context_page_description: The Grob G 115 is a general aviation fixed-wing aircraft, primarily used for flight training. It is built in Germany by Grob Aircraft. The E variant with a 3-blade variable pitch propeller is in service with the Finnish Air Force, the Royal Navy and Army Air Corps for Flying Grading and in the Royal Air Force as part of No. 6 Flying Training School which provides flying to both University Air Squadrons and Air Experience Flights to Cadets from the Air Training Corps and Combined Cadet Force.
  The Tutor was previously used as a tri-service trainer for Elementary Flying Training, before being replaced in 2018 by the Prefect T1.
context_section_description: 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).
