I have following questions regarding b777 on
GPS
ADS B
ADS C
FMCF
Q1) With a complete GPS failure, ADS-B is lost (as per QRH) . Is ADS-C also lost?
ADS-C features various contract events which are independent of ADS-B operation. So is ADS-C avail with GPS inop?!
Q2) our MEL says - The Automatic Dependent Surveillance - Contract (ADS-C) Function is hosted in the FMCF
If there is DUAL FMC failure (FMCF's to be more precise) can I say I have lost ADS-C?!
And what happens to ADS-B when both FMCF's fail?
THANKYOU and regards
