Airfield - dispersal / runway line dimensions

[chocksaway]

This is probably a dumb question ...

Is there a standard for width / length of modern RAF / RN airfield runway / dispersal lines?

I'm looking to do a few diorama bases - runway and dispersal - and would like to get the dimensions for the following

1 - runway centre-lines
2 - runway "piano keys"
3 - runway numbers
4 - yellow dispersal parking lines
5 - dispersal "squares" (i.e. if tarmac is divided into squares)
6 - taxy lines

I don't mind if I get scale or real life versions - as long as I know the scale.

Thanks for any info

Hi Chocks

Have you tried looking at some of the airfields on Google Earth. It's now possible to look at so many military and civil airfields on there at the punch of a button and you can zoom in real close to see a lot of detail.

If you see a truck, a car or even the occasional aircraft anywhere, you can use that as a basic guide to compare the size of the features you want to replicate.

Put up RAF Lossiemouth UK and you will fly direct to the base in seconds. Type in your next destination and Google will take you right there too in seconds.

Hope that helps.

Tarmac is not used on an aircraft operating surfaces as it can't support the weight and it melts in the jet blast. All surfaces are concrete. Taxi & marshalling markings depend on the aircraft being operated at the airfield. A general rule of thumb is that the main yellow line is for the nosewheel(s) to follow and the markings either side of that are a guide for the main wheels. As a marshaller you aim to get the aircraft sitting on these lines so that the ASP doesn't get dangerous - wingtip collisions are best avoided.

As Nige says, using Google Earth is great for overhead detailed views.

There is also a Measuring Tool on the task bar. By selecting this (and setting it whether you want the info in Metres or Feet) you can then measure the distance between any two points.

By using this method you can get the complete dimensions of the whole airfield/airport.

Many thanks for the info - some light reading ahead! I'll try Google Earth - my worry (but not tested) would be the lack of resolution to get a suitable level of accuracy). It'll be no worse probably than that of my models and may well be better.

Cheers and thanks again
