Spitfire XI



FS2002/Fs2004/FSX Spitfire XI: The Mk XI was a reconnaissance aircraft based on a combination of features from the marks VII, VIII and IX. The cameras, two vertically-mounted and sometimes an oblique mounted one, were installed in the fuselage behind the cockpit. The first Mk XIs were built in November 1942 and lasted until 1944 when they were phased out in favour of the Mk 19. The PR.XI was chronologically well ahead of the PR.X, being derived from the Mk IX. Powered by a Merlin 70, it could climb to 44,000 ft (13,420 m) and attain a speed of 422 mph (679 km/h). The only Mk IX derivative to have a retractable tailwheel, the PR.XI had the broad chord rudder; an enlarged oil tank like all PR variants; and the same leading-edge fuel tanks in the wings pioneered by the PR.IV, bringing the total fuel capacity up to 228 Imp gals (1,036 litres). Deliveries commenced in late 1942, early aircraft being powered by the Merlin 60 series engine. The PR.Mk.XI variant, the last one of the Spitfires with Merlin engine, was the most important allied reconnaissance airplane in the European front, being used by the RAF and the USAF flying missions alone and unarmed at distant objectives like Berlin.

Speed and range records: The Spitfire Mk. XI flown by Sqn. Ldr. Martindale,attained the highest ever speed for a Spitfire on his flight on 27 April 1944. He achieved a true airspeed of 606 mph. During the spring of 1944 high speed diving trials were being performed at Farnborough to investigate the handling of aircraft at near the sound barrier. Because it had the highest limiting Mach number of any aircraft at that time, a Spitfire XI was chosen to take part in these trials. It was during these trials that EN 409, flown by Squadron Leader Martindale, reached 606 mph (Mach 0.89) in a 45 degree dive. Unfortunately the aircraft could not cope with this speed and the propeller and reduction gear broke off. Martindale successfully glided the twenty miles back to the airfield and landed safely.

With the outbreak of World War II, many Argentinians flew as volunteers with the RAF to fight against Germany. Among them was captain James Storey, who brought a Spitfire Mk XI from England after the war to use it for aerial mapping tasks. It had an enormous fuel tank fitted under the fuselage, to make the passage of the Atlantic, becoming the first machine of this type that arrived in Argentina. The Vickers-Armstrong company did a general maintenance service, installed additional fuel tanks and equipped the airplane with three Williamson F.24 f.8 (2 verticals and 1 oblique) cameras. It departed to Buenos Aires on 29 April 1947 at 10,50 hours from Hurn, England. The airplane had been constructed in 1944 (matriculation PL-972) and only had 20 flight hours. The stages of the flight were Gibraltar, Dakar, Natal, Rio de Janeiro, Montevideo and Buenos Aires. Storey had to make a forced landing in Africa in the heat of desert, due to very bad weather that lasted several days. The airplane was equipped for this long trip only with a VHF radio. Owing to the lack of other air-navigation instruments, the passage of the ocean was made accompanying an Avro York of British South American Airways (BSAA), who offered to guide him above the ocean. The modified Spit had a fuel capacity of 315 gallons, augmented by two additional tanks of 20 gallons in the wings and one of 170 gallons under the fuselage, which was equivalent to more than 10 hours of autonomy at an economic cruise speed of 400 km/h, that is about 4,000 km of range without reserves. The crossing of the Atlantic demanded 8 hours 30 minutes.



-On startup there is automatic engine smoke.
-Then follow the exhaust flames with smoke.
-Continuous blue flames with smoke if engine is running .
-You have WAR emergency power with the WEP gauge.
-Wing vortex effect appears by default at 2.5g or quick roll rate .
-At 20,000ft condensation trails appear.

-Unzip " Spitfire11" into a temporary file and move the "Spitfire11" folder into the main Aircraft directory.
-Attention...the panel.cfg files are different for FS2004 and FSX. 

-For FS2004,change the FS9panel.cfg into panel.cfg and let it replace the first one. The stickhand, throttlehand and panoramic view only work in FS2004.
-For FSX,change the FSXpanel.cfg into panel.cfg and let it replace the first one.
-Read instructions carefully when installing the spitfire_mki.gau ,  say YES...when asked if the gauges sources should be trusted. If you say no....most of the gauges are not going to work !
-Leave the Spitful map , MkI Spit Stick.gau  and  MkI Spit Throttle.gau. in your panel folder. These 2 gauges may be removed for FSX.
-Put the spitfire_mki.gau  into your  Microsoft GamesFlight Simulator Xgauges folder.
-Copy the effects into the   Microsoft GamesFlight Simulator Xeffects folder.

Flying the model
This plane is a fair, non critical but very powerful flying machine.
-Spoiler opens cockpitdoors
-CTRL+E opens the canopy
-Radiator flaps are opened by the close cowl key.
TAKE-OFF :if you have manual rudder enabled, be ready to apply right rudder and brake when you hit the throttle !
Better apply throttle proportionaly and slowly at first.
1.Parking brake on, start engine, 1/4 flaps
2.Disengage parking brake
3.Hold enough rudder, brake to keep the aircraft straight
4.Take off at about 100 Knots, let speed build up, as the plane at first sinks back to the ground, wheels and flaps up at 130 Knots.
5.Approach at 25% flaps, wheels down at 120 Knots.
6.Touchdown at 70-80 Knots. 
Like with the real plane, much use of elevator trim will be needed.

In FS2004  you have mirror backview and you can take nice reconnaissance pictures from this plane. The SimIcons1024 Other Controls Icon, gives you a panoramic view with altitude and speed coordinates so you can take nice pictures from the scenery beneath. Just touch your stick viewknob to return to the 2D panel.
I didn't find a way to make these gadgets work in FSX, any hints are most welcome.
