But surely none of the flyers participating would ever fly above the approved height clearance would they? Hmmm

I wonder how many pilots seeing the group of three flashing lights on the ground would actually recognise their significance?

I'm just wondering how this works when you have multiple kites that are closer than 25m to each other, do you have a really big equilateral triangle or multiple overlapping triangles? Also is the green light upwind or downwind of the anchor? My assumption is that the two red lights are upwind and the green light is downwind and below the flying line thus marking the anchor and forming an arrow pointing in the direction that kite is flying.

It all sounds very complicated to me so I will leave it to you you will find me in the bar

This is how I read it, might be totally wrong View downwards for a pilot

That would make sense - but you are right it could be either way. The pilot would hopefully have some idea of the wind direction to navigate correctly but that doesn't allow for the wind being in different directions at different levels.

My assumption is that the two red lights are upwind and the green light is downwind and below the flying line thus marking the anchor and forming an arrow pointing in the direction that kite is flying. This is how I read it, might be totally wrong View downwards for a pilot I think you are twisted by 60 degrees. The first step is to project the kite line horizontally onto the ground, i.e. draw a line on the ground directly below the kiteline The second step is to draw a line at 90 degrees to the first line and to one side of the anchor (it does not say which side) The third step is to mark two points on the second line, one either side of the anchor and at least 25m apart. A red flashing light is then placed on each of the points. The fourth step is to take two pieces of string the same length as the distance between the red lights and anchor one at each red light. The fifth step is to hold the two un-anchored (you will need to pass one around the flying line) ends of the strings and walk out until the strings are taught and the anchor is encompassed by the strings and the line between the red lights. Place the green flashing light at this point. The green light always indicates the direction of the kite in relation to the baseline marked by the red lights but because of the lack of the instruction as to whether the base line is upwind or downwind of the anchor you can't tell which side of the base line it will be. Though the white light on the kite will help.

Guy, he's 90o out not 60o. His baseline is parallel to the string not perpendicular.

Given that it says a minimum of 25 metres and no maximum Dave could position 3 lights on the outskirts of Bognor (several kilometres apart) and everyone would be covered no matter where in Bognor they flew! Or if the wind is from the South, a red light in Portsmouth, another in Dungeness and a green light in Twickenham and that's the whole of Sussex covered!
I think they haven't thought this through properly.

In addition to the ground placement issues, there is also the question of the placement on the line, is the separation of the white light and the kite and the separation of the red and white lights is this vertically or down the length of the line? Or should the red light be suspended on a separate 4m so that it hangs vertically below the white light?

Given that these requirements apply if you are flying over 60m, and you need a NOTAM to do so, and Dave's NOTAM covers an area of 1NM radius centred on the park the the farthest apart you can place them is on the boundary of the circle. Though Dave might need some floating lights or some drone mounted ones to cover the one or two that need to be in the English Channel.

We are just flying kites, or am I missing some thing here

And then the wind shifts 90 degrees and you're all B****red anyway But have a great time in Bognor. Sorry I can't join you this year, but I am temporarily (mobile) homeless.

We just get back from Bognor what a terific weekend not a lot of wind apart from laughing and chatting. Next year we plan to add an extra couple of days to the front and end of the week end that if the hotel will play ball. A big thanks to Sheila and Dave for all the hours of hard work they put in, and of course not forgetting cuddles, that big dog who just wanted to help me get down my tent. Its a bit of a struggle wrestling a tent and 8 stone of dog. Great week end thank you both very much. Trying to book up for next year.
