runway questions

Hey guys,

Looking at the KLAX runways (flightaware.com/resources/airpor … IAGRAM/pdf)

I was just wondering when (if they ever) use runways 6L/R or 7L/R or what is the purpose for having the numbers that way? Listening to ATC, they always talk about taking off or landing on 24L/R or 25L/R. Just curious as to why there are numbers on the other side and if they ever use it or not.

Thanks in advance.

They are numbered that way because it would be confusing if they were numbered strictly according to their headings (249.8 degrees). You would have runways 25R and 25L but what do you do about the other two? Runway 25RC and 25LC (25 right center, 25 left center)?

LAX does use other the other runways when required.

During times when the winds are blowing the other direction, they use runways 07R/L and 06R/L. At night time due to the stupidity of politicians bowing down to the wishes of idiots buying houses next to the airport, runways 07R/L an d06R/L are used regardless of the winds. (Hey, f*ck safety - it’s better that the idiots who bought next to the airport have a good night’s sleep!)

Think about the prevailing wind at LAX…

Most of the time, the winds are out of the west. However, Standard Operations at LAX is this:

If winds are less than 10kts in any direction, use the calm wind configuration (land/depart 24L/R, 25L/R). If greater than 10kts, align best with the wind. So if winds are 140/15, they’re flipping the boat to east ops. If 160/16, that’s a direct crosswind for the 24s/25s, so they’ll stay in normal ops.

After 12 midnight, if winds are less than 10kts in any direction, they’ll go to noise abatement operations (read: suicide ops). They’ll land 6R, depart 25R. They’ll stay in this configuration until 6am local time. Then, back to normal ops. If winds exceed 10kts, this configuration is out the door, and whatever works with the winds will be used.

I have seen times when East Ops were used everywhere in SoCal; LAX was landing/departing east, ONT was landing/departing east, SAN was landing east/departing west, SNA was landing north, and LGB were using the 7s and 12. real fun stuff when you see it.

BL.

cool thanks for the reply guys. now it all really makes sense :slight_smile:

Nothing is more interesting for the controllers (and the pilots) than the first “East Traffic” in Southern California after months of using the west runways.

East traffic is rarely, rarely used from about April to September. Even during the winter months, it probably only happens about 10 percent of the time, due to cold fronts backing the winds around, or Santa Ana conditions.

So, when the first calls come out saying “LAX is east”, every airport in the area has to adjust their operations, and for about an hour every controller on position has to rethink everything.

LAX East flow during Santa Ana season is an enjoyable sight. The smog is blown out to sea, and clear skies usually prevail. In bright sunlight the pattern turns out over the water reveal some of the most gorgeous hues on a pallet of blues. The turn to final lays out the entire L.A. basin before you, and if you’re landing just before sunset the view is spectacular.
