Which are the three flight patterns used for UAS operations?

• A. Mapping, Circling, Random
• B. Linear, Spiral, Hover
• C. Mapping, Straight-line, Hover
• D. Circling, Zigzag, Gliding

Answer: (A)

The main idea is choosing flight patterns that match the task’s sensor coverage goals. For UAS operations, three common patterns are used: mapping, circling, and a more exploratory, non-structured search pattern. Mapping involves flying a systematic grid or lawnmower pattern to cover the whole area with sufficient image overlap, so you can build an accurate map or mosaic. Circling means orbiting around a point of interest to capture imagery from all directions, giving a complete 360-degree view and detailed inspection. Random (or other non-grid search patterns) is used when you don’t know exactly where targets are or when you want to maximize coverage without following a predictable path, helping to reduce gaps in unknown terrain. The other options mix patterns that aren’t typically grouped as the standard trio for UAS tasks. For example, patterns like straight-line or linear, and hovering, don’t provide the same combination of systematic coverage, full-angle observation, and flexible search coverage that Mapping, Circling, and Random collectively offer. Spiral or zigzag are less commonly cited as the canonical trio for general UAS operations.
