I’m studying for the FAA Instrument Written exam. It’s driving me crazy. While reading this question, I was thoroughly amused by the ridiculous number of acronyms in this one question and its possible answers.

How does a pilot determine if DME is available on an ILS/LOC?

A– IAP indicate DME/TACAN channel in LOC frequency box.
B– LOC/DME are indicated on en route low altitude frequency box.
C– LOC/DME frequencies available in the AIM.
