HAWK

Comprehensive Handling Qualities Evaluation Tool

HAWK delivers a complete toolkit for predictive handling qualities (HQ) evaluation, designed for rotorcraft, fixed-wing, and UAV platforms. It supports both flight and simulation analysis through a custom MATLAB interface, providing actionable insights for engineers and test teams.

Key Features

  • Predictive HQ Criteria & Boundary Assessments: Evaluate aircraft behavior against standard handling metrics

  • Pilot-Induced Oscillation (PIO) Analysis: Identify and mitigate control instabilities

  • Mission Task Element (MTE) Reporting: Detailed plotting and reporting for HQ tests

  • Frequency-Domain Analysis: Embedded FREDA functionality transforms time-history data into frequency responses, supports system identification, and SISO/MIMO analysis

  • Customizable MATLAB Workflows: Tailor analysis to your platform and requirements

Integration with Flight Control

Validate control algorithms and vehicle handling in simulation or flight. HAWK’s embedded FREDA analysis provides deeper insight into system performance, and it integrates seamlessly with FMU flight controllers for end-to-end evaluation.

SOAR

Optimizing Aircraft Response for HQ Analysis

As a powerful add-on to HAWK, SOAR (System for Optimizing Aircraft Response) is designed to optimize flight control gain sets to meet Level 1 HQ requirements. Using multi-stage optimization, SOAR tailors solutions to ensure optimal handling qualities for any aircraft type, including rotorcraft, fixed wing, and UAS.

Key Features

  • Optimizes control gains for Level 1 HQ requirements

  • Multi-stage optimization tailored to any aircraft type

  • Integrates with HAWK for a complete HQ evaluation workflow

  • Test optimized gains directly on FMU flight controllers for real-world validation

MCRUER

Streamlining UAM Flight Testing and Compliance

MCRUER is a tablet-based display system that transforms Handling Qualities (HQ) testing in both simulation and live flight. It can also function as a ground station for FMU flight controllers, enabling real-time monitoring, control, and data visualization during UAV operations.

With MCRUER, you can conduct virtual Mission Task Element (MTE) evaluations, reducing the need for costly physical test courses. Its data replay and visualization capabilities help teams analyze vehicle response against performance requirements, whether in simulation or live flight.

Key Features

  • Portable tablet interface for MTE display and data recording

  • Real-time flight data acquisition for accurate assessment

  • Virtual testing for both simulated and live environments

  • Adaptable for pilot-in-the-loop and unmanned system evaluations

  • Enhances visual cueing where sensory feedback is limited

  • Ground station capability for FMU, supporting integration with deployable flight controllers

MCRUER brings flight testing into the digital age—faster, smarter, and more cost-effective, bridging simulation, hardware, and live flight operations.
