APP/DEP Frequencies

[William Sneller]

It seems that the APP/DEP frequencies are not available anywhere except the PDF of the CSUP.  In foreflight its readily available. In Avare (not x) it occasionally appears in a remarks category, but seemingly only if there are two. My research shows this has been an issues since 2016 at least. 

Is there any change APP/DEP frequencies can be added to the in app CSUP in AvareX. It looks like it should be fairly easy to extract from the PDFs as the relevant lines in the pdfs all contain "APP/DEP".

For example 6D6 is included as an attachment.

[David Farleman]

I would like to add another vote to the request for APP/DEP frequencies listed with the frequencies on the Main tab for an airport. 

Would be nice if they were there when utilizing the long press of an airport on the map or the single tap of the airport under Find.

Thanks!

Dave

I've had two flight instructors ding me during a flight review,  and review prep, for not being able to access the information printed in the margins of the paper charts.  I only brought my tablet to the review.  One issue was a TSRA in western New York.  The approach frequencies seem to only be available in the frequency table in the chart margins.   It's the only source of the TRSA frequencies that I've been able to find.   I'm not sure how foreflight show them, but they were not happy that I didnt have all available information at hand.  It would be nice if the supplemental info from the chart - frequencies, legends, special use and MOAs could be accessed somehow, even if not integrated into the map.

George, interesting comment and a good question. But I'm sure many of pilots are flying around with EFBs and not bringing paper charts, so I think the challenge is finding out what other options there are for getting such information. Usually a flight service station would probably provide all that information by radio. Or, in the case of TRSAs I believe that the primary Airport ATIS would offer the approach control frequency which most likely is the controlling frequency for the TRSA. If not  one can always go to an IFR chart, pick up the center frequency and they'll give you anything you need as well. That's the way I've done it in the past and it seems to work pretty well it just takes a little advanced planning in my view.  John

The TRSA and App frequencies are in the chart supplement page for the airport, which comes up under the "Plates" tab in AvareX. During flight reviews I always query pilots if they are familiar with the chart supplement page (and not rely on Foreflight interpreting it for me). It has a lot more than comm frequencies. Sometimes, the PCL is not the same as CTAF, and this can get you when flying to an unfamiliar unlit airport at night (ask me how I know). Chart Supplement is the authoritative source, and I am glad AvareX is able pull up the raw PDF page. 

Where the sectional margin is useful is for looking up effective times of MOA's and Restricted airspaces. This information doesn't seem to be in the Chart Supplement. But AvareX already shows this under the SUA tab. I don't know where this information is being pulled from.

Thanks Andrew.   

It was a bit challenging to find the csup pages in the plates, but I finally got there.  The hamburg menu in the lower left of the plate wasn't obvious to select the other pages including the csup pages.  Thanks for the assist.

[William Sneller]

I really think the APP/DEP frequencies should be moved to the main page. The CSUP plate is the final authority but it's hard to read and adds to the workload. If it's just a matter of harvesting the frequencies from the CSUP, I'd be glad to give the coding a try.
I suspect this is in the database file and not done in the app?

[Brett Friermood]

My understanding is that the some information, such as the APP/DEP frequencies, is only available within the CSUP raster images. I am not aware of that information being available from an official database source that would allow it to be represented accurately within the main airport information page.

At best it may be able to be extracted from the raster images by optical character recognition but that method is not always accurate, and the location and format of that information sometimes varies by airport (ie. it's not intended to be machine readable data).

[Apps4av Support]

I agree. I cannot find this info anywhere in faa data set. Only on csup and charts.

The frequencies are available in the new CSV files in the NASR data set, in the file FRQ.csv, but getting them isn't perfectly straight forward.  You have to look at the SERVICED_FACILITY, SECTORIZATION, and FREQ_USE columns to figure out which ones are APP/DEP.  Look for "CLASS " followed by B, C, D, or E in the FREQ_USE column, and a match for the facility ID in SERVICED_FACILITY.  SECTORIZATION will give the text that describes the directions or areas for which the frequency should be used.

Thanks for the motivation. Found that the info is also available in legacy data not csv. It will appear in release 100 and cycle 2605.

So cool!  Thanks for the good work.

Yup, the info is both in legacy and CSV.  If I remember right, the sectorization info in the CSV is a bit more detailed.

Thanks again!
