operations. For some navigation systems and operations,
manual selection of scaling will be necessary.
2.
Pilots flying FMS equipped aircraft with barometric
vertical navigation (Baro-VNAV) may descend when the
aircraft is established on-course following FMS leg
transition to the next segment. Leg transition normally
occurs at the turn bisector for a fly-by waypoint (reference
paragraph 1-2-1 for more on waypoints). When using full
automation, pilots should monitor the aircraft to ensure the
aircraft is turning at appropriate lead times and
descending once established on-course.
3.
Pilots flying TSO-C129 navigation system equipped
aircraft without full automation should use normal lead
points to begin the turn. Pilots may descend when
established on-course on the next segment of the approach.
