrust to takeoff.
What power do pilots have?
The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft. In an in-flight emergency requiring immediate action, the pilot in command may deviate from any rule of this part to the extent required to meet that emergency.
When to use low thrust or high thrust?
Typically, a low thrust setting is set to make sure all the engines are responding in the same way, and more importantly, will have uniform application of thrust thereafter. This can be done with (standing takeoff) or without the brakes on, 1 or during a rolling takeoff. Then it is TO/GA time.
What is the takeoff thrust limit for AC 25-13?
AC 25-13 S/4/88 rated takeoff thrust. Section 25.1521 requires that the takeoff thrust rating established for the airplane not exceed the takeoff thrust rating limits established for the engine under Part 33.
How many takeoff thrust does a turbojet engine have?
Rated takeoff thrust, for ‘a turbojet engine, is the approved engine thrust, under within the 0peratin.g limits established by the engine type certificate the minutes provisions for takeoff of Part operations. 33, and is limited to periods of not more than five (2) Takeoff thrust, for an takeoff thrust, established for setting that is
When to use an afterburner for a takeoff?
3.6.6 Make an afterburner takeoff anytime the computed MIL power takeoff roll exceeds 50 percent of the available runway. 3.7.2 For single ship takeoffs, if the single ship computed military power takeoff distance exceeds one-half of the available runway, takeoff using afterburner.
