SECTION 2 - SYSTEM DESCRIPTION
WARNING
Incorrect operation of this system could result in major damage to the system
or the aircraft itself. The cameraman must be briefed by the pilot and must
agree responsibility for operation of the system controls.
2.1. A nose-mounted moving camera system specified under modification MC-338 is
available for fitment to Cavalon Pro gyroplanes, and has been approved by UK CAA under
AAN29428 Addendum 2. A proprietary gimbal system is mounted on a vertical slide fitted to
the front of the gyroplane. This gimbal system has three-degrees-of-freedom and enables
the camera mounted inside it to be moved:
360 degrees in horizontal rotation (continuous) around a vertical axis
210 degrees in vertical rotation around a horizontal axis
+/- 45 degrees in roll
The camera itself has motorised zoom and focus capability.
The whole gimbal arrangement, internal camera and control console is supplied by Dynamic
Perspective GmbH as the DynaX5 gyro-stabilised camera platform. Various Broadcast-
quality and Cine-quality camera options are supported by the Dynamic Perspective
platform.
Externally-mounted gimbal Console carried inside cockpit
2.2. In order that the field of view of the camera is not interrupted by the aircraft nose-wheel
the gimbal system is mounted on the vertical sliding mount attached to the front of the
aircraft. This slide is pneumatically powered and its movement is controlled by two
conventional gas-struts. These gas struts also provide emergency lifting capability in the
event of pneumatic system failure.

Document number RSUK0370
Addendum 1_POH_Cavalon Pro Revision 1.0 – Issue Date 27 04 2016 2 - 2
A schematic of the sliding mount is shown below:
The mount is normally moved up/down by the pilot using a rotary valve mounted on the
instrument panel to the left of the aircraft’s centre console. In the event of pneumatic system
failure the air pressure can be released by means of a toggle-operated valve and the mount
will then rise under power from the gas-struts alone. To show the pilot that the gimbal is in
the lowered (filming) position a green LED is provided. There is no need for an indicator for
the retracted (landing) position as the gimbal mounting moves into the pilot’s field-of-view.
2.3. In order to provide compressed-air for the pneumatic system an electrically-driven
compressor, air-drier and 0.8bar pressure switch are fitted into a single pneumatic control
box. This box also contains adjustable flow-control valves used to control the air cylinder
speed (these are set during system commissioning and should not be disturbed). Electrical
supply to this control box is provided from the “Aux” circuit-breaker F19 (10A) which is
controlled by the aircraft master-switch and the load-shedding relay arrangement. Interface
is by means of a polarised connector mounted in the wall of the control box.
2.4. In order to provide 12VDC electrical supply for the gimbal/camera system a specific
cable is run from the battery (at the rear of the aircraft) to the left of the instrument panel
where a toggle switch is provided. This cable has a 40A line fuse (located near to the
battery). No warning lights are provided.
Note: it is the camera operator’s responsibility to place the gimbal in the nominated “Park”
position before the vertical slide is operated for take-off or landing - no interlocking is
provided.
2.5. The gimbal and turret are held in the nominated “Park” position by the action of internal
servo-motors, so the system must be powered-up at all times the aircraft is moving on the
ground or in the air, otherwise the components may droop or rotate uncontrollably.

SECTION 3 – PRE-FLIGHT CHECKS
WARNING
These additional pre-flight checks must be carried-out in addition to the
aircraft’s Daily/Pre-flight inspection as defined in the body of POH RSUK0334
3.1. Visually inspect the vertical slide system structure for cracks, broken welds or other
damage. Check the body interface for cracks and security of mounting (6-places)
3.2. Visually inspect the slide-system pipework for cuts, bursts and security of attachment
3.3. Visually inspect the gimbal/camera system cables for damage, breaks and security of
attachment
3.4. Visually inspect the (unheated) pitot tube for straightness and security of flexible
pipework. Remove any temporary closure protecting the pitot-tube.
NB: this (unheated) pitot tube may only be used in Day-VFR conditions and is not approved
for Night-VFR use.
3.5. Clean the visible surfaces of the slide-way rails with a soft cloth or tissue moistened
with thin oil or WD40. Inspect for damage to the rails, there must be no dents (e.g. from
flying object damage) or accumulated debris.
3.6. Clean the visible surface of the cylinder rod and gas-strut rods with a dry soft cloth.
There must be no damage or accumulated debris.
3.7. Check for free movement of the rod-end bearings of the gas-struts (4-places)
3.8. Using two people lift the nose-wheel of the gyroplane onto a suitable block at least
300mm high. Apply the parking brakes.
3.9. Significant electrical power is now required so either a high-current ground-power
connection should be made or the checks must be conducted with the engine running. In
the former case temporarily release the Gen1 and Gen2 circuit breakers. In the latter case
the pilot must occupy the P1 seat and appropriate safety precautions MUST be established
and observed.
WARNING
When the system is being moved on the ground ensure that both the operator
and any third-parties cannot be trapped by the moving parts
3.10. Using the toggle switch turn on the gimbal/camera supply. Follow the Dynamic
Perspective operating instructions to establish/confirm the default “Park” position

Addendum 1_POH_Cavalon Pro Revision 1.0 – Issue Date 27 04 2016 3 - 2
3.11. Turn on the aircraft master switch and listen for the compressor running to establish
system pressure. Ensure that the toggle-operated valve is set to “Closed”. Select the rotary
valve to “Down” - the slide system should move slowly (about 18secs) to the down position.
Select the rotary valve to “Up” – the slide system should move slowly to the up (retracted)
position (about 10secs).
3.12 Return the system to the “Down” position then test the emergency lifting mechanism by
changing the toggle valve to the “Open” position – the slide system should lift to the “Up”
position. If satisfactory revert to the standard operating arrangement by setting the rotary
valve to “Up” position then the toggle-operated valve to “Closed” – there should be no
movement but the compressor may be heard running.
3.13 Position the slide system to the “Down” position and carry-out the system checks
required by the Dynamic Perspective operating instructions.
3.14 Follow the Dynamic Perspective operating instructions to establish the default “Park”
position then lift the slide system by selecting the rotary valve to “Up”
3.15 Stop the engine (if running) and turn off the master switch. Disconnect ground power (if
fitted). Reset all circuit-breakers. Lift the gyroplane off the raising block and remove this
from the gyroplanes path.

