* Limit for 20 seconds maximum between 850 °C and 900 °C.
** The FADEC continuously sends to the avionics the maximum TRQ available
that depends on current airplane operation and current external conditions. The
upper boundary of the green arc is updated accordingly. This maximum available
TRQ is valid for all flight conditions.
