Hi,

Recently I've been playing around with some settings in the PMDG 737, and I tried to get the engine option/N1 callout, at which R-TO, R-CLB, etc. is indicated on the Engine display instead of TO 1/D-TO 1, etc.
Now, the way I see it, is that this should quite simply change if you disable "double derate", as according to the PMDG FCOM 2.

"[Option - without double derate] Thrust mode display annunciations are: • R-TO – reduced takeoff • R-CLB – reduced climb • TO – takeoff" (page 325).

However, the only difference I've seen by doing this is so that only 26k and 24k (in the -800) are selectable options in the FMC, which is correct, however the N1 is still displayed as D-TO (or equivalent) if I select a derate/assumed temp.

 

My question is, why is this, and what option do i need to change in order to change this so that it will display R-TO/R-CLB when I derate the thrust?

 

Thanks.

The R TO and R CLB are not modeled. I am assuming the format is just an airline option. They are aware of the difference.
