Grob Aircraft-H3 G120TP

Hey IFC hope your all doing well, I’ve decided to create this feature thread for the 120, as I really feel it would be great addition to the IFGA community & IFAE GAF both as pilot trainer and recreational aircraft. I believe it bridges the gap between the C172 & TBM, offering a very capable modern type

Grob Aircraft

Located Tussenhausen a municipality in the district of Bavaria, Germany. Since its foundation in 1971, Grob Aircraft have produced a wide range of aircraft. Initially manufacturing recreational / competition gliders, it swiftly started developing products for other aviation markets.

The company has gone to produce a wide range of Genaral Aviation / Trainer aircraft many of which have been operated in quantity by a number of military air wings. It is also know to have produced specialised high-altitude intelligence surveillance and reconnaissance (ISR) aircraft.

G120TP / Prefect T1

Built in 2010 is a two seat tandem - low wing, turboprop training aircraft. Like it’s predecessor the aircraft is possess aerobatic qualities, with a fibreglass / carbon fibre airframe. It developed from the G120A training aircraft and is specifically designed for military and civil pilot training. It has a tricycle landing gear and a low tailplane / winglets. Additionally it features a large cockpit like 120A and is equipped with 2x new Martin-Baker Mk.17 lightweight ejection seats. The instrument panel can be equipped with a 4-screen Genesys Aerosystems IDU-680 EFIS (Glass Cockpit). An autopilot and air conditioning system are available as well as an oxygen system and second thrust lever too.

Designed as a development of the G120A, the G120TP is a highly modified variant of the 120A. This is partially due to the new powertrain it is equipped with. The G120TP offers new capabilities for basic and advanced pilot training where it can also be used as a lead in platform for a jet training aircraft.

The aircraft is also equipped with a unique HOTAS (hands on throttle-and-stick) control system, similar to that found in other types of aircraft that students may fly later in their careers. Therefore aiding, basic and advanced flight training for future transport aircraft, helicopter or jet pilots.

How great would it be to fly this in formation?

Makes a change from commercial routes ;)


Great Idea! Would be good for GAF and just to increase the variety of General Aviation airframes!
