How should a pilot assess the need for an alternate airport in preflight planning?

• A. Based on pilot's personal preference.
• B. Based on weather at destination and alternates, minimum fuel, and regulatory requirements for alternates.
• C. Based on available seating.
• D. Based on aircraft color.

Answer: (D)

In preflight planning, the need for an alternate airport is about ensuring there’s a safe place to land if the destination becomes unusable. You evaluate the forecast weather for the destination during your expected arrival window, focusing on ceilings, visibility, and any indications that conditions could deteriorate. Then you check potential alternates to see if they have acceptable weather and viable approaches that you can actually fly to with your aircraft. Crucially, you also confirm you have enough fuel to reach an alternate and still meet reserves as required by regulations. If the destination is forecast to be below landing minimums or the route to any suitable alternate is not feasible within fuel and regulatory constraints, you must designate an alternate. Choices that rely on something irrelevant to flight planning, like aircraft color, don’t apply to this decision.
