depending on what aircraft you are flying
Well the thread title said 777
If you look at the emergency turn off 30R ... you could well be below 400ft when you are required to turn
Don't wanna sound sarcastic ... but are you sure? Post the EO SID for DXB so we can see!
I am lucky I don't have to deal with derate only ATM…..so I can push the thrust levers fully forward
Sure from one point of view ... but one day you might need to use Fixed Derate to increase your maximum allowable takeoff gross weight (not possible with ATM) ...
