I have recently been flying a Bombardier CRJ 700 in a simulator and wondered how to derate the engines for takeoff.
I know how the takeoff thrust derating is selected in Airbus and modern Boeing aircraft via the (M)CDUs (see also How do pilots set the exact amount of thrust needed for a reduced power takeoff?) and I have also seen panels for setting engine modes including a flex temperature in aircraft like the MD-80 or the Avro RJ. However, I could not find anything like this on the CRJ (at least not in the simulator).
Can the CRJ even derate the thrust for takeoff? And if, how does it work?
I saw the thrust levers have detents labelled SHUT OFF, IDLE, CLIMB, TOGA, MAX POWER:
I assume TOGA would result in less thrust than MAX, but how is this selected?
