7.17 Indicators and Sensors
Rotor speed is measured by a magnetic pick-up, located directly at the geared ring of the
rotor head. Rotor bearing temperature is measured by a temperature sensor which is glued
into the rotor bearing sleeve.
Other indicators and sensors have been described in the respective paragraphs. For engine
related indicators and sensors see the engine manufacturer’s manual.
7.18 Seats and Seatbelts
The seats consist of seating surface as an integral part of the monocoque structure and
adjustable backrest, upholstered with removable cushions. The cushions consist of a foam
core covered with an easily cleanable, water-repellent fabric (or leather).
The backrest hinges are positioned by 2 countersunk Allen bolts on two seating rails. To
suit to different leg lengths the backrest hinges can be adjusted by removing the Allen bolts
and refitting in a different position on the rails. In addition the backrest angle can be
adjusted by modifying the lengths of the telescopic tubes.
An adjustable four point harness is provided for each seat. Make sure that the seat belt is
buckled and tight when flying with the left hand seat unoccupied.
7.19 Stowage Capacity
A storage area is located behind each seat with a maximum capacity of 10 kg each.
7.20 Fire-warning system
The Cavalon Pro gyroplane is equipped with a Fire indicator light to alert the pilot that a
certain temperature in the rear equipment compartment or the engine compartment has
been exceeded, possibly as a result of a fire. The fire indication circuit is based on a special
cable routed inside the two compartments. The cable has two integrated wires separated by
an insulation layer. At a defined temperature the insulation layer will melt and the embedded
wires close contact.
A possible fire (circuit closed with low resistance) will be indicated by a flashing/blinking Fire
indicator light in the Warning and Caution Panel. During normal operation (circuit closed
with ‘normal’ resistance) the Fire indicator light will be off. A malfunction of the system
(circuit open or shorted to ground) is indicated by a constantly lit Fire indication. At every
power-on event the system will perform a lamp test consisting of a series of three flashes.
