2.4 KC 140 FCC

2.4.1 GENERAL DESCRIPTION
The FCC accepts mode selections from its panel buttons and cockpit switches and provides mode
and failure annunciations for the system. It also uses sensor inputs to calculate commands for
the servo actuators. Pilot control of the mode reference is also provided for Vertical Speed and
Altitude Hold modes. The FCC is available in several versions: roll--stabilizer with heading and
NAV, two--axis (pitch and roll) without preselect, and two--axis with altitude preselect. The two--axis
systems include autotrim and Manual Electric Trim functions as an option. Pilot control of the mode
reference is provided for Vertical Speed and Altitude Hold modes. The two--axis FCCs include a
normal accelerometer and static pressure sensor for vertical modes. In systems with altitude
preselect, the FCC uses a baro--correction input to provide optional selected altitude and altitude
alerting functions.
The FCC is designed to operate from 11.0VDC to 33VDC. A separate audio power input is used
for alerting functions. All backlighting illumination uses 5V incandescent bulbs for reliability.
Backlighting inputs are used as signal inputs and do not source illumination power to the unit. The
FCC is designed to operate in an ambient temperature from --40° C to +70° C.
