Instrument Flight Procedures Information Gateway
Wanted to put this together since it seems like this website isn't really known about in the GA pilot community and I think it's a great tool that at least every instrument rated pilot should know about.

The Instrument Flight Procedures Information Gateway (IFP Information Gateway) is a tool you can use to get answers to questions on specific procedures. The type of questions that you would use the gateway for would be those that you wouldn't typically be able to get an answer for. A good example question would be why a local RNAV approach has LPV minima that is actually higher than the LNAV/VNAV minima. It might be an error, there could be a controlling obstacle along the approach path, etc. The only way to know for sure would be to reach out to the FAA directly, which is what the IFP Information Gateway allows you to do.

Here's how to generate that query with the FAA. Follow the hyperlink above to get to the website. Once there you can type the airport identifier into the search box and hit enter:

This will bring up a page that shows all the procedures for that airport:

You'll look for the procedure in question, then hit the "email FAA" button (highlighted) for it. This will allow you to reach out to the FAA IFP team on that specific approach and get the answer you're looking for. Its been my experience that they will get back to you within a couple of days with an answer.

The IFP Information Gateway has many more features than just the one I highlighted above. You can see all the current procedures for an airport, get notifications for specific airports, see information about procedures in development, etc. They have a training video that highlights everything you can do on this website.

I hope this information is helpful to someone and you're able to get an answer to some of those procedure specific questions that you may have.

This is great!  We occasionally have these conversations at my school where a bunch of instructors sit around trying to figure out why a particular approach is the way it is.  With this we can get an authoritative answer.  Thank you for sharing!
