Why is no consideration given to the use of VNAV, geometrical vertical path angles coded in the navigation database?
Prior to U7.1, vertical angles from the data base were not used by the FMC to calculate the VNAV path, since VNAV disconnected when flaps were extended beyond 15 degrees, and VNAV was not certified for approach operations. Beginning with U7.1, navigation data base vertical angles are included in VNAV descent path construction if coded by the navigation data base supplier. The vertical angle is flown into the waypoint, which is typically the runway for approaches. Since the angle is flown into the waypoint, there may be a short level segment after the FAF, until the vertical angle is intercepted. On U7.1 and later FMCs, VNAV is certified for approach operations and remains valid for all flap settings. Boeing is currently in the process of developing a nonprecision approach procedure which will utilize VNAV to track these vertical path angles for the 737NG.
