10.Piper PA-36 Pawnee Brave Agricultural aircraft :-
Ans.
Piper announced in 1972 a completely new version of the PA-25 Pawnee agricultural aircraft which introduced a more powerful Continental Tiara 6-285 flat-six engine of 213kW, a new cantilever wing, new safety features, filtration of the air entering the pilot's ventilated and heated cockpit, and a larger standard chemical hopper of 0.85m3 or, optionally, 1.08m3 capacity. Designated Piper PA-36 Pawnee Brave, the new model began to enter service in 1973, and in 1977 an additional version with a 224kW Avco Lycoming IO-540-K1G5 engine became available, the designations of these two aircraft then becoming PA-36 Pawnee Brave 285 and PA-36 Pawnee Brave 300. In 1978 this latter aircraft became the standard model, a new PA-36 Pawnee Brave 375 being introduced with a 280kW Avco Lycoming IO-720-D1CD flat-eight engine, and equipped with the larger of the two chemical hoppers as standard. These were to remain in production with Piper until rights for both versions of the PA-36 were acquired by WTA Inc. in 1981. This latter company was marketing this agricultural aircraft in two versions, the version with the 280kW engine now being the basic model and redesignated PA-36 New Brave 375. It was available optionally with a 298kW IO-720-D1C engine under the designation PA-36 New Brave 400.

11.Piper PA-38 Tomahawk Two-seat light aircraft and basic trainer:-
Ans.
The Piper PA-38-112 Tomahawk is a two-seat, fixed tricycle gear general aviation airplane, originally designed for flight training, touring and personal use.The Tomahawk was Piper's attempt at creating an affordable two-place trainer. Before designing the aircraft, Piper widely surveyed flight instructors for their input into the design. Instructors requested a more spinnable aircraft for training purposes, since other two-place trainers such as the Cessna 150 and 152 were designed to spontaneously fly out of a spin. The Tomahawk's NASA[1] GA(W)-1 Whitcomb airfoil addresses this requirement by making specific pilot input necessary in recovering from spins, thus allowing pilots to develop proficiency in dealing with spin recovery.

Production
Tomahawk Cockpit
The Tomahawk was introduced in 1977 as a 1978 model. The aircraft was in continuous production until 1982 when production was completed, with 2,484 aircraft built.
The 1981 and 1982 models were designated as the Tomahawk II. They incorporated improved cabin heating and windshield defroster performance, an improved elevator trim system, improved engine thrust vector, 100% airframe zinc-chromate anti-corrosion treatment, better cockpit soundproofing, larger 6" wheels and tires for greater propeller ground clearance and improved performance on grass and dirt runways, among other enhancements.
