MILVIZ DHC2 Beaver
Honeywell KAP 140 Autopilot system
(Sources: Honeywell KAP 140 Pilot's guide – Honeywell KAP 140 Installation Manual)
The KAP 140 Autopilot System included in the Beaver is a rate based digital autopilot
system offering smooth performance and enhanced features found only in more expensive
autopilots. The first of its type developed by Honeywell, this system brings digital
technology and reliability into the light aircraft cockpit.
KAP 140 roll axis features include wing leveler, heading select and VOR/LOC intercept
and tracking. The KAP 140 can also be coupled to GPS and RNAV receivers as well. Roll
rate information is derived from the turn coordinator.
Pitch axis features include vertical speed, glideslope and altitude hold along with altitude
preselect option. Pitch information is derived from a pressure sensor and accelerometer.
The KAP 140 Autopilot System operates independent of the aircraft's artificial horizon.
Therefore, the autopilot retains roll stabilization and all vertical modes in the event of
vacuum system failure.
