CVA (Ceiling and Visibility Analysis) is a real-time analysis of current C&V (ceiling and visibility) conditions across the continental U.S. The product is primarily intended to help the general aviation pilot (particularly the VFR -only pilot) avoid IFR conditions. However, CVA's quick-glance overview of ceiling and visibility conditions can be useful to others involved in flight planning or weather briefing. To remain current in rapidly changing conditions, CVA is updated every five minutes. The overview provided by CVA should be followed by further examination of METARs, TAFs, AIRMETs, Area Forecasts and other weather information.
Disclaimer and Warning
By FAA policy, CVA is a Supplementary Weather Product for enhanced situational awareness only. CVA must only be used with primary products such as METARs, TAFs and AIRMETs.
