Where can I find alternate airport minimums?
The easiest way is to look at any approach plate for the airport. In the notes section of the government plates, there will be a black triangle with an A in it.

What is the 123 rule in aviation?
It’s called the 3-2-1 rule, and it’s the easiest way to remember the regulation. To recap, if the weather at your destination isn’t at least 3 SM of visibility and 2000′ AGL ceilings from 1 hour before to 1 hour after your ETA, you need to file an alternate.

- 800′ ceiling, 2 miles visibility, if non-precision approach.
- 600′ ceiling, 2 miles visibility, if precision approach.
Can a GPS approach be used as an alternate?
For airports with both ground-based navaid IAPs and GPS-based IAPs, the GPS-based IAPs typically would show as NA for filing as an alternate. The NOTAM now allows an option to flight plan for use of a GPS-based IAP at either the destination or the alternate airport, but not at both locations.
When should I file alternate airport?
You need to name an alternate airport on your IFR flight plan if, for the period of time one hour before and one hour after your estimated time of arrival, the weather is forecast to include a ceiling of 2,000 feet agl and/or visibilities less than three statute miles (the 1-2-3 rule).