SECTION 4 - FLIGHT CONTROLS AND LIMITATIONS
4.1. Pitch control is affected only by the additional nose weight and intuitive compensation
by greater aft stick movement.
4.2. Roll control is not noticeably affected by the installation.
4.3. Yaw control is affected by the installation as air-flow passing around and through the
turret “steers” the nose of the aircraft. However, intuitive compensation can be made within
normal control limits.
4.4. With the modification installed the aircraft’s Vne (Never exceed speed) is reduced to
75KIAS. Other notable speeds are unchanged:
V
ADesign manoeuvring speed 75KIAS
V
BDesign speed for maximum gust intensity 20-70KIAS
V
HMaximum level-flight speed at maximum continuous power 75KIAS
V
Hmin Minimum level-flight speed 25KIAS
4.5. Reference airspeeds for safe operation are unchanged:
Climb....................................................................................................60 KIAS
Best rate of climb / best endurance.......................................................50 KIAS
Best range............................................................................................60 KIAS
Approach.........................................................................................50-55 KIAS
4.6 Take-off distance is increased and landing data remains unchanged:
Take-off roll...................................................................................... 80 – 120 m
Take-off distance (560Kg MTOW)............................................................ 602 m
Landing roll.......................................................................................... 0 – 20 m
Landing distance from a 15m obstacle at 560Kg and 45KIAS.................. 200 m
4.7 Climb rate.
Climb rate with the camera fitted, and at 560Kg MTOW, is reduced to 500fpm.
4.8 Sink rate and glide ratio.
The drag from the camera gimbal will increase the rate of descent at 50kts by around
150fpm

Addendum 1_POH_Cavalon Pro Revision 1.0 – Issue Date 27 04 2016 5 - 2
4.9 Day VFR limitation.
The pitot fitted to the gimbal mounting is unheated, meaning the aircraft does not carry
the required equipment for night flight. So with the camera gimbal mounting fitted the
aircraft is only approved for day VFR operation.
SECTION 5 – ENVIRONMENTAL LIMITATIONS
5.1. The environmental limitations are unchanged, excepting in that the camera gimbal must
be operated within the limitations contained within the manufacturers instruction.

Addendum 1_POH_Cavalon Pro Revision 1.0 – Issue Date 27 04 2016 6 - 1
SECTION 6 - WEIGHT AND BALANCE
6.1. Installation of the system (total system weight 38kg) has a significant impact on the
aircraft empty weight and its centre-of-gravity. As part of approval under AAN29428
Addendum 2 the maximum take-off weight is unchanged (560kg). However, the longitudinal
centre-of gravity forward limit has been revised and is now 590mm forward of the datum
Under AAN29428 Addendum 2 the CG limits are therefore:
In x 345 to 590mm forward of the datum
In z 750 to 940mm above the datum
NOTE
If the aircraft is loaded and operated as described in POH RSUK0334 and this
Addendum 1 (RSUK0370), then these limits will not be exceeded

Addendum 1_POH_Cavalon Pro Revision 1.0 – Issue Date 27 04 2016 7 - 1
SECTION 7 – FLIGHT OPERATIONS
7.1. General
The gimbal system should be powered-up in the nominated “Park” position and the slide
system in the “Up” position at all times other than when manoeuvring for filming
7.2. Taxi
Taxi slowly and avoid as far as possible inclines, pot-holes, etc. Cross thresholds at an
angle to avoid the nose dropping and the gimbal contacting the ground.
7.3. Take-off
No noticeable change in technique, noting that the aircraft flies off in a flatter attitude.
7.4. Climb
No noticeable change in technique
7.5. Cruise
No noticeable change in technique
7.6. Manoeuvering (during filming)
Prior to filming the slide system should be lowered (and the “Down” position LED
illuminated) by means of the rotary valve. Control of the gimbal/camera is considered the
responsibility of the cameraman while the pilot manoeuvres the aircraft as required.
On conclusion of filming the cameraman will park the gimbal and request that the slide
system is raised and visually confirmed.
7.7. Approach
No noticeable change in technique, however as part of the pre-landing checks visually
confirm that the slide system is “Up”
7.8. Landing
Landing has a flatter attitude. Landing very slowly with a high nose up attitude tends to
result in a faster nose drop, potentially damaging the gimbal.
7.9. After landing
No noticeable change in technique
Maintain power to the gimbal/camera system until the aircraft has been parked and the
engine switched off
WARNING
AutoGyro GmbH and RotorSport UK Ltd have used their best endeavours to
design a safe and reliable gimbal support system. It is the operators
responsibility to ensure the system is properly functioning and without defects
prior to use, and neither AutoGyro GmbH or RotorSport UK Ltd take any
responsibility for any gimbal or camera damage in use whilst fitted to the
Cavalon Pro.
