b. 

Runway condition code (RwyCC) values range from 1 (poor) to 6 (dry). For frozen contaminants on 

runway surfaces, a runway condition code reading of 4 indicates the level when braking deceleration or 

directional control is between good and medium. 

NOTE

−

 

A RwyCC of “0” is used to delineate a braking action report of NIL and is prohibited from being reported in a FICON 

NOTAM. 

c. 

Airport management should conduct runway condition assessments on wet runways or runways covered 

with compacted snow and/or ice. 

1. 

Numerical readings may be obtained by using the Runway Condition Assessment Matrix (RCAM). The 

RCAM provides the airport operator with data to complete the report that includes the following: 

(a) 

Runway(s) in use 

(b) 

Time of the assessment 

(c) 

Runway condition codes for each zone (touchdown, mid

−

point, roll

−

out) 

(d) 

Pilot

−

reported braking action report (if available) 

(e) 

The contaminant (for example, wet snow, dry snow, slush, ice, etc.) 

2. 

Assessments for each zone (see 4

−

−

9c1(c)) will be issued in the direction of takeoff and landing on the 

runway, ranging from “1” to “6” to describe contaminated surfaces. 

NOTE

−

 

A RwyCC of “0” is used to delineate a braking action report of NIL and is prohibited from being reported in a FICON 

NOTAM. 

3. 

When any 1 or more runway condition codes are reported as less than 6, airport management must notify 

ATC for dissemination to pilots. 

4. 

Controllers will not issue runway condition codes when all 3 segments of a runway are reporting values 

of 6. 

d. 

When runway condition code reports are provided by airport management, the ATC facility providing 

approach control or local airport advisory must provide the report to all pilots. 

e. 

Pilots should use runway condition code information with other knowledge including aircraft performance 

characteristics, type, and weight, previous experience, wind conditions, and aircraft tire type (such as bias ply 

vs. radial constructed) to determine runway suitability. 

f. 

The Runway Condition Assessment Matrix identifies the descriptive terms “good,” “good to medium,” 

“medium,” “medium to poor,” “poor,” and “nil” used in braking action reports.
