What minimums are required to list an airport as an alternate under IFR with only a VOR approach?

The minimums required to list an airport as an alternate under IFR with only a VOR approach state that the ceiling must be at or above 800 feet and visibility must be at or above 2 miles at the estimated time of arrival (ETA). This requirement ensures that pilots have sufficient visual references during the approach and landing phases, as the VOR approach does not provide the same precision as an instrument approach with higher minimums.

According to the regulations, for an airport to be considered an alternate when the available instrument approach is a VOR approach, the conditions at ETA must meet or exceed these specified minimums. This regulation prioritizes safety by ensuring that if a diversion is necessary due to marginal weather, the alternate airport is sufficiently accessible.

Other choices may suggest different time frames or requirements that do not align with the established rules for listing an airport as an alternate under IFR for VOR approaches. Specifically, the emphasis on the ETA for the minimums establishes a clear reference point for pilots to assess weather conditions as they approach their destination.
