Automatic Vertical Speed Reduction at Altitude Capture
NOTE: Some installations allow a maximum of +/- 3000 FPM.
The example given below is for units limited to +/- 1600 FPM.
While in operate mode (ENT blank), the vertical speed commanded
will be automatically reduced as the aircraft approaches the selected alti-
tude in order to provide smooth altitude transitions from climbs and de-
scents to cruising flight. The vertical speed command will begin to auto-
matically diminish in 100 FPM increments at an altitude which will re-
sult in a 300 FPM vertical speed at the altitude capture. For example:
When climbing 800 FPM, to 6000 ft.:
At 5500 ft. the VS will diminish to 700 FPM
At 5600 ft. the VS will diminish to 600 FPM
At 5700 ft. the VS will diminish to 500 FPM
At 5800 ft. the VS will diminish to 400 FPM
At 5900 ft. the VS will diminish to 300 FPM - where it will remain
until altitude capture.
At the maximum climb or descent rate of 1600 FPM, the vertical
speed schedule will commence at an altitude error of 900 ft. where the
VS will diminish to 1100 FPM and continue to diminish at each 100 ft.
according to the previously outlined schedule.
NOTE: As a result of this automatic scheduling of closure rate,
the system will not accept high vertical speeds for small altitude
changes. For example, for a 500 ft. altitude change, the maxi-
mum selectable VS is 700 FPM.
