Number of a runway ???

superbou · 02-28-2010, 06:10 PM

Hi all,
I was just wondering how the name of the runway are given.
What I know is the final letter L or R is for Left or Right but from where
are coming the numbers 08L, 21R ... ???
Thanks for your answers guys.

It is named after the Heading the runway is facing. For example if a Runway is facing a heading of 240 Degrees, it would be Runway 24L/24r.

"Heading" is only part of the story.

The designation is in degrees MAGNETIC. Not TRUE.

So now that you know what 08L, 21R mean, what would the other end of 08L and 21R be, Arnaud?

mkeperson · 02-28-2010, 09:13 PM

The approach end of the runway's heading in magnetic degrees (rounded to the nearest 10..drop the zero) determines the number. That is, if you are flying due east (compass heading 90 degrees) to land on the runway, it will be labeled as Rwy 9. If you land on the same runway flying west, the same Rwy is labeled Rwy 27 (reflecting a compass heading of 270 degrees). If there are parallel runways, they would be 9L/27R and 9R/27L. Three runways would be 9L/27R, 9C/27C, and 9R/27L. If you have four parallel runways the convention changes. Lets say the runway magnetic heading is 93 degrees. One pair will be named 9L/27R and 9R/27L. The second pair will be labeled 10L/28R and the other 10R/28L. Even though all four runways really have the same directions.

Clear as mud!!

Pendulum19 · 02-28-2010, 09:48 PM

It's basically compass directions. I think this question can be better addressed with illustrations.

dylan · 03-01-2010, 12:11 AM

Holy hell! Can maybe 5 or 6 more folks chime in with the EXACT SAME ANSWER?

steve kicic · 03-01-2010, 12:29 AM

Its all about compass headings!! There you go, and if ya want to get really tech, the numbers have to be painted to certain sizes and styles to Aviation Industry Authourity standards!!

AirTran Airways 717 · 03-01-2010, 12:40 AM

I know the answer to this question, but like dylan said; holy hell 5-6 people already answered it so there is no use in me saying the exact same answer.

Absolutely! In your honor: It's basically compass directions. I think this question can be better addressed with illustrations.

You are all wrong...they put 36 numbers in a hat...and they get the least important person at the airport...have him pick it and whala... you have a runway number. Get it straight peoples...

that's also how they choose the pilot

hitanykeytocontinue · 03-01-2010, 03:25 PM

Hilarious!
Haven't laughed as much as now for the whole day. Thanks guys...

Btw, I think it's quite an interesting topic, 'cos I've actually never even thought about where the numbers could be from. Of course I had to have a look on my home airport (thx to Google Maps) et voilá: 08L/26R and 08R/26L. There really are 180° in between

Now Arnaud, didn't have the chance to answer

. And glad you got the spelling of voilá right

dylan · 03-02-2010, 01:52 PM

Remember, the runway # doesn't always corrspond to the magnetic heading. Sometimes, the numbers are changed to avoid confusion. Example: Atlanta KATL has 5 parallel runways. Facing east, they all have a 092 degree heading, yet are numbered 8LR, 9LR, 10.....same goes with the other side obviously. You can see why this was done.

I'm pretty sure if they were all parallel they would be 9LL, 9L, 9C, 9R, and 9RR.

I did not know that. YYZ for example has 3 parallel runways. Facing west: 05 06L and 06R. I always thought the heading was slightly different!

Hey, it could work....or something like 9FL...Far Left.

Again, here is a perfect example. Facing east, they're all 067 degrees....so they're actually closer to "07". In a couple of years you might see them changed to 6 and 7LR (and the recip of course)

Shutting down the bar as Dylan approaches......

The approach end of the runway's heading in magnetic degrees (rounded to the nearest 10..drop the zero) determines the number. That is, if you are flying due east (compass heading 90 degrees) to land on the runway, it will be labeled as Rwy 9.

One pair will be named 9L/27R and 9R/27L. The second pair will be labeled 10L/28R and the other 10R/28L. Even though all four runways really have the same directions.

Clear as mud!!

I thought we all agreed that we had put this matter to rest. This keeps up we can talk about why runways sometimes get renamed ;0)

Not quite as clear as mud: MIA,PHX,YYZ all have 3 parallel runways and none are designated a "Center". The "Center" designation seems to only come into play when they are all within close proximity of eachother: IWA, old DTW, etc...

fly Frontier · 03-03-2010, 12:11 AM

Phx is 7L, 7R, and 8.

No, no....you are incorrect. They are 25L, 25R, and 26.

No your both wrong. They are:

8-26

7L-25R

7R-25L

Tupi, you're an amateur so it's forgiveable.

7L-25R

26-8

25L

And the other one.
