Excellent indeed
I think John R81 only made one misspelling: 2 horse_ bums.
That would leave space for VF's Star in the middle!
I do not want to upset anybody by raising the topic or the helipad again but did one think about it that
a triangular pad would actually give 6 directions to neatly park your heli?
(and a square pad only 4)

Much the same thing. I didn't mean that the width was that of 2 horses bums, but it is determined in relation to two horses bums. Roman chariots - as I understood it - were the start. Hence 2 horses with a single shaft between them. The chariots create wheel ruts, and all carts were therefore built to the same dimension because not running in the ruts would likely break your wheel. Then carriage makers were the first to create railway carriages and they simply put the wheels in the same place.
Anyway, its so nice an idea that I want to believe it is true. I think I saw it on a program years ago, which (again, I think) was called "Connections" presented by James Burke.
(you spell it your way, I'll spell it wrongly)

Thing is, it really doesn't matter too much what shape the actual helipad is, be it round, square, triangular or just an "H" marked on the surface.
Sid, did you really think I was confused by a triangular landing marking? Did you not read or understand my second paragraph (the one that begins
"Seriously though...."), or did you just deliberately choose to ignore it?
And seriously, do you really believe that any professional helicopter pilot regularly operating out of UK's busiest airport could do so without reading the relevant AIP entry before? By the way, the first photo of LHR you posted is very much out of date (Yes, I know it's a cut and paste from Google earth).

SiloeSid, no - a square pad only gives 4 different directions, as parking parallel to the left hand side of the square is co-incident with parking parallel to the right hand side of the square (assuming you park in the centre).
In general, for a n-sided polygon shaped helipad, the possible (neat i.e. parallel to a side) parking directions are:
n (if n is odd)
n/2 (if n is even)

Matthew, according to the compass in most helicopters (and provided the space is big enough), any helipad has 360 different parking directions...

Shyte, I find myself agreeing with ShyT
Matt, some of us may consider neat parking withing a square pad to include the nose/tail being aligned with the pointy bits, ie diagon alley.

Some of you guys need to get real and check out Vertical Freedom and his helipads

More to flying than a white shirt or a blue jersey and some epaulettes.

Snaks, old son, not sure what sort of perversion you're insinuating there, but only dead sheep roll away. Live sheep are stable with a lateral slope of up to 10 degrees.
Or was that the Jetranger? Mind's a bit woolly these days.
