Electronic

The Electronic Panel controls the internal electricity of all aircraft systems. The electric power can be supplied either by means of the Main Generator, the Standby-Gen., the EPU or the Batteries. Using power from the batteries, supplies electricity only for the minimum requirements. The standby Gen. Provides energy only to the main systems. The Main Gen. Powers ALL systems and circuits. This panel is located on the left console.

ElementTypePositionInformation
MAIN PWR3-Way switchMAIN PWRConnects external power or the main generator to the electrical system and enables standby generator. Determines function of FLCS PWR TEST switch. If ac power is not available, connects aircraft battery to the battery buses.
BATTConnects aircaft battery to the battery buses, disconnects main generator or external power, resets main generator, disables standby generator and determines function on FLCS PWR TEST switch.
OFFFlight: Disconnects main generator from electrical system and disables standby generator.
Ground: Disconnects all main generator or external power from the aircraft electrical system and disables standby generator. Disconnects the aircraft battery from the battery buses. Canopy operation and FLCS battery trickle charge are available after engine shutdown.
CAUTION RESETButton-Resets ELEC SYS caution light and clears MASTER CAUTION light for future indications. Resets main and standby generators. Resets overload protection unit for the nonessential ac bus and the nacelle ac bus.
Status light2-Status light
(amber)
FLCS PMGFlight: FLCS PMG is not supplying power to any FLCS branch.
Ground: FLCS PMG power is not available at one or more FLCS branches. Light is delayed 60 seconds after initial NLG WOW.
MAIN GENIndicates that external power or main generator not connected to one or both nonessential ac buses.

EPU GENIndicates the EPU has been commanded on but the EPU generator is not providing power to both essential ac buses. The light will not function with the EPU switch in OFF (WOW) and the engine is running.
EPU PMGIndicates the EPU has been commanded on but EPU PMG power is not available to all branches of the FLCS.
ACFT BATT2-Status light
(amber)
TO FLCSFlight: Indicates battery bus is supplying power to one or more FLCS branches and voltage is 25V or less.
Ground: Indicates battery bus is supplying power to one or more FLCS branches.
FLCS RLYIndicates that voltage on one or more of the four FLCC branches connected to the aircraft battery is inadequate (below 20V) or that one or more FLCS branches are not connected to the battery.
ACFT BATTStatus light
(amber)
FAILFlight: Indicates aircraft battery failure (20V or less).
Ground: Indicates aircraft battery or battery charger failure. Light in delayed 60 seconds after MLG WOW.
