No laggy computers and chunky motion seats here: Boultbee Flight Academy was after realism for its Spitfire Mk IX flight simulator. They even used a real Spitfire chassis. However, they lacked high resolution imagery and the ability to project it onto a spherical dome screen to simulate what a pilot would see and experience when flying this fighter plane.
Enter Optoma projectors, in concert with various other tech.
Boultbee Flight Academy, at Goodwood Aerodrome in Chichester, UK, is the world’s first Spitfire training school since the iconic fighter plane was taken out of operational service in 1955. In addition to its pilot training, the academy also offers real flying experiences to the public in various vintage aircraft.
The team, led by Boultbee Flight Academy, included Airtech Simulation Ltd. for overall simulator design, modifications of gauges, controls and instruments and preparation of the Spitfire fuselage and simulation software; Warpalizer Norway AS for the optical design of the projection systems including the Warpalizer warp and blend software; Fibresports Ltd. for the spherical dome screen and Optoma projectors.
Why Optoma Projectors Worked So Well
The simulator was installed in a 3.4 x 4 x 2.9m (WxDxH) room adjacent to the pilots’ briefing room. The 3.2 m radius spherical dome screen needed to be manufactured in bespoke segments to allow installation with minimum clearance in the height and width domains.
Seven Optoma W505 projectors with short throw 0.8:1 lenses were positioned and oriented so the images covered the spherical screen completely and, also very importantly, such that the Spitfire Mk IX fuselage, with its canopy closed, did not create any shadows on the screen.
Olav Sandnes, the CEO of Warpalizer Norway AS, says, “Despite the non-ideal positioning of the Optoma projectors, the Optoma W505 offered an acceptable focus across the screen and the 0.8:1 lens ensured sufficient overlapping of the images which provided excellent blending.”
“The unique design gives an angular resolution of three arc minutes per pixel across the screen.”
To ensure a seamless and geometrically correct visual system, the Warpalizer software was integrated integrated with Prepar3D v4 simulation platform.
Further enhancement of visual quality was achieved by running the 5,000-lumen Optoma W505 projectors in Eco mode, thereby also extending the life time of the lamps.
The 3D scenery projected includes a geo-specific model of the Goodwood area and surroundings, allowing the simulator training to resemble real flights as much as possible.
The fuselage used is a section of a real Spitfire Mk IX. All of the controls, gauges and instruments are real, but modified for realistic, in-flight behavior.
Boultbee Breaks a Record
The new Spitfire simulator at Boultbee Flight Academy’s main facility at Goodwood Aerodrome is said to be the most true-to-life Spitfire flight simulator ever built.
Thanks to its compact design, the simulator offers a horizontal field of view of 225° and a vertical field of view from -55° and to 110° (20° beyond north). The field of views offered by the projection system gives the pilot 100% coverage of the areas visible from his eye-point with the cockpit closed.
Matt Jones, MD & Chief Pilot at Boultbee Flight Academy, says, “It has been our plan for long time to commission a training simulator for our Spitfire war birds here at Goodwood Aerodrome. It gives a good feeling to experience that the performance of the simulator is even better than we expected and we are confident that the simulator will be an invaluable tool during the training of future Spitfire pilots.”

“It is also our intention to offer simulators flights to the public and to everybody that has an interest in preserving the finest British fighter plane every built.”
“Being a former air force officer myself, I have taken personal pride in the project and I hope to be able to see Spitfire fighter planes in the air and listen to the legendary Rolls Royce Merlin engines for many years to come.”
