Airbus NPA managed and discontinued approach

[vilas]

This is the latest change. Basically when vertical guidance is provided by the system the approach is flown with FDs. Only for NPAs without vertical guidance TRK/FPA is to be used. This is better because with vertical guidance you fly the approach like the ILS.
and with this some terminologies have also come like APV=approach procedure with vertical guidance, RNAV(GNSS) using LNAV/VNAV minimum, BaroVNAV Barometric Vertical Navigation:FMS computed vertical guidance based on Barometric altitude. ABAS= airborne based augmentation system(GPS+IRS).
About discontinued approach it is surprising that it has taken so many years and possibly some messed up go rounds to formalise a procedure. It is not easy to suddenly think a way out when asked to go round when clean because all missed approach training is imparted when configured for the approach. So now there is no mystery. You know what is the problem and what will happen and the course of actions.
