What is a VFR ceiling?

VFR means a ceiling greater than 3,000 feet AGL and visibility greater than five miles. Marginal VFR (MVFR) is a sub- category of VFR. This exercise helps establish your personal “comfort level” for VFR, MVFR, IFR, and LIFR weather conditions.

How do you find a cloud ceiling?

Find the difference between the surface temperature and the dew point. This value is known as the “spread”. Divide the spread by 4.4 (if temperatures are in °F) or 2.5 (if temperatures are in °C), then multiply by 1000. This will give the altitude of the cloud base in feet above ground level.
