AMC 1 ACNS.C.PBN.565 Transitions ED Decision 2019/011/R Transitions from one source of VNAV to another should not cause discontinuities or transients that have the potential to destabilise the aircraft on final or missed approach. Aspects to consider when transitioning from one source to the other include: (a) temperature errors, particularly if operating outside the allowable BARO-VNAV temperature range; (b) MSL versus WGS-84 ellipsoid for path definition; (c) curved BARO-VNAV path versus straight SBAS/GNSS path; and (d) linear BARO-VNAV guidance versus angular SBAS/GNSS guidance.
