For a VFR flight away from the departure airport, which distance calculations must the PIC determine?

• A. Runway lengths and takeoff/landing distance for airports of intended use
• B. Maximum endurance range
• C. Distance to the nearest weather beacon
• D. Local navigation grid pattern

Answer: (A)

The key idea is performance planning for a VFR flight. Before you depart, you must know that the airports you’ll use have enough runway for your aircraft’s takeoff and landing performance under the expected conditions. That means calculating the runway length available at departure and at any destination or alternative airports, and comparing it to the aircraft’s required takeoff distance and landing distance (including any needed accelerate-stop distance and contingencies) given weight, density altitude, wind, surface, and slope. If the available runway is not sufficient, you adjust weight or choose a different airport.

Other items aren’t part of this distance-planning requirement: maximum endurance range isn’t about takeoff/landing feasibility, distance to the nearest weather beacon isn’t a performance-distance calculation for departure, and local navigation grid pattern isn’t a determining factor for whether you can safely operate from the planned runways.
