Dear folks
How come we enter the OAT into the FMC CDU during preflight of the Boeing 737-800?
I know one gets a reduced max thrust available if one doesn't.
Is it because the TAT-probe needs one pack functioning to give a correct readout to the ADIRU? But then again.. one would have ample time for OAT readings after startup and prior to T/O if this was the case.
