The airport did report back in the March 2023 Consultive committee that there would be the following happening
There would be a new radar going in
A new ILS system ( presumably for runway 08 )
New fire engines and other equipment
The last meeting was at the end of July so I guess more information will come to light when it’s published anytime soon
Obviously TUI hadn’t confirmed about the 2nd based aircraft then so there could be more of a plan coming to fruition regarding the terminal as well
