1. [ Description of this aircraft ]

The Short SA.4 "Sperrin" (named after the Sperrin Mountains, a range of hills in Northern Ireland) was a British jet bomber design of the early 1950s built by Short Brothers and Harland of Belfast, popularly abbreviated "Shorts".
It first flew in 1951.
Although it was not put into production because swept-wing designs such as the Vickers Valiant were by then available, the Sperrin prototypes were valuable for research data on large jet aircraft.

In the post-Second World War war period, the British authorities felt there was a need for an independent strategic bombing capability in other words that they should not be reliant upon the American Strategic Air Command.
In late 1948, the Air Ministry issued their Specification B.14/46 [1]for an advanced jet bomber that should be the equal of anything that either the Soviet Union or the Americans would have.
The exact requirements included a weight of 140,000 lb, the ability to fly to a target 1,739 miles distant at 500 knots from altitudes of 45,000-50,000 ft and be simple enough to maintain at overseas bases.
A further stipulation that a "special" in RAF jargon, a nuclear bomb, weighing 10,000 lb and measuring 30 ft (length) and ten ft (diameter) could be accommodated.

There had already been specification "B.35/46" the previous year for a "medium-range bomber landplane" that could carry a "10,000 pound [4,500 kilogram] bomb to a target 1,500 nautical miles [2,780 kilometers] from a base which may be anywhere in the world."[2]

The 1947 request anticipated that the fully laden weight would be under 100,000 lb (45.4 tonnes), the bomber have a cruising speed of 500 knots and that the service ceiling would be 50,000 feet (15,200 m).
This request would be the foundation of the V-bombers.

However the Air Ministry accepted that the request might prove to be beyond the reach of Britain's aircraft manufacturers and prepared for a fall-back position in the form of an earlier specification B.14/46 which was more conservative in its demands and under this they placed a contract for two flying prototypes and a static test machine with Shorts.

The design known initially as SA.4 and later as the "Sperrin" had more in common with the Second World War designs than the new jet age.
It was straight winged, although the leading edge was slightly swept.
The engines were mounted in nacelles mid-wing; two engines per wing with one engine stacked above the other.
The airframe was built largely of aluminium alloys with tricycle undercarriage.
The nose gear retracting backward and the main gear in the wings towards the fuselage.

The SA.4 was designed for a crew of five: pilot, copilot, bombardier, navigator and radio operator, though only the pilot had an ejection seat.

6. [ About the directions point in FS2004 and FSX]

This aircraft model is made by using FSDS Ver2.24.
Therefore, it is possible to play basically in FS2004(FS9) and FSX(FS10).
However........!!
In FS2004.
For a wide large-scale aircraft, the distortion is caused and the phenomenon of the aerofoil tip's disappearing happens in the spot shooting mode.
If this phenomenon happens, Please switch to the spot shooting mode by using other small aircraft.
Afterwards, if this aircraft is selected, it is normally displayed.

And........
In FSX.
Because gauges do not correspond to FSX, the gauges in the cockpit are not displayed.
Please you looks for a suitable gauges and setup Panel.cfg by yourself.
Sorry...............
