Grob G 109

The Grob G 109 is a light aircraft developed by Grob Aircraft AG. It is a two-seat self-launching motor glider in which the pilot and passenger or student sit side by side, with good visibility provided by large windows. The G 109 prototype and the G 109A production form first flew in 1980, the G 109B followed in 1984. The G 109 was the first motor glider built using composite construction to be granted Federal Aviation Administration approval.
As well as normal civilian use this aircraft is now also used in Volunteer Gliding Squadrons (VGS) by the Royal Air Force to train Air Cadets through the Gliding Induction and Gliding Scholarship courses. The G 109B is known in RAF service as the Vigilant T1.

Grob G 115

The Grob G 115 is a general aviation fixed-wing aircraft, primarily used for flight training. The E variant with a 3-blade variable pitch propeller is in Royal Navy, Army Air Corps and Royal Air Force service as an elementary flying trainer. The 727 Naval Air Squadron (squadron of the Royal Navy Fleet Air Arm) currently operates five Grob Tutor trainer aircraft under a private finance initiative with Babcock International's aerospace division.
The aircraft is constructed of carbon composite materials. The main fuselage and each wing spar is a single piece. It has a fixed (sprung steel) tricycle undercarriage with spatted wheels, a short nose bearing the 180 hp engine and a 3-bladed variable-pitch propeller. The aircraft was re-certified in 2013 with a new MT Propeller following issues with the previous design. The inverted oil system was also redesigned to improve lubrication during aerobatics. The cockpit features a broad canopy arch and spine. Forward visibility is good. The side-by-side seats are fixed and pilot seating is adjusted with cushions as well as a rudder bar adjuster. The wings are tapered with square tips and the empennage consists of a large fin and rudder with an oblong tailplane with square tips mid-set to the fuselage. The initial Grob G 115 and G 115A models had an upright fin and rudder and were mainly sold to civilian aeroplane clubs in Germany, the United Kingdom and several other countries. The aircraft is capable of basic aerobatic manoeuvres (limited to +6G and −3G).
