In a flight plan, the purpose of the alternate aerodrome is to provide what?

• A. Primary arrival airport
• B. Backup landing site
• C. Preferred climb gradient
• D. Primary en route waypoint

Answer: (B)

The idea behind an alternate aerodrome is to have a backup landing option if landing at the destination becomes unusable. When you plan a flight, you assess whether the destination will meet your landing minima. If it won’t—due to weather, runway closure, or other issues—you need a place you can divert to and land safely, within your fuel and time constraints. That place is the alternate aerodrome. It isn’t about the primary arrival point, climb performance, or a navigation waypoint; it’s specifically a prepared landing option you can use if conditions at the destination deteriorate.
