7.2.4. Electrical
system
The design of the electrical system is based on the ASTM F2245 (design
specifications for LSA) requirements for night flight. Only high-quality wiring is used,
the cross-sections and insulation meet applicable aviation requirements.
The electrical system is based on a 12V, 7Ah lead-gel battery which is charged with a
maximum output of 250 Watt by a DC alternator integrated into the engine
compartment. This battery has very high performance and needs specific charging
procedure if discharged. If properly maintained it has a very long service life.
Power is distributed via a common power bus which the fuses and circuit breakers of
the individual instrument groups are directly connected. Power is then transferred to
the instruments and avionics using switches where necessary. All ground lines are
connected to the battery via a ground bus. The avionics are grounded separately
from the rest of the aircraft in order to avoid interference.
The layout of the electrical system is depicted in the following block diagrams. They
show the wiring layout and help to explain the function of the installation with respect
to power supply as well as the data interchange between the individual instruments.
Should more detailed schematic diagrams be required for maintenance purposes,
these can be requested from Flight Design.
