ELECTRICAL LOAD DISTRIBUTION
1. DESCRIPTION AND OPERATION
The electrical system of the airplane is of a single-wire type, DC. It works with a voltage of 14 V and
the minus pole on the airframe. The electrical energy is distributed to the individual systems by the
main busbar and by the avionics busbar. Each of the systems is protected by the permanently
switched on circuit breaker. If any of the circuits is overloaded, than the circuit is disconnected by the
circuit breaker.
A. Switches
The switches serve for switching on / off of individual electrical circuits. Each of the switches is
labelled with the circuit specification. The switches are located on the left side of the instrument
panel.
MASTER SWITCH
Switches on / off the electrical network
Switches on / off the avionics power supply
Switches on / off the turn indicator
HORIZON
Switches on / off the attitude horizon
Switches on / off the directional gyro
BEACONS
Switches on / off the strobe lights
POS. LIGHTS
Switches on / off the position lights
Switches on / off the landing light
Switches on / off the electrical fuel pump
IC
Switches on / off the intercom
Switches on / off the 12 V socket power supply
