Special Remarks That May be Appended to the Remarks Section

Runway Condition Reporting (RSC & RCR) -- Runway condition, when reported, will include

two parts, the RSC (runway surface condition), and the RCR (runway condition reading) as

determined by the airfield manager or operations officer. The following RSCs describe the

runway condition:

Wet runway

SLR

Slush on the runway

LSR

Loose snow on the runway

PSR

Packed snow on the runway

Ice on the runway

RCRNR

Base Operations closed

The RCR is a two-digit number giving an average decelerometer reading from 02 to 25

(Figure 1-17). Two slants (//) will be entered when the runway is wet, slush-covered, or when no

decelerometer reading is available.
