What is the technique called when a pilot flies a straight line between two checkpoints to define radiological hazard extent?

• A. Line Sweep
• B. Route Segment
• C. Course Leg
• D. Checkpoint Path

Answer: (C)

Mapping a radiological hazard from the air often relies on treating each straight flight between fixed points as a definable boundary segment. This specific straight-line portion, connecting two checkpoints, is called a course leg. It’s the precise term because it describes the direct, unbroken segment of the flight path between two navigational fixes, which is exactly how you delineate the extent of the hazard along a defined line. By using multiple course legs, you can piece together a boundary or footprint of the affected area. A line sweep isn’t about linking two points; it implies sweeping a line across an area to detect variation, rather than defining a boundary with straight segments between fixed points. A route segment is a more general term for part of a flight path and doesn’t inherently emphasize the straight connection between two checkpoints. A checkpoint path suggests traveling through points but again doesn’t capture the essential straight-leg concept used to define boundaries.
