The stock clearance into HPN from the POU area is IGN V157 HAARP. It's
been that for as long as I've been flying around here. Recently, they've
started issuing IGN V157 VALRE V157 HAARP, which boils down to exactly the
same thing (VALRE is just a bend in V157).

Today, I asked the controller about it. His response is that he just
reads
what gets printed on the strip, and they've been wondering the same thing
in the Tracon :-).

Does anybody have any idea why the ATC computer would be generating
clearances with the same airway mentioned twice?


Don't know if anyone's still looking at this post, but I have another
theory -- you used DUAT or DUATS to file the flight plan. Both of those
systems (I am a lead programmer for DTC's DUAT system) have a requirement to
make sure the route of flight is validated by the ARTCC host computer
system. There was a situation where the ARTCC computers were rejecting the
DUAT flight plans (about 12 years ago) because the ARTCC computers don't
have all of the U.S. fixes in their databases. The solution for the DUAT
systems was to insert a fix along an airway when the airway leaves the first
center's airspace and enters another center's airspace.

Once the DUAT system sent the flight plan into the FAA's systems, the
controller just reads off the route as they get it.
