\par
BACKGROUND\par
\par
The Hunter GA11 was an operational training aircraft operated by the Royal Navy from the early 1960's to the mid 1990s. More information can be found here: http://www.fradu-hunters.co.uk/index.html or here: http://www.thunder-and-lightnings.co.uk/hunter/survivors.html .\par
\par
The Royal Navy's GA11s were converted from surplus Royal Air Force F4s, and were given the distinctive saw-tooth wing leading edge of the F6 while retaining the lower-powered Rolls Royce Avon RA 7 giving about 7500lbs of thrust. The gun pack was removed, and an arrestor hook added (for airfield use only - the GA11 was not capable of carrier operations). This is the aircraft modelled.\par

CONTROLS\par
\par
The following additional keyboard controls have been implemented:\par
\par
\pard{\pntext\f1\'B7\tab}{\*\pn\pnlvlblt\pnf1\pnindent0{\pntxtb\'B7}}\nowidctlpar\fi-720\li720 [/]: extend/retract flaps in 10 degree steps.\par
{\pntext\f1\'B7\tab}F/f: canopy open/close\par
{\pntext\f1\'B7\tab}H/h: hook extend/retract (no operational function)\par
{\pntext\f1\'B7\tab}CTRL F: emergency flap lowering. Operation of this control gives a once-only lowering of the flaps to maximum. It disables the normal flap extension, and cannot be reversed.\par
{\pntext\f1\'B7\tab}CTRL B: toggle speed brake is implemented, and is interlocked with the undercarriage so that it cannot be extended while the latter is down. The reverse is not true (yet). There are 2 warning lights on the port instrument panel indicating the interaction of these 2 items.\par
{\pntext\f1\'B7\tab}'L/l/CTRL L: pilot's seat raise/lower/default setting.\par
{\pntext\f1\'B7\tab}Ctrl J: Jettison drop tanks. See NOTE 1\par
{\pntext\f1\'B7\tab}\par

\pard\nowidctlpar NOTE: \par
\par
1. This is a crude simulation at present. Jettisoning the fuel tanks only affects the tanks - the fuel they contain remains available. Gravity is not simulated - if you jettison while inverted the tanks will defy gravity rather than falling through the wings.\par

{\pntext\f1\'B7\tab}Altimeter: Knob - pressure setting\par
{\pntext\f1\'B7\tab}Undercarriage Selector - up/down\par
{\pntext\f1\'B7\tab}Flap Lever - Flap extend/retract in 10 deg steps\par

OPERATION\par
\par
Start-up.\par
\par
The model starts with engine running at ground idle, and with brakes ON.\par
\par
Take-off.\par
\par
Select 10 deg flap. Maximum take off power is 7950 rpm. (NOTE: the RPM instrument is of the clock type showing true RPM NOT %n1.) The model will swing to port as it accelerates. Use differential braking (,/.) to keep straight until about 100kts IAS when there is sufficient rudder authority. Rotate gently at about 150kts IAS. WARNING: there is a lot of aircraft behind the main wheels, and it is easy to impact the runway with the tail bumper.\par
\par
Flight.\par
\par
Pitch trim is heavily affected by power settings. You will need to adjust pitch trim constantly. The model is unstable in roll, and cannot be trimmed hands-off. Use the wing leveller.\par

ACKNOWLEDGEMENTS\par
\par
Thanks are due to:\par
\par
David Cooper who helped build the aircraft (the original, not the model),\par
Colin Newnes who flew the aircraft, and whose memory has been stretched to recall some obscure details,\par
Lee Elliott some of whose Seahawk model has found its way into this one, and\par
Jim Wilson, whose P51d instruments formed the basis of some of the Hunter instruments. \par
