[therock]

What are the exact requirements for a runway to be called wet?

Should know this by now but I watch to much Television.

I dunno, but when I was in a tower, and we had to discontinue LAHSO with wet runways, I called 'em wet any time I could see either wet-looking pavement or rain falling.

 

[Say Again Over]

I think if it's not raining it would be something like; visible standing water or shiny appearance.

What are the exact requirements for a runway to be called wet?

One carrier I worked for used this criteria:
Grooved runway and no "standing water" (i.e. big puddles - I guess) - consider the runway dry. Standing water or worse = wet. So a grooved runway with a good "pitch" for proper drainage off the surface could be pretty wet and still be called "dry".
Non-grooved runway and any kind of "sheen" from moisture - wet.

I don't know if that is FAR driven, aircraft type specific, or up to the company to develope criteria for their own operations. I just remember the above was in the company FOM.

LAND AND HOLD SHORT OPERATIONS DEFINITIONS, GENERAL OPERATIONAL REQUIREMENTS, AND TRAINING REQUIREMENTS.​

A. Definitions.

1. Land and Hold Short Operations (LAHSO). Land and Hold Short Operations is the practice of conducting simultaneous operations on two intersecting runways, either two aircraft landing simultaneously, or one aircraft landing while another is taking off. Land and Hold Short Operations includes landing operations to hold short of an intersecting runway, taxiway, predetermined point, or an approach/departure flight path.

2. Available Landing Distance (ALD). Available landing distance is that portion of a runway available for landing and rollout for an aircraft cleared to Land and Hold Short. This distance is measured from the landing threshold to the hold-short point.

NOTE: Air Traffic Control (ATC) personnel are responsible for providing the ALD for each LAHSO runway through the Airport Terminal Information Service (ATIS) and from the appropriate control tower when requested. The ALD data is published in the U.S. Terminal Procedures publications and in the special notices section of the Airport/Facility Directory (A/FD).

3. Dry Runway. A dry runway has no visible moisture on the runway surface, to include standing water, ice, snow, slush, or frost in any form. Land and Hold Short Operations is not authorized on wet runway surfaces.

Thanks to all for their input. I've done some research in my squadron and talked to a number of pilots from different airlines. It sounds like each company/aircraft can have their own exact definition but the consensus was:
Wet- runway with shiny or mirror appearance but no standing water

Contaminated-straight from the AIM
CONTAMINATED RUNWAY- A runway is considered contaminated whenever standing water, ice, snow, slush, frost in any form, heavy rubber, or other substances are present.

I think your should take another look at that.

 

[Say Again Over]

That is our criteria too.

 

[CaptainSpaz]

That is also the criteria we operate under. FoxHunter, do you have something to add?
