The Grob G 120TP is a two-seat turboprop training and aerobatic low-wing aircraft with a composite airframe, built by Grob Aircraft. It is based on the Grob G 120A training aircraft and has been developed for military and civil pilots training. It has a retractable tricycle landing gear and a low tailplane.

The first customer was the Indonesian Air Force. EASA Part 23 type certification was completed in May 2013.[1]

Design and development

[edit]

Designed to be a further development of the G 120A, the G 120TP turned during the development process into a nearly new type of aircraft. Due to the new powertrain, the G 120TP offers new capabilities for basic and advanced pilot training, where it can be used as a lead-in for a jet trainer.[2]

The airframe is made of fiberglass reinforced plastic and is stressed to +6/-4g. The wings are made of carbon fibre composites with winglets.

The cockpit provides room for students and teachers wearing military equipment and helmets. The HOTAS control system is similar to that found in other types of aircraft that students may fly later in their careers. Therefore, basic and advanced flight training for future transport aircraft, helicopter, or jet pilots will be possible. The cockpit is equipped with movable seats, or optionally, the new Martin-Baker Mk.17 lightweight ejection seats. The instrument panel can be equipped with a 4-screen Genesys Aerosystems IDU-680 EFIS.[3][4] An autopilot and air conditioning system are available, as well as an oxygen system and second thrust lever.
