[2] As of 2020, the Tutor is still being used by the RAF for some Elementary Flying Training (3FTS) but is due to be phased out in favour of its replacement, the more advanced Prefect T1.

It has a fixed (sprung steel) tricycle undercarriage with spatted wheels, a short nose housing the 180 horsepower (130 kilowatts) piston engine, and a 3-bladed variable-pitch propeller.

The aircraft was re-certified in 2013 with a new MT Propeller following issues[weasel words] with the previous design.

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.

There are only six recorded Herons in existence; two (to be sold) operated by Tayside Aviation, three privately owned, and one in Germany.

Royal Navy, British Army, and Royal Air Force Elementary Flying Training (EFT), where students streamed according to ability: Fast Jet, Rotary Wing, Multi-Engine or non-pilot roles, was previously taught on the Grob Tutor at RAF Cranwell and RAF Barkston Heath by the joint 3 Flying Training School, with 703 Naval Air Squadron, 674 Squadron Army Air Corps, and 57 RAF Reserve Squadron, before being replaced in 2018 by the more advanced turboprop trainer, the Grob G120TP Prefect.

[citation needed] These aircraft are the same as the standard Tutors, with the exception of an extra VHF aerial for the new GPS system and the cockpit modifications.
