Wet Runway (WR)Edit
When water is the only form of visible moisture on the runway, report the RSC as "wet runway" and no RCR.
188.8.131.52. Joint USAF/NASA tests have proven RCR measurements invalid where the only form of moisture affecting the runway is water.
184.108.40.206. The AFM or designated representative determines and reports RSC.
220.127.116.11. Specify in the AOI when other agencies are delegated the responsibility to determine and report the RSC. Regardless who determines the RSC Wet, a check of the runway is required to determine RSC Dry. Document all actions in the AF IMT 3616.
