Summary
This study investigated how audiovisual cues affect remote pilot performance in Remotely Piloted Aircraft Systems (RPAS). Findings show that enhanced sensory feedback can improve flying accuracy and timeliness, supporting multimodal cueing for future RPAS operations.
Area of Science:
- Aviation Human Factors
- Human-Computer Interaction
- Aerospace Engineering
Background:
- Remotely Piloted Aircraft Systems (RPAS) are expanding civil aviation, but pilot feedback differs from manned aircraft.
- Current RPAS operations rely on visual cues, either direct (VLOS) or camera-based (BVLOS), lacking auditory feedback.
Purpose of the Study:
- To evaluate the impact of audiovisual cueing on remote pilot manual flying performance.
- To determine how different visual displays and auditory feedback influence RPAS operation accuracy and timeliness.
Main Methods:
- Eighteen pilots performed navigation and spotting tasks under various conditions.
- Tested were three visual display types (VLOS, BVLOS-Monitor, BVLOS-Goggles), with/without auditory feedback, and in calm/wind conditions.
Main Results:
- Horizontal deviation and timeliness improved in the BVLOS-Monitor condition for navigation tasks.
- Auditory feedback showed mixed results, improving performance in some instances and degrading it in others.
- Task specificity and audiovisual feedback levels significantly influenced pilot performance.
Conclusions:
- The effectiveness of audiovisual cueing is task-dependent and varies with feedback levels.
- Multimodal dynamic sensory cueing should be considered for future RPAS to optimize remote pilot performance.

Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
