2023 Grob 120 Tp

Main Features At A Glance

Thoroughbred basic trainer aircraft optimized for the demanding military training environment.

Full aerobatic & military training capability (+6 / -4 g).

Excellent handling qualities and simple single lever ‘turbine-like’ power plant operation.

Proven dependability and supportability of the Rolls-Royce M250-B17F turbine engine.

Power availability appropriate to the phase of training:

Power can be physically limited to 312 SHP for ab initio training phase (Flex Power).

456 SHP for take-off and 380 SHP for maximum cruise provides excellent power-to-weight ratios and with instantaneous excess power during normal operations.

5-blade, constant speed MT-Propeller.

Only aircraft in its class certified to latest FAR 23 crashworthiness requirements.

Most spacious side-by-side seating in its class.

Student pilot can be seated either in the LH or RH pilot seat, both with individual throttle levers.

Robust retractable landing gear optimized for rough training environment.

Furnished with latest state-of-the-art avionics (analogue/digital) allowing seamless transition to modern training platforms.

Primary flight display (PFD) in digital flight deck variant features tapes display or round dial display being unique for this class of trainer aircraft.

VFR day / night and IFR operations in non-icing conditions.

Available safety features include traffic advisory system (TAS), digital flight data and cockpit voice recorder

(FDR & CVR) and mission debriefing system (MDS).

All composite airframe: lightweight, corrosion and fatigue free, easy repair.

Unbeatable low total life-cycle cost to its fibre reinforced composite airframe, requiring less maintenance effort.

High service life of the airframe of minimum 15,000 flight hours (aerobatic).
