A pilot is planning a VFR cross-country flight from Aerodrome A to Aerodrome C via an en-route turning point B. On the aeronautical chart, Leg 1 (A to B) measures 22 NM, Leg 2 (B to C) measures 18 NM, and the direct straight-line distance from A to C measures 34 NM. What is the total route distance for this flight?
Answer
40 NM
Explanation
The route consists of the two chart-measured legs via Gleichenberg; the keyed total is **40 NM**. The answer is a cumulative route distance, not a straight-line distance between endpoints. **Key takeaway:** Add each leg when a route includes a waypoint. **Glossary:** Leg: one segment between successive route points.
