IF labeling on approach charts

[kevmor]

I noticed that on some approaches there are fixes labeled IF
(Intermediate Fix), such as FONTS INT in http://204.108.4.16/d-tpp/0702/00664IL14.PDF
where there is a cross radial, but other approaches such as EJAAY in
http://204.108.4.16/d-tpp/0702/05850I15.PDF isn't labeled as an IF. I
looked it up in the AIM but it didn't really give me a reason why some
have it and some don't?

It was a policy change about 2 years ago. It is added to a procedure
when it is revised.

So they're adding the IF labeling to new/revised approaches? What does
that labeling do for you anyway?

Nothing, except for RNAV IAPs, where ATC (as of a year ago) can clear
you direct to the IF provided certain conditions are met. If there are
any stepdown fixes before or after the IF, it is impossible to tell
which fix (waypoint) is the IF unless it is charted.

Sam, my understanding was that atc must give you ** vectors ** to the
final approach course, or you start the app at the ** IAF **. With
atc now possibly clearing you direct an IF, am I now behind the times?

As to RNVA IAPs you are behind the times. ;-)
