Scenario 22: How does 'terrain avoidance' capability in an RPAS system contribute to safety?

Question: Scenario 22: How does 'terrain avoidance' capability in an RPAS system contribute to safety?

Answer options:

• It allows the RPAS to manually adjust its altitude based on pilot input.
• It prevents the RPAS from flying into designated no-fly zones. ✅ It automatically adjusts the RPAS's altitude to prevent collisions with obstacles or terrain, especially when flying autonomously or BVLOS.
• It provides a visual representation of the terrain on the ground station display.

Correct answer: It automatically adjusts the RPAS's altitude to prevent collisions with obstacles or terrain, especially when flying autonomously or BVLOS.

Explanation: Terrain avoidance systems use sensors (e.g., LiDAR, radar) to detect and avoid ground obstacles and changing terrain elevations, crucial for safe autonomous and BVLOS operations, preventing controlled flight into terrain (CFIT). The correct answer is "It automatically adjusts the RPAS's altitude to prevent collisions with obstacles or terrain, especially when flying autonomously or BVLOS.".
