Remarks (Bemerkungen)
In developing the G 140TP, Grob Aerospace seeks to define a new class of aircraft. The four-seat turboprop is intended as a lower-cost alternative to the single-engine turboprops being used at present. It is both a high-performance trainer and a fast comfortable means of transportation. Equipped with thermal-image cameras, the all-plastic aircraft can also be used for example for patrolling or surveillance. Potential customers being targeted are military and civilian flight schools as well as pilots who would like to have a fast airplane for their business trips but would also like to experience the thrill of aerobatics. It is built entirely of glassfibre, with the sturcture offering a service life of 15000 hours. EFIS-avionics and air-conditioning are standard equipment.

History (Geschichte)
Development of the G 140TP had started in secret in early 2001. The prototype of the Grob G 140TP (D-ETPG) was a surprise exhibit at the Paris Air Show in June 2001. At that time, certification was expected in late 2002.
Flight tests of the G 140TP started on on December 12, 2002. According to Grob, the first flights displayed even better performance potential than original calculations had indicated: As well as higher airspeed - more than 220 knots have already been achieved - the aircraft also attained a rate of climb of 2,700 feet per minute.
