I am quoting this directly from the FAA's Instrument Procedures Handbook publication.
"The communication strip provided near the top of FAA approach charts gives flight crews the frequencies that they can expect to be assigned during the approach. The frequencies are listed in the logical order of use from arrival to touchdown."
Never once have I been trained to contact clearance delivery prior to CTAF during the execution of an instrument approach procedure, much less any time other than when I am trying to get my initial IFR clearance.
Why is this listed before the CTAF? Would a tower or ground frequency not be more appropriate and would it not be more appropriate to have it in logical order as the last frequency, not the second-to-last?
