How Do Airports Name Runways

I was just thinking..hoe does an airport decide what to label a runways (15, 24...)

thanks

RE: How Do Airports Name Runways

It is based on their direction in degrees.

I.E., Rwy. 15 is 150 degrees North-West. From the other direction, it would be Rwy. 33, at 330 degrees South-East.

If there are parallel runways, then the L or R designation is tacked on to indicate left or right.

RE: How Do Airports Name Runways

11 = 110 degrees
18 = 180 degrees

If there are parallel runways, then you would see:
25L
25R

If there are more than two parallels, then one (set) will be off by a degree.

RE: How Do Airports Name Runways

Runways are named by their magnetic heading, and the last digit is dropped. For instance Runway 25 is on a magnetic heading of 250. That is also why the same runway, approached from the opposite direction will be 180' different. So at DAB here its runway 25 if approaching from the east, and the same runway is runway 7 if approaching from the west. 70 (Rnwy 7) +180 = 250(Rnwy 25).

If there is parallel runways, such as here at DAB, then you have 25L and 25R, or 25 left and 25 right, and its reciprical 7L and 7R.

If there is more than 2 parallel runways, then you get, for example, Runway 9L, 9C, 9R or 9 left, center and right.

Where some people get confused is a situation like Orlando where you have 4 or more parallels. MCO has 4 runways with a 18/36 heading, but are labelled as 18L, 18C, 18R and 17. They all share the same heading but starting with the 4th runway they will name it 10' off for clarities purpose.

And runway names will change occassionally. Magnetic north changes slightly over time, and so every so often the runways will be renamed to the correct value as it shifts.

Hope this helps.

As HaveBlue says More than Three Parallel runways,not Two necessatite the 4th to be offset by one Degree in naming.Remember C is still an option.

If you had 5 parallel runways you could just call them 9Left, 9Center Left, 9Center, 9Ceter Right, 9Right. LOL

I can imagine ATC at an airport with that setup would be a nightmare...

It would be more like 9L, 9C, 9R, 8L and 8R.

 Quoting HAWK21M (Reply 6): offset by one Degree in naming.Remember C is still an option.

Not by one degree, but by 10 degrees. By one number maybe, as in 9 going to 8, but that represents 10 degrees, 90 to 80.

RE: How Do Airports Name Runways

One should keep in mind, however, that though a 3rd parallel runway does not necessitate a different number, it is done anyway, especially in the case of airports with two distinct sets of runways that have the same heading. Examples:

LAX: 7L/25R, 7R/25L, 6L/25R, 6R/25L
DTW: 3L/21R, 3R/21L, 4L/22R, 4R/22L
PHX: 7L/25R, 7R/25L, 8/26
ATL: 8L/26R, 8R/26L, 9L/27R, 9R/27L (though with construction of another runway, I'm assuming there will be a 9L/27R, 9C/27C, and 9R/27L)
DEN: 16L/34R, 16R/34L, 17L/35R, 17R/35L

I was just wondering about this the other day. The new 5th runway in ATL is a bit of a distance from the 8/26 pair. I don't think it would make good sense to change 8R/26L to 8C/26C, just to re-establish 8R/26L as the new runway, as I think this would cause a bit of confusion (not that it doesn't exist already today    . Wouldn't this be a good reason for using 7/25?

Why? You could put them at 86, and call those the 9L/R/C, and then at 84 and call them the 8L/R/C, right? 2 degrees of difference would be alot less problematic geographically/geometrically than 10.

The FAA allowed ATL to use 10/28 for the fifth runway. Left to right during an approach 10/28 makes the most sense. You've got 8L/R 9L/R 10 and 28 27L/R 26L/R.

RE: How Do Airports Name Runways

Remember, there are other designations for runways aswell. E/W/N/S for the cardinal directions, G for glider, etc.

Feasibly, you could have 18W/36W, 18L/36R, 18C/36C, 18R/36L, 18E/36E.

At my local airport, we have two parallels, 8G/26G and 8/26. 8G/26G is a glider runway while 8/26 is the normal powered runway.

Interesting, I never knew that. SO E/W/N/S would designate the easternmost/westernmost/northernmost/southernmost runways? Or runways whose heading is directly east/west/north/south?

Meaning, would it be 9E/27W (due east/west), or 18E/36E (easternmost runway)?

Thanks,

The runways aren't physically aligned on a different heading. Usually they will all have the same heading. It's only the runway designation which changes by one digit (10 degrees) either way. The approach plate will show the actual inbound heading to use to the nearest degree.

So does any airport use E/W or N/S instead of R/C/L?

RE: How Do Airports Name Runways

ANC had an interesting runway number choice until this June or July. Previously the two parallels were 6L/24R 6R/24L, both with a 068 degree heading. The numbering was changed to 7L/25R 7R/25L. On one of the audio archives from the liveatc archives, a pilot asked the tower how the new runways were working out..... in jest of course.

RE: How Do Airports Name Runways

LHR is one of the few recent examples where runways have had to be renumbered because of magnetic variation. They used to be angled 275/095 degrees, meaning they were numbered 28R/10L and 28L/10R. However due to magnetic variation the direction now is 274 degrees so they were renumbered.

Boeing Flown: 701,702,703;717;720;721,722;731,732,733,734,735,737,738,739;741,742,743,744,747SP;752,753;762,763;772,773.

RE: How Do Airports Name Runways

Miami's runways were renumbered when the third parallel runway was added.

27L/09R became 27/09
27R/09L became 26L/08R

The new runway was designated 26R/08L

Not sure why they chose to designate the existing runways as they did, other than to ensure the two runways closest together (the new one and the old 27R/09L) had the same heading numbers.

Well, everybody's talking about numbers, but the title says "naming" runways. To my knowledge, only AMS gives real names to its runways (Buitenveldertbaan, Kaagbaan, Aalsmeerbaan, Zwanenburgbaan, Polderbaan, Oostbaan).

Anyone knows another example?

Yes, in Zurich the runways have names, I am not sure if they are official:

16-34 is "Blindlandepiste" (blind-landing-runway) because it was the runway which had the first ILS many decades ago. 14-32 is "V-Piste" because it forms a V with the 16-34. 10-28 is simply "Westpiste" (west runway).

Or didn't you actually read the question

At least from an FAA standpoint anyway, runway naming implies the 'numbering' of runways.
