Airplane and System
Description
7.13 Electrical system
The airplane is equipped with 14
V
DC electrical installation. A
generator with power of 250 W is the primary source of electrical
energy. The secondary source of energy is the accumulator
12V/16Ah that is located in the engine compartment on the firewall.
It is used for engine starting and in case of generator failure as an
emergency source of energy and also serves as the smoothing filter
of power system.
Widely equipped airplanes (night VFR, IFR) are fitted with the
auxiliary generator SD-20, mounted on the engine.
DC voltage is distributed to individual systems by main busbar.
Each system is protected by circuit breaker. If overloading of any of
the circuits occurs, then the circuit breaker is pulled out. Circuit
beakers are listed in the Aircraft Maintenance and Inspection
Procedures.
CAUTION
DO NOT USE CIRCUIT BREAKERS FOR
