A missing hardware connection has been added to 3WF in order to also supply the lower GTN (650) with Baro Nav info, enabling VNAV (instead of just VCALC) on both GTNs, and also fixing a FPL sequencing issue on DPs like e.g. CBAIN ONE or NRVNA ONE with altitude-depending heading legs towards the first GPS waypoint.
All in-flight tests since that minor avionics surgery have been successful in 3WF:
- AP-coupled DP sequencing no longer hangs on altitude waypoints
- AP-coupled VNAV works fine
- AP-coupled missed approaches using the TO/GA button work as expected, i.e. the AP stays connected, establishes pitch up attitude and follows the FD on the missed approach sequence after the pilot confirms the corresponding dialog box
