Hi, guys, I am flying DFW-JFK-MAD-VIE later this month on Iberia.
FlightAware shows the equipment as 346/Q.
You should see this quite often now in the US, especially since
we implemented dRVSM over 3 years ago. It used to be that /W was only
RVSM capable, and that we followed NEODD/SWEVEN rules up to and
including FL290. After FL290, requirements were 2000ft vertical
separation between aircraft. FL290 would be eastbound, FL310 would be
westbound, FL330 would be east, FL350 west, up to FL600 (the top of
Class A airspace).
With RVSM, that vertical separation requirement drops to
1000ft, making every flight westbound an even flight level, while
eastbound flights were at an odd flight level, up to and including
FL410. After FL410, they go back to 2000ft vertical separation up
With that said, that didn't take care of those aircraft that
were RNAV capable. So 5 new equipment suffixes were created (/J, /K,
/L, and /Q), to indicate those that are RVSM and RNAV capable. Most
commercial aircraft are /R equipped and RVSM capable. So, /Q.
