For preflight planning at an alternate, you must add to the published minimums for precision approaches which value?

• A. 200-1/2
• B. 150-1/2
• C. 300-1
• D. 250-1/2

Answer: (A)

When planning an alternate, you must apply a safety margin to the published minimums for the approach you’d use. For precision approaches, the standard planning margin is 200 feet in altitude plus 1/2 mile in visibility. This means you treat the alternate minimums as higher than the published ones by those amounts to account for weather variability and other factors, ensuring the alternate would be usable if conditions are not as good as the primary destination. So the correct addition is 200 feet and 1/2 mile, matching the option with 200-1/2. The other options don’t reflect this standard planning margin.
