/R means that the aircraft is capable of operating in Required Navagational Performance (RNP) airspace and routes. In other words, it has RNAV capability.

In addition, the aircraft has a Mode C transponder.

/R = aircraft is equiped with functional transponder, altitude reporting and RNAV (Area) navigation equipment. RNP is just one of many methods of meeting the RNAV equipment requirement. There is also GPS, FMS, VORTAC computers, etc.

Thanks for the reference Night_Flight. I queried AA management and FOT replied. I'm told the FAA made the "recent change" to AIM and AA had it "scheduled" for the September manual revision, but it "somehow didn't make it." I'm also told AA's computer was already displaying the change with notes on all flight plans except 737s (only RNP aircraft in AA's fleet = remained /R before & after the change). Finally, I'm told this change is "scheduled for the next revision."  Yeah sure Knowing management personnel, one can imagine the fast paperwork that might have been going on earlier today. Thanks again.  Big thumbs up
