The Grob 115E is known by the RAF as the Tutor.
It is used for Elementary Flying Training by all 3 of the Armed Services. Additionally, 14 University Air Squadrons and 12 Air Experience Flights throughout the UK provide Air Experience Flying and Flying Instruction to university students and members of the Air Cadet Organisation.
The Tutor can cruise at 130kt at sea level and climb to 5,000ft in 7 minutes. This performance, along with a modern instrument and avionics suite, including a Traffic Avoidance System, makes the Tutor an ideal aircraft for Elementary Flying Training.

The Tutor is constructed mainly from carbon fibre reinforced plastic, which combines high strength with light weight. Like its predecessor, the Bulldog, the Tutor has side-by-side seating but, unlike the Bulldog, the primary flight instruments are on the right-hand side of the cockpit. This allows the student to fly the aircraft from the right-hand seat with a right-hand stick and a left-hand throttle so that future transition to fast-jet aircraft is made easier.
Unpressurised, and powered by a Textron-Lycoming 180hp piston engine driving a Hoffman three-bladed, constant-speed propeller, the Tutor can cruise at 130kts at sea level and climb to 5,000ft in seven minutes. The aircraft has a very clean airframe and has a three-minute inverted-flight time limit, making it ideal for aerobatics where, unlike previous RAF light aircraft, it loses little or no height during a full aerobatic sequence. The aircraft has a very modern instrument and avionics suite, including a Differential Global Positioning System, which, apart from giving excellent navigational information, can also be used to generate a simulated Instrument Landing System (ILS) approach for training use at airfields where ILS ground equipment is not fitted for the runway in use.
The Tutor is a cost-effective, modern elementary training aircraft. The combination of docile handling characteristics and good performance make it very suitable for its training role.
