Here’s a question asked by
an AOPA member who contacted our aviation services staff through the
Question: On a recent
IFR flight I experienced loss of RAIM capability on the GPS. I promptly
notified ATC, and they requested a new equipment code. My aircraft has DME and
a Mode C transponder, but I couldn’t remember the code! Where can I find that
information?
Answer: In your case,
the equipment code would have been slant alpha (/A). Refer to table
5-1-2 in the Aeronautical Information
Manual for other aircraft equipment suffixes.
