Thank you for the comment. As far as I know learned from other sources, entering FLAPS setting without entering CG in CDU displays V speeds. I believe V speeds is independent of CG value. 1. Entering FLAPS setting in the CDU => FMC calculates V speeds and displays on the CDU. (CG is still empty box) 2. Entering CG in the CDU => FMC displays stabilizer takeoff TRIM setting. V speeds do not update due to entering CG. CDU in PMDG 777 needs both FLAPS setting and CG value to get V speeds. I would like to confirm whether entering CG is mandatory to get V speeds. Thank you, Tetsuji Konohira

Currrently, it looks like PMDG 777 requires entry of CG to get takeoff V speeds. According to the PMDG 777 FCOM, entry of CG calculates stabilizer takeoff setting. It does not say entry of CG is required for takeoff V speeds calculation. Is this a bug ?
