Runway Safety Buffer Zones

I need a little help from all of you out there. Does anyone of you happen to know the regulations regarding the size of runway safety buffer zones as approved by the FAA? How many feet off the end of the runway must this zone be and how far off the centerline of the runway does it have to exist? Are there any restrictions regarding buildings within or in close proximity to this buffer zone ? I couldn't find the info in the "history" of this item.

Thanks
Ed

From: http://aerosafety.zodiac.com/?p=aircraft

"The FAA requires a 1,000-foot long Runway Safety Area (RSA) at the end of each Part 139 airport runway. Many airports cannot comply with this safety area length requirement due to naturally occurring obstacles, such as rivers, highways, railroads and populated areas."

Also, check out the Advisory Circular from the FAA:

In addition, the only things that are allowed in Runway Safety Areas are navaids that are fixed-by-function (ie localizer antennas, approach lights). By a certain year, all 139 airports that don't have 1,000' of safety area must have EMAS installed... great news for ESCO, the patent holder on EMAS

500 feet wide on centerline.

read that AC - you'll get to know a new word - "frangible"

Interesting discussion topic... Is a person "frangible"? 3 inches... how tall are ankles?

a person IS considered frangible - you have no idea how many times I've walked right over the edge of the runway during a landing/take-off. Short of the 747 scene in Pushing Tin, it is awesome!

What exactly is EMAS?

Or displace the threshold to give 1000' from runway end (runway end not necessarily pavement end"

As long as you have permission to be there by ATCT.

I think you mean relocate the threshold. Displacing the threshold leaves runway in place and available for use and does not alter the RSA.

As to the initial question with regard to RSA's, RPZ's and OFZ's - they vary (start on page 35):

Partially correct. It depends on the design group. See page 40 in the link Boeing7E7 provided.



Just when I think you've said the stupidest thing ever, you keep talkin'!

No problem. This is a new version of the file and has end-around taxiway standards as well.

It may well be the same for the FAA, but smaller commercial airports require a safety box of just 90m at the end of the runway according to the CAA, that's 45 meters either side of the centerline. My local had to have major alterations to move a road as the previous safety area was only about 15 meters, finally being completed and opened literally minutes before the regulations came into force.

Yeah, I did something close to that with an Air China Cargo 747 landing... It was definately on of those... "I'm getting paid for this?" Moments.
