The minimum volume required to be scanned by a helicopter in order to provide a known amount of warning time before potential collisions with static terrain is identified. These volumes are useful because they enable stealthy use of active sensing for safe terrain avoidance. The paper identifies an efficient method for calculating the volumes and provides illustrative results of their shapes. Furthermore, the approach is adapted to account for non-instantaneous scanning, providing a practical sensing strategy. Again, simulations illustrate that a specified warning time is ensured.
