PS. It comes from ICAO...

Exactly, they can do it. But just because it's legal doesn't make it a good idea - I can pick my nose whilst driving in fog at 70 mph on a wet road, legal it is, stupid as well!

Not if you're a clever dick.

Those rules on road heights apply to open roads upon which traffic is travelling.

If traffic is using the road then the reference height is surface+4.5m, but if the traffic is stopped (as it is at Waddo by the flashing red lights either side) then you can use the road surface as your reference height.

This is why Waddo has to stop the traffic for a/c movements, otherwise the road traffic would infringe the approach/climbout surfaces.

interesting question 814 , the railway comparison is a different thing as the railways and their access are covered under their own very old system. Be interested to know if with an airfield approach its just a warning for info or is it enforceable as some kind of trespass ?

Waddo undershoot
 

Having once been lowered into the grass in Waddington's undershoot by an A1 QFI I can report that it is quite a gentle, pleasurable experience. It is, however, one that I am in no hurry to repeat.

GZ, was this in an aircraft, or during a hand in hand stroll after some wine?

The boys and girls from Lincs Police were posted either side of the fence at the end of the runway today, and stopped anyone from going into that area with ladders or anything.

They did not stop them from sitting on the lights over the road however....

Still as there probably won't be another airshow at Waddo again, we will not have to worry (if that's whats happening after the refurb) in 2016????

814, if you did two tours as a snowdrop shouldn't you know what the law is?

If this was an organised, advertised 'Airshow', I am simply amazed that the people running it would allow spectators anywhere near any overshoot areas at all. That guy cops some shear and cleans some of those people up, surely there would be a valid argument that the legal duty of care lays with the organisers? Why take that risk??

Whilst LJ is correct with all the 'angle of dangle' stuff, the pragmatic answer is to displace the threshold at Waddington. I'm not sure it still needs 9000ft of Tarmac for landing (sorry, don't have E3, Sentinel, RJ manuals to hand to confirm whether a reduction of LDA by 500ft or so would significantly hinder performance).

Courtney, it's actually 50 ft threshold crossing height, which would mean a touchdown point roughly 1000 ft into the RW. Whereas crossing the threshold at 50 m on a 3° approach would mean a touchdown some 3130 ft down the RW....

If the requirement really is to have a clear area to account for an aim point 60m short of the RW threshold, then that would imply a minimum height of only 14.8 ft over the near side of the A15 on a 3° approach....which equals 4.52m.

Anyway, enough of the trigonometry. Because however you look at it, standing underneath the RW approach that close to the A15 is utterly stupid - and most certainly 'Darwinian'!

Google Earth shows the threshold some 4' below the road as well

The organisers have no power of authority for persons outside the wire. Unless there is a by-law or land owner complaining of trespass, the police have no power either. Common sense and the law are not always in sync.

What is known in the spotter fraternity as a 'naughty field' often places the public in areas forbidden by CAA and MAA regulations yet removal of offenders is not legally viable.

Yeovilton have been proactive in introducing temporary by laws closing bridleways and footpaths, but frankly all this will do is put the stn in good light in a Coroners Court inquiry. The first such court could see the end of air shows in the UK.

..... and had that F16 undershot and taken out even one spectator, the prophesy of doom would be this mornings headlines.

Different angle on this one
 

Looks like the pilot landed on or very close to the numbers (37 sec in)

Fair point Tashengurt, in my defence back in the 80’s I spent just about all my tour on the SSA site and anything relating to traffic law that I learnt back then I have long forgotten! In those days anyone stopping anywhere along the A15 was regarded with suspicion, including aircraft spotters, and generally from inside the fence we were instructed just to tell them to move on. Of course it was all double yellow lines along the road and the parking area at the WAVE didn't exist.
The reference to a train crossing was because I assumed that the principles, if not the actual law, may be the same. Looking at the Highway Code does not seem to provide the answers and this link simply references vehicles.

I think it may be that a pedestrian going past the red flashing lights at a railway crossing commits a trespassing offence under the Railway by laws but it’s not clear if the same applies to a road. We clearly need an up to date proper policeman’s view here not some retired snowdrop!

Chap in the orange t shirt on the ladder gets a bit of a fright.

I suppose the solution would be to re-route the A15 in the same manner that the A38 was moved at Bristol.

They also did that a few miles further up the A15 at Scampton, but that was quite a long time back I think, anyone know a date?
