What it is: the Runway Condition Assessment Matrix (RCAM) is the FAA’s method for assessing and reporting airport surface conditions. Short answer for equipment managers: the condition reported to pilots depends on what is on the pavement after your crews work, so clearing quality and equipment readiness matter. I summarise two FAA documents; I do not give detailed matrix values.
What the documents say
| Point | Source statement |
|---|---|
| Guidance document | AC 150/5200-30D, Airport Field Condition Assessments and Winter Operations Safety, helps airport operators develop a snow and ice control plan, assess and report conditions using the RCAM, and establish snow removal and control procedures. FAA lists it as Active, issued 2020-10-29 in a consolidated version with Changes 1 and 2. |
| Start of RCAM reporting | CertAlert 18-02 says the NOTAM system incorporated the TALPA RCAM method on October 1, 2016 |
| Where it applies | The CertAlert says to use the RCAM to report conditions on paved runways only; its condition description section can apply to all airport surfaces |
| Who uses the code | Pilots use the reported Runway Condition Code and reported contaminants to determine landing distance requirements near the time of landing |
| Stop rule | If a runway has a code of 0 on one or more thirds, operators must stop operations on that runway and perform mitigating actions |
| Reassessment | After mitigation the operator reassesses; the code may change or no longer be reported if contamination is 25% or less of the overall runway length and width or cleared width |
What this means for equipment
Clearing quality depends on machines that start and run.
- Mitigation depends on machines. A runway in a stop condition needs equipment that works when called.
- Clearing quality shows up in the reassessment. The reassessment looks at what contamination remains.
- Edge condition is part of clearing quality. A worn or damaged edge leaves more on the surface; how much depends on the surface and conditions, and I have no measured figures.
- Documentation helps. Keep equipment readiness records beside your snow and ice control plan.
What to do
The summary is not the regulation; read the current AC.
- Read the current AC and your approved plan, not this summary.
- Make the equipment checklist part of the plan review.
- Keep edge height checks in the pre-shift routine.
Query date: October 24, 2026. FAA documents can be revised; confirm the current version.
Boundary: I read the FAA document page and CertAlert 18-02 only, not the full AC. This summary is not regulatory advice; follow the current FAA documents and your approved plan.
