Take off, Hover, and Landing (THL)
Introduction
WindShape, is at the leading edge of indoor Testing, Inspection, Validation, and Certification (TIVAC) for Unmanned and Advanced Aerial Mobility (AAM) systems. We proudly offer the integration of the Take-off – Hover – Landing (THL) assessment into our extensive TIVAC protocols. Building upon the insights capture from the WindShape Failure Mode and Effects Analysis (FMEA)—a systematic, step-by-step approach for identifying possible failures in a design, a process, or a product—the THL process is as a critical next step to validating an unmanned aircraft and/or system for safe and reliable flight. The FMEA helps enables the TIVAC process by prioritizing potential problems based on their impact, allowing for targeted improvements. The follow-on THL testing marks a significant (r)evolution in our methodology. It will enhance the operational understanding and system reliability for manufacturers, operators, and regulators. The THL offering underscores our commitment to advance aerial mobility and UAS through meticulous testing and validation, ensuring that the highest standards of safety and performance are realized before entering the National Airspace System (NAS).
The Essence of THL
The Take-off, Hover, Landing (THL) test procedure is a rigorous evaluation framework designed by WindShape. It examines Unmanned Aerial Systems (UAS) under challenging environmental conditions. This process focuses on assessing the UAS’s stability and resilience, during critical flight phases—take-off, hovering, and landing—against wind perturbations and other environmental factors. The procedure is predictively structured to ensure UAS compliance with regulatory standards, addressing both operational safety and design efficacy. By simulating real-world flight conditions, within a controlled repeatable laboratory; the THL tests provide invaluable data for refining UAS capabilities, enhancing operational reliability, and supporting continuous design improvement. This comprehensive approach not only helps manufacturers to optimize quality, but it also ensures that operators can achieve higher safety and efficiency standards, all while adhering to regulatory compliance and fostering a culture of predictive problem solving within the aerial mobility sector. The THL process, building on insights from the FMEA, offers distinct benefits across all areas of operation.

Process
The THL process, enhanced by WindShape’s innovative ‘Windshaper’ technology, represents a comprehensive approach to UAS testing across take-off, hover, and landing phases.
Take-off Phase (TOP)
The ‘TOP’ incorporates WindShape’s proprietary Fan-Array Wind Generators (called the ‘WindShaper’). This test simulates complex wind patterns and gusts, offering a realistic repeatable free-flying assessment of a UAS’s ascent capabilities. This technology allows for precise control over wind conditions, and data capture; ensuring the safety and reliability of take-offs in urban and rural environments.
A ‘TOP’ Test Example
- Wind Resistance Test – Evaluates the UAS’s capability to ascend under varying wind intensities, mimicking real urban gust conditions.
- Vertical Ascent Efficiency – Measures how efficiently a UAS can ascend, taking into account energy consumption and stability in fluctuating wind conditions.
Hover Operating Phase (HOP)
Utilizing the ability to create variable and turbulent airflows, hover tests evaluate the UAS’s stability and energy efficiency. This phase benefits from WindShape’s capability to replicate real-world environmental conditions, providing manufacturers and operators with valuable data on performance and design optimization.
A ‘HOP’ Test Example
- Turbulence Stability Test – Assesses the UAS’s ability to maintain a stable hover in turbulent airflows, replicating unexpected wind shifts.
- Hover Endurance Test – Determines the duration a UAS can hover while subjected to random wind patterns, focusing on battery efficiency and control mechanisms.
Landing Operating Phase (LOP)
Focused on the UAS’s descent and touchdown, this phase leverages the Windshapers precision to test landing accuracy and stability under challenging wind and environmental conditions. WindShape’s technology flexibility in simulating diverse wind scenarios ensures that UAS can safely land in close proximity to people and structures.
A ‘LOP’ Test Example(s):
- Precision Landing Test – Measures the accuracy of UAS landings under simulated wind gusts, ensuring safe touchdown in designated areas.
- Landing Stability in Wind Shear – Evaluates the UAS’s ability to remain stable and control descent speeds when experiencing sudden changes in wind speed and direction.
Each phase, is enhanced by WindShape’s Fan-Array Wind Generators, real-weather generators, and a close-loop data-capture environment ensuring precise simulation and data capture of real-world urban and rural flight conditions. This provides quality validated data-in so that you can make quality decisions to improve UAS and AAM safety, efficiency, and regulatory compliance.
