Throttle and brake quadrant
The throttle and brake quadrant with choke is located on the left side of the pilot station.
Throttle control (1) is conventional with IDLE in aft (or pulled) and full throttle in most
forward position. With the ROTAX 914 UL engine the boost range is entered by overcoming
a small resistance to the front. The throttle lever is linked with cable controls to the
carburettors. A mechanical spring applies tension to the control cables and brings the
carburettors to full throttle in case of a cable break. The throttle lever has a pre-set friction
brake which holds the throttle in the selected position.
Choke (3) is used start a cold engine. In
order to do so, pull the choke lever fully to
the rear or ON position and be sure to
have the throttle in idle position. After
starting the engine and a short warm-up,
the choke can be slowly disengaged by
moving the lever into its forward or OFF
position.
The hydraulic wheel brake is actuated by
pulling the brake lever (2). A locking pawl
mechanism allows setting for use as
parking brake. In order to release the
parking brake pull the brake lever a little
further to let the spring-loaded locking pawl
disengage, and then release wheel brake.
Do not try to disengage the locking pawl by
pressing the small release lever without
pulling the brake lever at the same time.
Releasing the pawl using the small release
lever only will lead to premature
deterioration of the teeth. If the teeth are
worn the function of the parking brake will
be compromised!
The throttle and brake quadrant also
supports the brake fluid reservoir (4) with
screw cap and fluid level minimum and
maximum markings, as well as the primary
brake cylinder (5).
Brake fluid is DOT4.
The rear cockpit is may be fitted with a throttle and brake lever for instructor use.
The rear cockpit may also be fitted with magneto cut-off switches.
