Hi,
I am trying to load a flight from VCBI (Colombo, Sri Lanka) to OMDB (Dubai, UAE) flying a United Airlines livery with Pratt & Whittney engines. After entering all the data into the CDU I can not get the FMC to calculate the V-speeds (no error message: V-speeds not available).
I than used a Lufthansa livery with GE engines, loaded the same panelstate, performed the same CDU input steps and the FMC calculated the V speeds.
On both aircraft the options are set to default and the option "FMC calculates V Speeds = YES".
I don't know what else to check
Thanks for help
