Feature List
  • New Features 
  • The RealAir Spitfire 2008 package is brimming with innovative features, many completely new for FSX. These include:
  • The Merlin-powered Mark IX and XVI are included in addition to the Mark XIV.
  • New and improved VCs, designed from the ground up for FSX with new features including specular and bump mapping (See Cockpit page).
  • True 3D gauges with silky-smooth movement that are an additional improvement on our already acclaimed ‘Smooth Gauges’ (See 3D Gauges page).
  • New exterior models compiled specifically for FSX, with improved textures, new features such as bump mapping and specular mapping, and many new liveries (See Spitfire Mk IX and Spitfire Mk XIV pages).
  • Improved sounds for both the Merlin and Griffon Engines with realistic stereo and doppler effects. These sounds have been designed to really capture the famous Spitfire sound.
  • New camera views in the VC (See Cockpit page).
  • Advanced flight modeling with numerous new features (See Flight Dynamics page).
  • High-quality 32bit textures are now available as an option. (Requires an additional download). Features carried over from the FS2004 version 
  • Visible and audible pre and post stall buffeting.
  • Overstress sound effects.
  • Realistic engine torque effects.
  • Engine failure simulation, causing complete engine failure if engine limits are exceeded.
  • Visible oil splatter on the fuselage and windscreen following an engine failure.
  • Custom scenery, including AI Spitfires, of RAF West Malling in Kent, UK, circa 1944.

Spitfire Mk 9X

Included in this package is the legendary Rolls Royce Merlin engined Mark IX Spitfire in addition to our established Mark XIV powered by the Griffon Engine. The Mark IX Spitfire came about chiefly as a result of the need to compete with the Focke Wulf Fw 190 which in some regards could out-perform and out-climb previous Spitfire versions. 

The Mark IX was based on the Mark V airframe with the addition of the new generation of Merlin engines which had a two stage automatic supercharger, auto-mixture control and, at full power, the Merlin 66 was capable of 1,720 hp and gave the Mark IX elliptical winged aircraft a ceiling of 43,000 feet in its standard form. This was known as the LF. Mark IX and in standard specification had just two quite small centrally placed fuel tanks forward of the cockpit bulkhead. 

The total number of Mark IX (and variants) produced was 5,665, more than any other Mark. The basic LF Mark IX represented by RealAir’s simulation had a fixed tail wheel, unlike the later Mark XIV which had a retractable tail wheel. We have also recreated the clipped winged version of the Mark IX which had a slightly greater roll rate and better low altitude performance, but could not match the high altitude performance of the elliptical winged Spitfire. 

We have included one Mk XVI (16) livery in this package. The Mk XVI was essentially the same aircraft as the Mk IX except it was powered by a Merlin licence-built by Packard in the USA. Both the Rolls Royce Merlin in the IX and the Packard Merlin in the XVI had essentially the same power output and identical handling characteritics. 

The liveries represented in our Mark IX were first flown after 1943 and although some of these variants might have at some time had features and additions beyond the standard Mark IX specifications, all of our aircraft use the Merlin 66 and standard fuel tanks.

Spitfire Mk X9V

The Mk XIV was powered by the Rolls-Royce Griffon rather than the Rolls-Royce Merlin of the preceding marks. The Griffon had a much larger capacity than the Merlin - 36 litres versus 27 litres - this gave it significantly more power than the Merlin. One aspect of the Griffon that caught-out many inexperienced pilots was the fact that the propeller rotated in the opposite direction to the Merlin’s propeller, and as such the effects of torque and P-factor were reversed. On takeoff, instead of swinging to the left the Mk XIV would swing to the right, and the massive torque from the larger capacity and 5-blade prop meant rudder was insufficient to counter the swing if full power was applied. 

In this package there are four variations of the Mk XIV to choose from: 

Elliptical Wing: This is the classic WW2 variant of the Mk XIV, featuring the Spitfire’s famous elliptical wings and standard five-blade propeller. 

Clipped Wing: This version is representative of the operational Mark XIV shorter wing-span variant that was intended to operate at lower altitudes. It has a quicker roll rate, higher dive speed and lower service ceiling, but in other respects it is similar to the elliptical wing variant. 

