- The TakeOff (TOGA) thrust represents the maximum thrust available for
takeoff. It is certified for a maximum time of 10 minutes, in case of engine failure at
takeoff, or 5 minutes with all engines operative.
- The Go Around (TOGA) thrust is the maximum thrust available for goaround.
The time limits are the same as for takeoff.
- The Maximum Continuous Thrust (MCT) is the maximum thrust that can be
used unlimitedly in flight. It must be selected in case of engine failure, when TOGA
thrust is no longer allowed due to time limitation.
- The Climb (CL) thrust represents the maximum thrust available during the
climb phase to the cruise flight level. Note that the maximum climb thrust is greater
than the maximum cruise thrust available during the cruise phaseThe aircraft actual takeoff weight is often lower than the maximum
regulatory takeoff weight. Therefore, in certain cases, it is possible to takeoff at a
thrust less than the Maximum Takeoff Thrust. It is advantageous to adjust the thrust
to the actual weight, as it increases engine life and reliability, while reducing
maintenance and operating costs.
