SUPERMARINE SPITFIRE F Mk 22 for FS2004/FSX
============================================
This is a model of a Spitfire F Mk 22 of No 73 Squadron, Ta Kali, Malta in 1948.

Spitfire F.22
==============
There was so little difference between the F.21 and F.22 that the allocation of a new mark number was barely necessary. This difference in designation has been explained as necessary to cover the change of voltage in the electrical systems of the respective versions which were 12 volt for F.2l and 24 volt for F.22, but in fact, as already related, late production F.21's had 24-volt instrumentation. It has also been said that one of the main differences between this mark and the following F.24 was that the latter had additional fuel tanks in the rear fuselage. In fact, early production F.22's had a rear fuselage tank fitted, but its use was officially prohibited. The Mk22 had a rear view fuselage with a redesigned hood. Later models with Spiteful type fins and larger tailplanes, had more obvious differences.
Production, from March 2lst, 1945, was concurrent with the F.21. 627 were ordered, but only 260 were built. No prototype was involved. Spiteful type fins and rudders were introduced during production. Handling trials with a 3 X 500 lb. bomb load were carried out at the A. & AE.E. early in 1947 on PK408 and this armament was intended for squadrons overseas. No. 73 Squadron used F.22's at Ta Kali, Malta until 1948. These were PK380' D', PK391, PK397 'H', PK5l8 'F', PK544 'C', PK555 'K', PK556 'R', PK572 , N', PK576, PK594 , J', PK607' Q', PK6ll 'B', PK6l2, PK656 'E', PK662 'V' and PK674 'L'. They were some of the few F.22's to see first-line service, they were marked only with individual letters, as unit code letters were not used post-war by No. 73 Squadron. The majority of F.22's served in Auxiliary Air Force squadrons, but a few, as late as 1951 were used at Flying Refresher Schools, examples are PK340 MA3, PK499 M.37 and PK620 M.35 of No. 102 F.R.S.
Although not declared obsolete until May 1955, it was little used after 1952, by which time most surviving examples, some 80, were in storage. lt did, however, have a new lease of life in other services; 22 (including PK355, PK401, PK482, PK486, PK494, PK562, PK575, PK594, PK668 and PK672) were delivered in two batches of 11 to the Southern Rhodesian Air Force (now the Royal Rhodesian Air Force under the Central African Federation) where they were serialled SR58-68 and SR79-89. Twenty reconditioned F.22's were sold to Egypt in 1950 and 10 to Syria.

Detail Data
As per Mk. 21 except that maximum permissible loading was 11,350 Ib. and length was 32 fI. 11 iD. The similarity of the F.21 and F.22 was so close that both had the same Works No., Type 356. However, the cut-down rear-view fuselage common to the type, with the deletion of the rear-view mirror as no longer necessary, increased the maximum speed by 1 m.p.h.
Power Units and Airscrews: Rolls-Royce Griffon 61 driving a five-bladed constant-speed Rotol, Type R5J5F5J2, airscrew witt Jablo or Hydulignum blades or Griffon 85 driving two three-bladed contra-rotating Rotol airscrews.
-Armament: 4 X 20 mm. British Hispano Mk. II
cannons witt 175 r.p.g. inboard and 150 r.p.g. outboard.
-Dimensions: Span 36 fi. Il in., length 32 fi. 8 in., wing area of 243.6 sq. fi.
-Weights: Empty 7,160 lb., normal loaded 9,900 lb. (wing loading then 40'5lb. per sq. ft.), maximum permissible (with 170 gallon drop tank) 11,290 lb.
-Performance: Maximum speed at 19,000 ft. 450 m.p.h., at 25,000 ft. 449 m.p.h., sea level 390 m.p.h. Maximum rate of climb 4,900 ft. peI' min. Service ceiling 43,000 ft. Range (normal) 580 miles at 230 m.p.h. at 20,000 fi. (with 70 galls. drop tank) 965 miles. Maximum diving speed 520 m.p.h.
-Tankage: Two tanks situated one above the other forward of the cockpit with capacities of 36 galls. (upper) and 48 galls. (lower). Two tanks situated in the leading edge of each wing with capacities of 121 galls. (inboard) and 51 galls. (outboard), giving a total fixed capacity of 120 galls. Long-range drop tanks of 30, 45, 90 or 170 galls. could be carried. The oïl tank of 9 galls. capacity with 3 galls. air space, was situated forward of the upper front fuselage tank.


Installation:
==============
-Unzip "Spit22" into a temporary file and move the "Spit22" folder into the main Aircraft directory.
-Attention...the panel.cfg files are different for FSX and FS2004.
-For FSX,change the FSXpanel.cfg into panel.cfg and let it replace the first one.
For FS2004,change the FS9panel.cfg into panel.cfg and let it replace the first one.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-Read instructions carefully when installing the gauges, say YES...when asked if the gauges sources should be trusted. If you say no....some of the gauges are not going to work !
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-Leave the "fighters" map in your panel folder.
-Copy the effects into the Microsoft Games\Flight Simulator X\effects folder and the 20can.wave in the Microsoft Games\Flight Simulator X\sound folder.
ATTENTION :
-For FS2004, change the FS9_Wing_Guns.fx into FX_Wing_Guns
-For FSX change the FSX_Wing_Guns.fx into FX_Wing_Guns
NOTE: If you have trouble with the canopy and prop transparancies when flying with Acceleration, replace the the glass.bmp and 5bladeprop.bmp with those in the "acceleration map".

Effects
--------
-On startup there is automatic engine smoke.
-Then follow the exhaust flames with smoke.
-Wing vortex effect appears by default at 2.5g or quick roll rate.
-Continuous blue flames with smoke if engine is running .
-You have WAR emergency power with the WEP gauge.
-Contrails from 20,000 ft.
-Wing cannon with flash, smoke and falling cartridges can be triggered with the standard Strobe key (O).
It is much nicer however if you put the FS2004 standard Strobe key (O) to the trigger from your joystick.You can change this in the Key menu.
It is a good idea if you replace the standard (L) key for lights by the L+CTRL, (normaly activating the landing lights only). This avoids you having to have all lights on when pulling the trigger.

Flying the model
================
This plane is a dream to fly scale aerobatics with. It is a non critical but very powerful and precise flying machine.
-Cockpit door is used with the spoiler key.
-CTRL+E opens the canopy
-Radiator flaps are opened/closed by the close cowl key.
TAKE-OFF :if you have manual rudder enabled, be ready to apply hard LEFT 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 LEFT rudder, brake to keep the aircraft straight.
4.Take off at about 100 Knots, wheels and flaps up at 130 Knots.
5.To fire guns activate O-key or trigger.
6.Approach at 25% flaps, wheels down at 120 Knots.
7.Touchdown at 85-90 Knots.
Like with the real plane, much use of elevator trim will be needed.
