I was flying out of JFK on Monday, Jan 15 in the evening. Departures were on 22R. Since it was in the midst of the evening bank of departures, we had a good 45 minute wait. However the taxi procedure was different from what I've experienced at JFK (I was on UA Express).

We taxiid (sp?) out onto 13L with some aircraft while other aircraft went onto taxiway C. We got in line and sat in one position for a good 20 minutes while aircraft on C advanced forward, seemingly even ones that joined the line after us.

Then, we finally advanced and our entire group of aircraft took off. As we advanced toward 22R, we passed the other aircraft that joined after us (they were simply holding further ahead on C).

Anyhow, I've never noticed a long hold like that while a group advances. is this usual for departures on 22R? I've usually left on 31L. Perhaps it conserves fuel?

thanks!

Depends. Last Monday there were some heavy sector delays in and out of ZNY. Usually flights to sectors closest to the one you are leaving on will be the one to experience an additional ground delay in order to keep the rest of the flow (majority of traffic on time) This is otherwise known as spacing or miles in trail. I assume if you were on a UA RJ that you were probaby headed to IAD..? If so, you were headed to the very next sector and can only file a flight plan at 180 feet.

All in all, it seems as though they put the flights to the farther sectors ahead and then let you go, then created the taxi and wait on taxiway charlie.

Or...if all that is incorrect, you had a ground controller in a bad mood..lol.

This is normal for 22 operations at JFK - They don't want to have lines that are too long, so they break it into two - one goes on taxiway C, the other on 13L, and they alternate which one is moving. If they didn't do this, the line on C would stretch all the way around and create tie-ups on A and B, which are the two main taxiways that planes use to get to their gate.

13L is also the holding pen for flights that have to wait on the ground when takeoffs are on 22R.

In an interesting turn of events, JFK operated with departures from 31R and arrivals in 31L yesterday for a period of time.

It has been years since I've seen a 31R departure (save the recent DL Freedom Air props).

Anyone know why this happened yesterday? Furthermore, anyone have any idea how rare this actually is?

I think it is a shame that 13L/31R is so underutilized...

This I believe is due more to the routing out of JFK then anything else.

I've done plenty of 31L departures, but never 31R.

yes, I was headed to IAD and there were delays all over the place due to the weather.

Last time I can recall that happening was when 31L was closed due to a Turkish A340 sliding off the runway in the aftermath of the blizzard last winter. The winds were too strong to use the 4/22s, so they sent everybody to 31R.

It's not underutilized at all. JFK normally operates in the "one runway for arrivals, one for departures" mode. When the 31s or 13s are in use, 13L/31R is the main landing runway, and it gets a lot of use during the peak arrival periods. Because of the way the airspace is set up, it would be impractical to depart off of 31L and 31R simultaneously, since both runways have to make a left turn after takeoff to stay away from LGA. However, when there is a big enough gap in arrivals, it is possible to depart from 13L and 13R simultaneously.

Exactly. Also, the controller tells the pilots in the stationary line to shut down their engines and warns them before the last few departures of the moving line to start them up again, all in order to save fuel.
