Grob 115E

Hello All

Looking for a little help with information please.

Is there anyone on here that can give me two or three significant differences between the Grob 115E and the Grob 115EA.

Many thanks.

Grob don't list the G 115EA as a certificated variant, nor are the RAF/Babcock's aircraft registered as such, so I assume it's just a marketing designation.

The Grob G 115 is a general aviationfixed-wing aircraft, primarily used for flight training. It is built in Germany by Grob Aircraft(Grob Aerospace before January 2009). The E variant with a 3-blade variable pitchpropeller is in service with the Finnish Air Force,[1] the Royal Navy and Army Air Corps for Flying Grading (a pre-EFT flying course) and in the Royal Air Force as part of No. 6 Flying Training School (6 FTS) which provides flying to both University Air Squadrons and Air Experience Flights to Cadets of the Royal Air Force Air Cadets.[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 Prefect T1.
In 2009 some Tutor squadrons began to receive new Enhanced Avionics (EA) Tutors, with an updated and enhanced instrument panel, featuring a Garmin GNS 430W GPSsystem, digital HSI and digital engine instruments.[[i]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.

Looking at the pictures it appears to gain an aerial on the spine but loses one underneath.

A bit like the RAF's shiny new Falcon 900LX fleet, then - a variant that doesn't officially exist but was invented by the marketeers to describe a 900EX with some avionics upgrades.

The Tutor fleet began mods in 2008, just after I retired from Farnborough, and were modded by GAMA Engineering at Farnborough, arriving in 2s and 3s.
At the same time, the AAC Lynx fleet were being modded at Fairoaks (avionics upgrade again) by Mann Engineering, which became GAMA shortly afterwards but they've all been replaced by Wildcats so I wonder how many were sold off or just scrapped.

The Tutor EAs have been around for about 10 years now. This was a press release at the time:

Lees Avionics has been awarded a contract by Babcock to upgrade 93 Royal Air Force (RAF) Grob 115E training aircraft, also known as the Tutor Fleet.The upgrade includes installation of Avidyne TAS600 traffic advisory systems and a Sandel Electronic HSI, for improved situational awareness and collision avoidance.

The upgrade programme to improve the safety of the aircraft was launched after two mid-air collisions in 2009.

Before the EA (Enhanced Avionics) upgrade, they were designated G115E, so shouldn't they be referred to as G115EEA now ?

Similar designation changes were on the Beech Baron B58P which was pressurised, the then Lamp maintenance schedules covered up to 2730 KG MAUW meaning anything over that needed a dedicated maintenance programme that cost more to use.
The B58P weighed in about 2812 KG MAUW which was 80 odd KG over the limit, so Beech introduced the B58PA that simply wrote the Max All Up Weight down about 100 KG to bring it in limits for the U.K. same aircraft, same weight, just a reduced load capacity as a paper exercise and an A on the designation to make it legal.
