• A. Course Leg
• B. Spiral Course
• C. Grid Leg
• D. Sweep Leg

Answer: (A)

In aerial reconnaissance for mapping a radiological hazard, data are gathered along defined straight-line flight segments between navigation points. Each of those straight-line segments is called a course leg. The pilot flies directly from one checkpoint to the next, using that segment to collect measurements and define the extent of the hazard along that line. This approach ensures consistent sampling and clear documentation of the area covered. Other patterns describe different flight shapes: a spiral course involves circling or turning inwards or outwards, a grid leg is part of a grid pattern with perpendicular lines to cover a square area, and a sweep leg refers to broader sweeping motions. The description of flying a straight line between two checkpoints aligns with the concept of a course leg.
