Its quite full at present becaise of the three extra H circles at the end. This has taken out about 6 FW parks.
A lot of people FW and RW are parking outside because of the hangerage cost. If more aircraft and rotary were put away (there is space) the congestion goes down.
As you observe, shame when it goes. Aviation has had a kick start locally (there never used to be anything flying over), now there is lots.
