Grob G-115 Heron / Tutor

The Grob G 115 is an advanced general aviation fixed-wing aircraft, primarily used for flight training. The G 115 was first flown in November 1985.

By 1990 the G 115 had orders totalling more than 100 since production began in 1987. The two-seat, side-by-side light aircraft makes extensive use of composite materials in its construction and the resulting smooth finish gives low drag and high efficiency. The production G 115-C is powered by a single 150 hp (112 kW) Lycoming O-320-E2A piston engine driving a constant speed propeller.

The Royal Navy Flying Grading Flight operate the G.115D as the Heron.

Ninety-nine G.115E (at Tutors) were purchased for Air Cadets and University Air Squadrons in the UK. The E variant with a 3-blade variable pitch propeller is in Royal Air Force service as an elementary flying trainer.
