[RAF] De Havilland Comet DH.106 2R

The De Havilland DH106 Comet was the world's first commercial jet airliner. Featuring four Rolls Royce Ghost engines cleanly integrated into the wing-root, a pressurised cabin and performance that surpassed its contemporaries, the Comet would initially see a successful career. A string of highly publicised disastrous crashes would lead to all Comets being withdrawn from service and grounded, with an extensive investigation being launched into the causes of these disasters.

After the conclusion of the investigation, De Havilland set about building an improved version of the first Comet, featuring improved range and performance through stronger Rolls Royce Avon engines, a slightly larger wing and higher fuel capacity. The hull was also lengthened to accommodate more passengers. Despite these improvements, all orders for the improved Comet 2 had been cancelled prior to its development in the wake of the 1954 investigation. All but four would eventually be allocated to 216 Squadron of the RAF Transport Command, where they would be designated Comet C2 and used in a variety of roles, ranging from charter flights, to troop transport, to VIP transport. Some would even be modified with specialised equipment to monitor Warsaw Pact signal traffic, carrying the designation 2R.


This particular aircraft is based on Comet 2R XM655 of Royal Air Force No.51 Squadron. Due to the lack of documentation and the fact that several relevant details may be classified to this day, the interior and functions of this aircraft are highly speculative. Accuracy is not guaranteed.

# Cold Start Procedure #

- (0) - Engaging the parking brake is advised, but not necessary.
- 1 - Disconnect ground utilities (Generators, refueling hoses, Airstairs)
- 2 - Set throttle to 2.
- 3 - Engage "Main Electronics" breaker.
- 4 - Activate "Fuel Cut-off" switch on Engine #1.
- 5 - Press and hold "Starter #1" until RPS reaches 0.5.
- 6 - Repeat steps 3-4 for the other engines.
- 7 - Engage "Flight Controls" breaker.
- 8 - Engage "Ammenities" breaker.
- 9 - Disengage Parking brake.

# Shutdown Procedure #
- 1 - Deactivate "Fuel Cut-off" switch on affected engine(s).
- 2 - Throttle down to 0
- 3 - Wait.

# Flaps #
! - Flaps do function, but require a high amount of throttle to avoid a stall. Use with caution - !

# Radar #
- 1 - Locate Breaker at the lower left corner of the Co-pilots instrument panel.
- 2 - Engage "Radar" breaker.

# ELINT Systems #
- 1 - Locate Fuseboxes at the rear end of the cabin.
- 2 - Access Breakers by opening Fuseboxes.
- 3 - Engage Breakers of systems needed for operations.
- 4 - Return to stations needed for operations.
- 5 - Operate stations.

# Sniffer Operations #
- As this system is not produced in-house, no instructions are readily available. For instructions, refer to the original manufacturer.


# Further Notes #
- This aircraft is, by default, flown from the co-pilot's position. A switch at the center of the instrument panel swaps control between the pilot and co-pilot position.
- This aircraft is capable of reaching the Arctic through careful fuel management and, should the weather be against, you, usage of the central fuel tank.
- Be careful when taking off. This aircraft is prone to tailstriking if you pull up too hard.
- The INS does not stop the aircraft from rolling. At least one pilot is to remain on station while flying.
- Disable INS before reaching exact waypoint coordinates. Failing to do so will result in the aircraft violently whirling itself around the exact point where the INS directs it to stay on that exact point. An auto-disable function is currently being developed.
- The lack of heating in the main cabin is intentional.
