2.5 USER CONTROLS

2.5.1 PANEL BUTTONS

All flavors of the FCC are functional subsets of the full--featured system FCC. Therefore, the
description of functions for the high--end FCC also applies to lower--level systems containing the
same feature. The full--featured flavor of the FCC provides the following pushbuttons:
Switch Function
AP Couples Autopilot in default modes. Required before engaging all other modes
in --xxx3 versions and above.
HDG Engages/disengages Heading Select mode
NAV Engages/disengages arm/tracking of VOR , GPS (Enroute) or Localizer
APR Engages/disengages arm/tracking of VOR (Approach) , GPS (Approach) or ILS
(with GS)
REV Engages/disengages Reverse Localizer (Backcourse) tracking
ALT Engages/disengages Altitude Hold
ARM Engages/disengages Altitude Arm mode.
BARO Momentarily allows use of rotary knobs to adjust the baro--setting. If held for more
than 2.0 seconds, toggles baro units between hPa and in Hg.

2.5.3 ROTARY KNOBS
The rotary knobs provide control of the Selected Altitude. The outer knob changes Selected
Altitude by 1000 foot steps. The inner knob changes Selected Altitude by 100 foot steps.
If remote baro--correction is not selected, the rotary knobs can also be used to enter
baro--correction. For 3.0 seconds after pressing the BARO pushbutton and for an additional 3.0
seconds following any subsequent rotary knob movement, the numeric display will show the
present baro correction and the rotary knobs will adjust the baro--setting instead of Selected
Altitude. In this mode, the outer knob will change the baro--setting by 0.1 in Hg or 10 hPa. The
inner knob will change the baro--setting by .01 in Hg or 1 hPa.
