What is the 800 2 rule for IFR?

If a usable precision approach is available: 600' ceilings AND 2 SM of visibility. If only a non-precision approach is useable: 800' AND 2 SM of visibility. If no instrument approaches are available: Descent from the MEA and landing must be conducted under basic VFR.



The "800-2" rule refers to the standard weather minimums required for a pilot to list an airport as an alternate in an IFR (Instrument Flight Rules) flight plan. Under FAA regulations (14 CFR 91.169), if a pilot is flying to a destination where the weather is forecast to be below certain limits, they must designate an alternate airport. If that alternate airport has a non-precision approach, the weather at the time of arrival must be forecast to have at least an 800-foot ceiling and 2 miles of visibility. This is contrasted with the "600-2" rule for airports with a precision approach (like an ILS), which requires a 600-foot ceiling and 2 miles of visibility. In 2026, these are the "standard" minimums; however, many airports have specific "Non-Standard Alternate Minimums" published on their approach plates, indicated by a "t" inside a black triangle. Pilots must always check the specific charts, as some airports may have higher requirements due to terrain or lack of weather reporting, while others may be completely prohibited from being used as an alternate during certain conditions.

They won the '1,500 hour' rule, flight time required before a pilot could be hired as a first officer at a commercial airline. This was adopted even though both Colgan Air pilots had.. more than 1,500 hours. The rule wasn't meant to prevent future Colgan Air disasters. It was meant to make it harder to become a pilot.
