Final answer:
The correct answer is option c) 800–2* or 300-1 above the lowest usable HAT/HAA and visibility, which ensures safety during flight operations in various weather conditions.
Step-by-step explanation:
For facilities with ONE USABLE PRECISION APPROACH, each providing straight-in minima to separate suitable runways, the correct Alternate weather minima requirements are option c) 800–2* or 300-1 above the lowest usable Height Above Touchdown (HAT) or Height Above Airport (HAA) and visibility, whichever is greater. This set of alternate minimums provides a safety buffer for approach and landing during less-than-ideal weather conditions. It is critical for pilots and those in aviation to adhere to these minimums to ensure safety during flight operations, especially considering that the best facilities still face weather-related limitations up to 25% of the time.
