Building A New Runway: How Far From Buildings?

Wed Aug 16, 2006 5:08 am

I searched the internet to find an answer to my question but I did not succeed, so maybe there are people here that can help me on this.

How large is the area around a runway that has to be free of any obstacles such as buildings or higher level terrain?
What is the minimum distance for a taxiway running parallel to the runway?

I hope there is somebody here that can help me here.

Thank you in advance!

is this an air carrier runway?? Let me start off that the answer to your questions are far from simple.

1000ft from any 'fixed' structure. Then it all depends on how tall the structure is and where in reference to the runway it is. Off the centerline? At the end?

I would suggest going to FAA.gov and research the Advisory Circulars regarding Safety Areas, Airport Design, and Imaginary Surfaces.

"Fixed" meaning what? That excludes streetlights and the like?

Personally if MAN wanted a new runway they could build it as close to my house as they wanted! The only rule I would have is that the aircraft wing doesn't scrape my car on the way past!

Quoting GodBless (Thread starter):

Well, it very much depends! Obviously, the closer to the runway, the lower the maximum height of obstacles. You may get an idea from the following map:

http://www.minvenw.nl/luchtvaartbele...es/Bijl4_blad15_4_tcm163-91148.pdf

This shows the maximum height (in meters) relative to "reference altitude" which more or less equals runway altitude (4 meters below sea level).

As it is in Dutch only, let me translate the keywords:

Horizontaal vlak - horizontal plane
Hellend vlak - inclined plane
Helling - slope

This .pdf is the most interesting one (as it shows the area next to the runways), but if you want to see all of them, as well as the ones dealing with noise and noise abatement, see the list:

http://www.minvenw.nl/luchtvaartbele...dossierschiphol/kaartbijlagen.aspx

And the policy documents:

http://www.minvenw.nl/luchtvaartbele...sierschiphol/indelingsbesluit.aspx

All in Dutch, I'm afraid. But since you appear to be Swedish, you may be able to get the overall idea!

The thing is, that these charts are "just" the norm, and exceptions may occur. If this happens, you better map them:

Hope this helps.

First of all thank you for your helpful replies. Found quite some useful information.

My question was very theoretical, but in my mind I thought about a midsize runway for commercial flights up to 100tonnes.

Did that, very useful!

The advisory circular you're looking for is 150/5300-13 (or something similar) Airport Design It defines all the "Imaginary" runway surfaces,the clear areas, etc.

There you'll find the distances required it depends on the group/category of aircraft that is intended to use the runway, e.g the required setback distances are different if you intend to use the runway for an A380 or if the primary intended aircraft is a single engine piston.

I think also Structure has to be an X "Slant Distance" away from the Runway.[Hence Height of structure Permitted can Increase with Distance Away].
Not sure of the Exact Numbers.Will need to find out.

It depends on the design aircraft (design group), the type of approach (precision/non-precision), the minimums, the field elevation, and the desired taxiway system. The Building Restriction Line (BRL) is no longer used as a design standard per se.

Example 1: The field elevation is Sea Level - easiest reference point. Your design group is Group IV (767), you want dual parallel taxiways (Group IV), you need a vehicle service road (50') and a ramp deep enough for the aircraft (250').

Your runway width is 150'. Your first taxiway is a standard 400' from the runway (centerline to centerline), or in lieu 600' for accute angled high speed exists. Your second parallel taxiway is 215' from the first taxiway (total is now between 615' and 815' from the runway centerline to the second taxiway centerline), You then have the distance from the taxiway centerline to a fixed or moveable object, this distance is 129.5' (new total 744.5' to 944.5'). Your vehicle service road and ramp depth total 300'. Thus in this scenario, your terminal wall is between 1044.5' and 1244.5' from the runway centerline. The height will vary, I'll get to that.

Example 2: The field elevation is Sea Level - easiest reference point. Your design group is Group III (737), you want a single parallel taxiway (Group III), you need a vehicle service road (50') and a ramp deep enough for the aircraft (200').

The runway width is 150'. Your taxiway is a standard 400' from the runway (centerline to centerline), or in lieu 500' for accute angled high speed exists. You then have the distance from the taxiway centerline to a fixed or moveable object, this distance is 93' in this case due to the narrower wingspan (new total 493' to 593'). Your vehicle service road and ramp depth total 250'. Thus in this scenario, your terminal wall is between 743' and 843' from the runway.

Height is more complicated. The calculation is new. It's based on the wing span, field elevation, and desired landing minimums and complicated. I'll let you read it for an ex"plane"ation:
