FLIGHT International, 9 December 1978 the final grass-field landing trials and, when an air- conditioning pack has been tested, will be refurbished and delivered to the IAF. Aeritalia is trying hard to extend sales of the G.222. The fitting of Rolls-Royce Tyne 20s in place of the 3,400 h.p. GE T64-P4DS will remove the US export embargoes which have been hampering Aeritalia salesmen. The first Tyne- powered G.222 is to fly during 1979 and a later version with stretched fuselage is contemplated. The G.222 has a num ber of attributes which make it readily exportable, includ ing pressurisation, ability to change roles quickly, full avionics, and good performance in hot-and-high conditions. Sales prospects are good enough, says Aeritalia, to warrant the expense of re-engining and recertification. Libya has been reported as the first customer, with an order for 20 worth $382 million, and India is a possible buyer. Dubai has bought one G.222 with T64s and the Argentine three. Dubai has one more on option. The fuselage of the G.222 is made at Naples, but the wing centre-section is contributed by Piaggio, the wing panels by Macchi, tail surfaces by Siai Marchetti and en gine nacelles by IAM (formely Saca). The T64s are pro duced by Alfa Romeo and Fiat, but the Tynes will prob ably be bought from Rolls-Royce. In its basic version the G.222 grosses 58,4001b, has a maximum payload of 19,8201b and tankage for 2,637 Imp gal. It can transport 11,0001b at 1,000ft for 515 n.m. and return without refuelling, or the same load at optimum cruising height for 1,480 n.m. or 3,0801b for 2,580 n.m. The cabin can accommodate 44 troops, 32 parachutists or 36 stretchers plus six people sitting. An 11,0001b load can be parachuted. The T64 engines are flat-rated to ISA + 20°C and give a take-off run of about 2,500ft at sea level in that temperature. G.222 in many guises Aeritalia has delivered two electronic reconnaissance conversions of the G.222 to the Italian Air Force. This air craft can remain airborne for six hours, carrying elaborate receiver equipment and ten console operators. Air con ditioning is provided. The standard G.222 carries nose radar, Doppler radar and navigation computer, a Collins autopilot and airways radio. Aeritalia also offers a civil flight inspection version of the G.222 equipped to calibrate VOR, Tacan, DME, NDR, Marker, PAR and radar beacon. A computer allows a single operator to do the calibration work. A jeep can be carried in the cabin to facilitate post-flight Work on the ground. The aircraft can be quickly reconverted for trans port. During 1977 Aeritalia proved the firefighting G.222, which carries a 4,0O01b pallet-mounted Sama water-dis charging kit. The pallet can be installed in two hours and loaded with 14,9601b of fire-retardant in eight minutes. Discharged at 120kt from 150ft, the retardant can lay a fire barrier 1,000ft long. The Sama kit brings gross weight to 58,3001b and radius of action is 200 miles. Finally, Aeritalia offers maritime patrol and VIP trans port versions with mission equipment mounted on re movable pallets. For air-sea rescue the droppable rescue equipment is housed in external containers. Tornado Italy originally took a 15 per cent share in Pan- avia and will buy 100 of the 805 Tornados to be built. For Italy Aeritalia is taking the lead in airframe work and Fiat in engine work, and about 100 companies are conr tributing to both development and production, in 30 cases as prime contractor. The accompanying tables indicate the principal companies and their contributions. Aeritalia itself is mainly responsible for the wing and has calculated and rig-tested the aerodynamic and dynamic loading of the wing, flaps, slats, pylons and external loads and the. trajectories of loads when launched or jettisoned. Aeritalia has assembled and flight-tested prototypes P.05 and P.09 and is about to fly pre-production Tornado P.14. P.05 made a hard landing in January 1976 but is now flying again. P.09 has spent much time at the Decimo Mannu test range in Sardinia checking flutter and the release of stores.
