Vertical Speed Mode; To Operate In The Vs Mode; To Initiate A Climb Or Descent From Altitude Hold Mode - Honeywell KAP 140 Installation Manual

System Operating Modes
PITCH functions available with autopilot engaged
Vertical Speed (VS) Mode
The Vertical Speed (VS) mode allows variable vertical speed climbs and descents.
The ALT button toggles between Altitude Hold (ALT) and Vertical Speed (VS) modes.
Note: The KAP 140 engages into VS mode as a default.
To operate in the VS mode (with autopilot currently disengaged):
1. Engage autopilot – Press and hold AP for 0.25 seconds to engage the autopilot.
Note ROL, VS and current vertical speed is displayed. If no other modes are selected the
autopilot will operate in the ROL and vertical speed hold modes.
2. UP or DN button – Select desired climb or descent rate. Each button stroke will
increment the vertical speed commanded up or down by 100 ft/min per button press, or at
the rate of approximately 300 ft/min per second if held continuously.
To initiate a climb or descent from Altitude Hold (ALT) mode:
1. ALT button - Press. Note ALT changes to VS and current vertical speed is displayed.
2. UP or DN button – Select desired climb or descent rate. Each button stroke will
increment the vertical speed commanded up or down by 100 ft/min per button press, or at
the rate of approximately 300 ft/min per second if held continuously.
Note: When operating at or near the best rate of climb airspeed, at climb power settings,
and using vertical speed hold, it is easy to decelerate to an airspeed where continued
decreases in airspeed will result in a reduced rate of climb. Continued operation in vertical
speed mode can result in a stall.
