Traffic pattern direction

Hi,

the IFD540 seems to provide everything that I need but there is one thing that I can't seem to find. Is there any place where it will provide information on whether a specific runway is left or right hand traffic?

I'm thinking if you go to the info tab and bring up the destination airport, the pattern information might be there but I cant be 100 percent sure until I go look.

It's not there. I had previously submitted a request to include the pattern direction overlaid on the runway depiction on the info tab.

ForeFlight provides pattern direction (e,g, left traffic) in the Traffic Pattern box in the runway tab for the airport.

Correct, we don't show traffic pattern direction on the IFD because that data is not in the Jepp data we get.

I bet that the Jep Pricing model adds another $1000 a year for that data.

*ducking*

The sim starts with KMLB as the default starting point, can you use that as an example for where you found the data? I don't see it. Thanks.

Sadly, that is not in any way consistent. Check out a few other airports with right hand traffic.

Not sure what you would like it to be?

All Jeppesen can do is report what has been given to them by whatever authority is operating the airport via the FAA or directly.

Where does airnav.com/AOPA/iFly/Adventure Pilot/fltplan.com/.../.../... and everybody else get information that Jepp cannot?

As an example for my home airport, KIYK, the FAA has published runway patterns, but Jepp does not supply it, at least not that I can find in the 540. It's actually important at KIYK because they changed the pattern for 20 (a long time ago) because a left pattern will likely put you into the restricted area immediately east of the airport.

Pilot Geek,

I did check the Google Earth picture of Inyokern and see that your segmented circle around the Wind Sock is properly marked and in good shape. Very nice!

Good Afternoon Pilot Geek,

A very good question indeed!

I checked the AirNav listng for KIYK (Inyokern) and find no mention of any specified traffic pattern direction. Neither the government charts or the Jeppesen charts list the right turn for Rwy 20.

However, ForeFlight DOES list right traffic for Rwy 20, but not on the approach plate. Where do YOU suppose they got that information?

What have I missed?

Happy Skies,

Go HERE (http://www.faa.gov/airports/airport_safety/airportdata_5010/), which is an FAA.gov website.

For the example of IYK, go to the City pulldown and select Inyokern, then hit submit. This will bring you to a page to access information about the airport. Under Data Downloads, Select Airport Runways Data, this will provide you with a .xls download. You should also look at the data dictionary for how understand the previous .xls data.

In the spreadsheet, you'll find that 02/20 has BaseEndRightTrafficPattern set to N (Left traffic for 02) and ReciprocalEndRightTrafficPattern set to Y (Right traffic for 20), all of the rest of the fields are N for left traffic for 15, 33, 10, and 28.

You may think this was a lot of work for 1 airport, but you could have left all of the fields in the request form to 'ALL' and been able to pull all of the information at once, the file is under 6MB.

Here is the snippet from airnav showing that runway 20 is right traffic.

RUNWAY 2		RUNWAY 20
Latitude:	35-38.896000N		35-39.783667N
Longitude:	117-50.002167W		117-49.352000W
Elevation:	2441.6 ft.		2413.7 ft.
Gradient:	0.4%		0.4%
Traffic pattern:	left		right

From the FAA the traffic pattern information (altitude, where present, and direction -- always) is available in the book formerly known as the AFD -- now the Chart Supplement.

It is my recollection that the data is available from Jeppesen, but it may not be in the data that Avidyne gets from Jeppesen, depending upon what they have requested/negotiated.
