If destination weather meets published minimums but not 3000-3, alternate weather for non-precision must be ____________ and precision must be _______

If destination weather meets published minimums but not 3000-3, alternate weather for non-precision must be ____________ and precision must be _______

• A. Mins + 300-1, Mins + 200-1/2
• B. Mins + 100-1/2, Mins + 50-1/4
• C. Mins + 400-1, Mins + 300-1
• D. Mins + 200-1, Mins + 150-1/4

Answer: (A)

When planning an alternate, you must ensure the forecast weather at that alternate meets higher minimums than the destination’s published minimums, so you have a safe landing option under instrument conditions. The extra margin depends on the type of approach used at the alternate. For a non-precision approach, you add 300 feet to the published minimum ceiling and 1 mile to the visibility. For a precision approach, you add 200 feet to the ceiling and 1/2 mile to the visibility. This extra cushion applies even if the destination’s weather meets its published minimums but does not reach the 3000-3 threshold. So, the alternate weather must be the published minimums plus 300-1 for non-precision, and the published minimums plus 200-1/2 for precision.
