Many airspace design concepts for integration of traditional crewed aircraft and new entrants such as drones and advanced air mobility aircraft are based on geo-fencing, i.e. constraining the aircraft flight within a certain operation volume or corridor. Such volumes are designed based on the predicted flight trajectory and a buffer which accounts for flight errors. Once the volumes are determined, the pilots need to control the aircraft within them. This research focuses on the lateral component and proposes a multi-layer volume deviation alert part of a situation awareness tool and based on the current flight position and tests the concept in a flight test using Japan Aerospace Exploration Agency’s experimental helicopter. Prior to the flight test, it was assumed that alerts at 100 m, 200 m and 300 m thresholds will enhance the flight safety without impacting the mission performance, but the results showed that the 100 m alert increases the pilot workload without contributing significantly to the volume conformance. It was demon-strated that the pilot was able to correct the course of the aircraft as soon as the alert was issued, verifying the effec-tiveness of the approach. Pilot feedback was also used to obtain directions for improved volume and alert design. The research confirmed that the multi-layer volume concept can be applied to enhance flight safety without increasing pilot workload, provided the operation volume and alerts are properly designed.
