Nice catch on 168441, I monitor these daily, had two up today, 168441/168854 & 168384/(169327), the latter still doing doughnuts just s/w of KNIP. Not been able to fully pin 384 down as 327 yet but my ££££ is on it.

1503- Dinah 28 working PAX Approach (120.05). Asks if runway is classified as "wet" or "dry".
Dry Runway. A runway is dry when it is neither wet, nor contaminated. For purposes of condition reporting and airplane performance, a runway can be considered dry when no more than 25 percent of the runway surface area (within the reported length and the width being used) is covered by visible moisture or dampness, frost, slush, snow (any type), or ice.
Wet Runway. A runway is wet when it is neither dry, nor contaminated. For purposes of condition reporting and airplane performance, a runway can be considered wet when more than 25 percent of the runway surface area (within the reported length and the width being used) is covered by any visible dampness or water that is ⅛ inch (3 mm) or less in depth. Note: A damp runway that meets this definition is considered wet, regardless of whether or not the surface appears reflective.
Luckily BISON 21 missed their tail number the first time so WIZARD had to repeat it because I missed it the first time too!Nice catch on 168441
They need to know the runway condition to calculate the landing performance, perhaps to make sure that they are legal to land on runway 14 instead of runway 24 with the gusty crosswind. The required landing performance is different in the civilian world for dispatch and actual landing, different depending on the regulations e.g. Part 91, 135 or 121 and differs according to when the aircraft was originally certified. And, any maintenance issue that can affect stopping distance like a brake or thrust reverser deactivated is sometimes a player as well. I'm not sure how the Navy does it with the E-6s, Terry Pavlick probably knows something about this subject.
For the sea lawyers, here are the wet and dry runway definitions from FAA Advisory Circular 25-31:

Pilot sounded quite calm.
It's interesting that they only ask for wet or dry and the FAA only seemed to address that, in the past they would have a "RCR" Runway condition reading, where base ops hauls off down the runway with a bike wheel apparatus off of the back of a truck or car, and measures coefficients of friction. which if there were a little oil on the runway (or more rubber than normal, or anything else) would seem like a more useful thing to know.
Perfect... I knew there had to be more to it than just wet or dry. Thank you.In an attempt to provide the desired granularity to the runway braking action reports, the FAA has come up with this Runway Condition Assessment Matrix.

Loudoun Co rescue is currently responding to Dulles for a reported crash on Rwy 19R.
PAT07 is the area is reporting a small single engine plane down and it's intact. Apparently off the airport somewhere.
Rescue now being sent to 21583 Megawatt Dr. Cessna-size plane lost power while on approach. Occupants out and fine.
Must be this one.
GTX502 Rescue confirms it as N732YA. Pilot says there's still 20 gallons of fuel onboard.
