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

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 optional the new Martin-Baker Mk.17 lightweight ejection seats can be chosen. 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.

 Argentina
Argentina is the second operator of the G 120TP. Deliveries of the first batch of four aircraft started in June 2013. 10 (+5) aircraft were ordered.[5]
 Indonesia
The launch customer for the G 120TP was the Indonesian Air Force with a total delivery of 24 aircraft (the contract is for 18 aircraft +6 follow-up orders out of 14 optional) as well as a G 120TP – Flight Training Device.[6][7]
 Jordan
The Royal Jordanian Air Force (RJAF) has awarded Grob Aircraft in order to supply 10 aircraft, a CBT System and one G 120TP FTD for elementary pilot training. Delivery of the first batch of two aircraft is expected to be in April 2016.[citation needed]
 Mexico
The Mexican Air Force (FAM) has selected the Grob G 120TP as its new elementary trainer. The contract contains 25 aircraft (+15) equipped with the Genesys Aerosytems EFIS IDU-680. The delivery of the first batch was in February 2015 and final batch in February 2016.[8][9] The training will be completed by a Computer Based Training (CBT) System and four G 120TP Flight Training Devices.[10]
 Myanmar
The Myanmar Air Force operates a fleet of 20 G 120TP (+10) training aircraft equipped with Genesys Aerosystems EFIS IDU-680. The pilot training will be supported by a CBT System and one G 120TP FTD.[citation needed]
 United Kingdom
The future UK Military Flying Training System (MFTS) program will provide British military pilots elementary training on G 120TPs according to some press reports. The system replaces separate flying fixed-wing and rotary training programs for the Royal Air Force, Royal Navy and Army Air Corps. The service provider Affinity will likely include the G 120TP together with the Beechcraft T-6 the initial, basic and advanced training, and with the Embraer Phenom 100 the Transport Pilot segment.[11]
 United States
The United States Army selected the G 120TP to provide comprehensive initial and recurrent training for more than 600 U.S. Army and U.S. Air Force fixed-wing pilots annually, covering transition of army rotary-wing aviators and training of army initial-entry fixed-wing students.
Together with CAE USA, Grob Aircraft will provide turnkey training services including academic, simulator, and live flying training with a total of 6 aircraft at a new training center to be built at Dothan Regional Airport in Alabama, close to the U.S. Army's Aviation Center of Excellence (USAACE) at Fort Rucker.[12]
