Sos! Rnp=wtf??! ...---...

This is from the July 31, 2005 AFS-410 document revising the Aircraft Equipment Suffix Table. LINK /W aircraft are still expected to have limited RNAV capability, just not the Advanced RNAV to comply with Type A or B Terminal RNAV procedures.

c. Aircraft with RNAV Capability. For flight in RVSM airspace, aircraft with RNAV and RVSM capability, but not Advanced RNAV capability, will file “/W”. Filing “/W” will not preclude such aircraft from filing and flying direct routes in enroute airspace.

Here's a link to an FAA document to determine if your installed equipment is capable of complying with Type A or B RNAV procedures per AC 90-100. AC90_100 Compliance Table.

Interesting. The subparagraph you've quoted seems to contradict a line from the first subparagraph of the same document and the table at the end.

1. Introduction. An effective time of “0901 UTC” is added for this update.

a. Effective September 1, 2005 at 0901 UTC, when filing an FAA Flight Plan (FAA Form 7233-1), operators will use a new set of aircraft equipment suffixes to indicate Advanced RNAV and RVSM capabilities. Either “/J”, “/K” “/L” or a newly defined “/Q” will be filed to indicate Advanced RNAV and RVSM capabilities. “/W” will continue to indicate RVSM capability only.

The last line of the Suffixes / Equipment Capabilities table shows /W is simply "RVSM." There is no mention of RNAV capability, Advanced or otherwise.


Maybe that's why the controllers are still confused.
