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 quadrant also features the control for cabin heating / air conditioning system (4). All
controls are labelled correspondingly by engraved text and symbols on the cover plate.
7.11 Electrical System
The 12V DC electrical system consists of two engine driven electrical generators, a battery,
master switch, indicators, switches, electrical consumers, and cabling. With the ROTAX
915iS engine an electrical power supply is vital for continued engine operation as this
engine variant solely relies on electrically driven fuel pumps and engine ECU. GEN1 is used
by the engine only, GEN2 is used to supply the aircraft ancillary systems.
An additional, externally mounted 40A generator (Gen3) is optionally fitted to Cavalon
gyroplanes equipped for high electrical load operations.
Turning the master switch to the ON position closes the battery contact and energizes the
gyroplane’s electrical system. The red LOW VOLT warning light will illuminate as a
functional check. A steady indication, however, warns the pilot that the voltage of the
system has dropped below a safe value. In this case a safety circuit (load shedding relay)
will automatically disable the unnecessary systems (seat heating, 12V power receptacle,
heating fan).
Orange Gen3 (where fitted) warning light is installed to indicate that the battery is not being
charged by that generator.
Seat heating note
. The optional seat heat is actuated by depressing the rocker switch
between the seats to either (I) or (II) heat setting (with the switch centred for OFF). The
heater element is self regulating to that setting. The seat heating requires considerable
