OF
SYSTEMS
8.1 Ignition
System
8.1.1 Supply
The CDI Unit receive their supply via duplicated feeds from the aircraft bus bar (2 x 1 amps
circuit breakers).
8.1.2 Triggering
Two steps in the rim of the flywheel, nominally 180° apart, inductive fixed timing sensors.
8.1.3 Ignition
The spark plug pair are fired simultaneously, each by its own coil, triggered by the output from
the CDI unit. Each ignition switch interrupts the supply to its coil.
8.1.4 H.T.
Leads
The inductive H.T. coils are connected to the spark plugs by copper–cored cable and resistive
plug caps.
8.1.5 Spark
plugs
The specified spark plug type must be used; substitution with a non–approved type may
reduce engine power and reliability, and may cause mechanical damage to the engine.
8.2 Generator
System
A flywheel mounted 18 amp brushless / bearing less generator, with a separate voltage control
regulator / rectifier unit, provides 14 volt DC supply to the aircraft bus bar.
8.3 Starter
The starter is an electric starter operated with 12 V, 50 A. It is of a Bendix Type, engaging the
gear when operated (refer to drawing no. R1A-90-000-000).
