: Confirm that the proposed technology works as intended before attempting to scale.

| Domain | System Under Test | Key Finding | |----------------|---------------------------|-------------| | Drone delivery | Obstacle avoidance + GPS spoofing | Pilot-tester detected hidden autopilot oscillation that pure HITL missed. | | ICU ventilator | Alarm management UI | Under high cognitive load, pilots missed 2 alarms; test injection changed priority logic. | | Space docking | Manual override latency | Combined thruster lag + incorrect range indication → new recovery procedure added. |

PilotTester reveals a non-linear relationship: too few injections produce overconfidence; too many produce resignation. The optimal rate follows a dynamic workload ceiling model. Practical adoption requires test pilots trained in systematic fault modeling, and test engineers trained in human factors. The framework also raises ethical questions – injecting critical faults in live systems is prohibited; hence all current applications are simulated or hardware-in-the-loop. pilottester

: Testing must occur using the actual equipment or digital environment (e.g., specific OS or browser versions) that final users will employ.

In domains where failure carries severe consequences—aviation, autonomous vehicles, medical devices, and aerospace—the gap between simulated testing and real-world deployment remains critical. This paper introduces , a dual-role framework that integrates pilot execution (human-in-the-loop, real-time decision-making) with systematic testing (automated fault injection, edge case coverage). Unlike conventional validation methods that treat human operators and test engineers as separate entities, PilotTester merges them into a single iterative loop. Results from three case studies (drone navigation, ICU ventilator UI, and spacecraft docking interface) show a 58% reduction in unhandled edge-case failures compared to traditional V&V alone. The framework offers a new benchmark for readiness levels beyond TRL (Technology Readiness Level) by adding operational resilience metrics . : Confirm that the proposed technology works as

: Ensure that end-users understand how to interact with the system or product.

The primary objective of a pilottester is to minimize risk. By simulating real-world usage in a controlled environment, developers can: | | Space docking | Manual override latency
