I have explained the reasons , maybe this will help.

How do FDDs and display pilots ensure they deliver a safe flying display?

The FDD must first identify the area within which they plan to locate spectators (spectator area) and ensure it is suitably displaced from the area within which display pilots will fly (display area).

Display pilots will use an easily identifiable display line which the FDD is required to mark and is set at a minimum separation distance from the forward edge of the spectator area (more commonly referred to as the crowd line).

The minimum separation distance between the crowd line and the display line is normally 230 metres, but this can be extended to 450 metres for aircraft that conduct manoeuvres at speeds in excess of 300 knots, or reduced to 150 metres for helicopters and light aircraft (see Figure 1).


Figure 1 – Display Area Layout

Display pilots are permitted to fly down to minimum heights within the display area as specified on their display authorisation or public display authority.

The minimum heights vary depending on the type of aircraft involved, the display pilot's approval and hazards within the display area itself.

The FDD is required to brief display pilots on the flying related risks and hazards associated with each specific event and is responsible for the safe coordination and necessary adjustments to the flying display programme on the day.

Display pilots are responsible for the choreography of their display routine, which must ensure the aircraft retains adequate energy throughout a manoeuvre to maintain safe separation from the spectator area.

I'm guessing the curve on West Bay makes the display line harder to adhere to under newer regulations as the aircrft would turn around the beach area to head North so it wasn't a straight display line.

As I recall the display line for West Bay was based on a straight line between two points, Black Rocks and Ramore Head, and then moving out 200m. Since the majority of spectators in West Bay were along the beach and promenade this put them even further back from the display and meant that any fast jets were merely dots in the sky.

That's the same weekend as the Belfast tattoo so I wonder if we will be graced with a typhoon or two over Titanic again. I went down in the rain with the kids and for the 5 second glimpse and roar it was well worth it. But I doubt I'll be attending Portrush as its my youngest ones birthday. Would liked to have travelled to Ayr but hey ho.
