What is the minimum weather requirement at an alternate airfield when the destination has a ceiling of 2900 feet and visibility of 2 miles?

The minimum weather requirement at an alternate airfield is influenced by the approach and landing minimums of the destination airport. In this scenario, the destination airport has a ceiling of 2900 feet and visibility of 2 miles. According to regulations, when filing for an alternate, the minimum weather requirements generally mandate that the alternate must have weather conditions that are either at least equal to specific minimums or adhere to the established standards for alternate airports.

For alternate airports, the typical minimum is 'non-minimums' plus 300 feet and 1 statute mile visibility, which translates to a requirement that the alternate airfield must have at least a 300-foot ceiling and 1 statute mile visibility. This ensures that in case the primary destination experiences worsening conditions, the pilot has sufficient weather conditions to safely reach the alternate airport.

The reference to 'non-minimums' indicates that if the destination's weather is above the normal minimums, you can then apply the additional standard (300 feet and 1 mile). This makes option B the most suitable answer, as it incorporates this requirement adequately, providing a safety buffer for alternate flight planning.