Contra-Prop Prototype: From the outset the Griffon-engined Spitfires (including the Mk XIV) had handling problems brought about by the massive torque of the 36L Rolls-Royce Griffon and its associated five-blade propeller. This was partly offset by the broader-chord fin and rudder introduced on the Mk XIV, but stability problems persisted. The contra-rotating propeller featured two propellers rotating in opposite directions thereby providing neutral prop torque. However, the contra-prop never made it onto an operational Mk XIV due to consistent, catastrophic gearbox failures on test aircraft. You may find it much easier at first to fly this version since you will not need rudder to correct the drift on take off. 

Racer: This is a fictional version with phenomenal power (3000hp) and higher max. boost. While this is not based on a real aircraft, it is representative of the type flown in the world famous Reno pylon races, and ‘real world’ Rolls-Royce Griffons have been tuned to produce upwards of 3000hp in racing aircraft of the past, such as the famous ‘Red Baron’ RB-51 Mustang. Being fitted with a contra-prop there is no swing /torque effect to deal with and you can throw this version around pylons, or you can fly it around the normal FSX scenery for very quick sightseeing trips

Flight Dynamics

New Flight Dynamic Features in the FSX Spitfire

We have redesigned the flight dynamics of both the Mark XIV and Mark IX for this version of the Spitfire. With a new and more controllable side slipping feature, you can bleed off speed and height with more finesse compared to the FS2004 version. The spinning routine has been refined and you can now continue a spin, once established, with full rudder and neutral elevator, or with a little up-trim keep the spin going with neutral rudder and full back elevator. 

You will find the elevator control more finely graduated and the pitch control is now easier and more refined for landing. Please note that trim is calibrated for the trim slider set at the midway point in your control settings in FSX. 

The new flight model is capable of a high speed, or high G, stall which means you now have to be more cautious with high fuel loads when using large elevator deflection in high or low speed turns. In normal operation you should not exceed 6 positive G and beware of stall onset (indicated by buffeting) with high G turns at speeds less than 200 knots.

Cockpits

The virtual cockpits in this version of the RealAir Spitfire are completely new. Improvements have been made to the shape of the 3D objects, making them smoother and more realistic in appearance. This improvement extends to most areas of the cockpit, but one area where it is particularly noticable is the windscreen-frame, the frames have smooth, rounded curves and each bolt is individually modeled in 3D. When viewing the screenshots take a look at the door-latch mechanism, which you will notice is smoothly modeled in 3D right down to the latch spring. The textures are also much improved with the inclusion of specular mapping and bump mapping. Thanks to this the VC surfaces come alive as you roll and pitch the aircraft, as the sunlight glints off different shapes and surfaces. 

Also included are multiple cockpit versions - the Mk IX and Mk XIV feature different cockpits, plus there are both heavily worn WW2 era cockpits, and clean 'restored' cockpits in both marks. Additonally the Mk XIV racer versions feature modern primary instruments and off-white or blue-grey interior paint. 

With the combination of clean cockpits, dirty cockpits, gunsight equipped cockpits, radio equipped cockpits, and cockpits with modern instruments and colours, there is an unprecedented variety of virtual cockpits to fly from in this package.

3D gauges

Like all our FSX aircraft, the Spitfire VC now includes true three-dimesnional gauges with silky smooth movement. These gauges remain true to life no matter the viewing angle or lighting conditions.

Included scenery

Within this Spitfire Package is some specially made scenery depicting West Malling, a real RAF Wartime Station located in Kent, South Eastern England, about 25 miles from the centre of London. 

West Malling was one of the most important fighter aircraft stations in Southern England between 1940 and 1945. For most of WW2 West Malling housed various squadrons of Spitfires and was most notable as a base from which Mk XIV Spitfires attempted to sabotage German V bombs by tipping their winglets before they reached their target... generally London. West Malling also had active conventional fighter squadrons. 

The scenery, created by Bill Womack, depicts the airfield as it was circa 1943, with several hangers, workshops, a tower, shelters, officers quarters, stores, and the ad hoc “blister hangers” in which the Spitfires would be temporarily housed before they were scrambled. West Malling has a 4000 ft runway (06/24) and an unused grass strip traversing it
