FCU (Provides autopilot functions)

Note

Some functions are not available on S-TEC 55 Autopilot (Cessna 172 G530 model).

AP: Engages or disengages the autopilot system.
FD: Not available on S-TEC 55 Autopilot model. Provides visual cues for manual flight control based on autopilot logic without actually controlling the aircraft.
HDG: Heading mode. Autopilot turns the aircraft to heading selected via Heading Bug knob.
ALT: Altitude mode holds the current altitude.
NAV: Directs aircraft heading according to flight plan programmed into GPS (GPS mode) or to/from a radio navigation aid (VLOC mode).
VNAV: Not available on S-TEC 55 Autopilot model. Manages aircraft's vertical path according to a predefined route or waypoint altitudes.
APR: Activates an Instrument Landing System (ILS) approach mode for precision guidance during landing approaches.
REV/BC: Engages mode for flying an ILS localiser back-course approach, used for approaches where the aircraft is flying away from the beacon.
VS: Vertical speed mode to maintain an ascent or descent rate.
FLC: Not available on S-TEC 55 Autopilot model. Maintains a set airspeed while climbing or descending to a selected altitude.

Radio (ADF, COM/NAV functions)

ADF FREQ: Displays ADF frequency and ADF standby frequency. Pressing button will swap frequencies.
COM 1: Displays COM1 frequency and COM1 standby frequency. Pressing button will swap frequencies.
VLOC 1: Displays NAV1 frequency and NAV1 standby frequency. Pressing button will swap frequencies.

Engine (Displays engine data)

ENG RPM: Displays engine/prop RPM.
MANIFOLD PRESSURE: Displays manifold pressure.
OIL TEMP: Displays oil temperature.
OIL PRESSURE: Displays oil pressure.
FUEL FLOW: Display fuel flow in GPH.

CHT: Displays cylinder head temp in celsius.
BATTERY:
Displays battery charge in watts per hour.
Displays battery amps (negative value means battery is discharging)
THROTTLE: Displays throttle as a percentage.
FUEL EST: Provides an estimate on fuel remaining in hours, based on current fuel flow.
Formula: fuel_flow_kg_sec[0]} 3 roundn 0.000001 + / 3600 / 1 roundn
MIXTURE: Displays fuel mixture as a percentage.

Pedestal (Flaps, gear)

THROTTLE: Displays throttle as a percentage.
TOGGLE BRAKES: Displays the state of the parking brake. Push will toggle parking brake on/off.
MIXTURE: Displays fuel mixture as a percentage.
FLAPS UP: Extends flaps one notch.
