Research Results

Research findings and results become available as soon as the research is released to the public.


The research team analyzed the ASTM F38 standards to identify gaps in the standards as well as compliance issues that manufacturers and operators may encounter when using the standards as a basis for certification through 14 CFR 21.17(b).

ASSURE UAS Detect and Avoid Requirements Necessary for Limited Beyond Visual Line of Sight (BVLOS) Operations

Beyond-Visual-Line-of-Sight (BVLOS) is similar to Extended-Visual-Line-of Sight (EVLOS) and other operations where the small unmanned aerial systems (sUAS) is not in the immediate proximity of the operator. In general, BVLOS is an operating environment where the sUAS is out of sight due to distance and the limitation of the human visual system. This report captures one specific element related to assessing this potential flight space; the assessment of the Radio-Line-of-Sight (RLOS) coverage. The goal was the assessment of the RLOS connection for sUAS through testing. This connection element is key to ensuring safe operations, specifically if flying BVLOS.

ASSURE UAS Airborne Collision Severity Evaluation

The UAS Airborne Severity Evaluation research findings document the UAS platform characteristics related to the severity of Unmanned Aerial Systems air-to-air collisions with a commercial transport jet or business jet.

ASSURE UAS Ground Collision Severity Evaluation

The UAS Ground Severity Evaluation research findings document the UAS platform characteristics related to the severity of Unmanned Aerial Systems ground collision based upon the literature research of over 300 publications from the automotive industry, consumer battery market, toy standards and other fields. The team reviewed available research and techniques used to address blunt force trauma, penetration injuries, and lacerations as the most significant threats to the public and crews operating Small Unmanned Aerial System (sUAS) platforms.

ASSURE UAS Ground Collision Severity Evaluation 2017-2019

This study expands ASSURE's previous Ground Collision research to farther assess injury potential of various small UAS (sUAS) of different material properties and construction. Tests were conducted with 16 different multi-rotor and fixed-wing sUAS and objects (payloads, wood blocks, and batteries) with weights ranging from 0.75 - 13.2 pounds.

ASSURE UAS Maintenance, Modification, Repair, Inspection, Training, and Certification Considerations

Kansas State University (KSU), Embry-Riddle Aeronautical (ERAU), Montana State University (MSU), and Northland Community Technical College (NCTC) conducted a two-year research project to identify the requirements and considerations for UAS maintenance, modification, repair, inspection, training and technician certification by building upon the existing body of knowledge for sustaining UAS. The research team collected and consolidated current UAS practices from industry and developed recommended requirements to ensure that risks of maintenance-induced failures are minimized.

ASSURE UAS Surveillance Criticality

The Surveillance Criticality research team has completed a set of analyses using a formalized structure that enables the ASSURE team to offer further research into DAA surveillance criticality analysis. This structure provides the team the tools to work with industry partners to evaluate technology performance against standards and other systems, while also providing the Federal Aviation Administration, RTCA, and others with a research methodology for expanding into new operating scenarios and equipage configurations.

ASSURE UAS Noise Measurement

FAA's Office of Environment and Energy (AEE) is supporting the Federal Aviation Administration Unmanned Aircraft Systems (UAS) Integration Office to ensure the safe, efficient and timely integration of UAS into the United States' National Airspace System (NAS). In order to fulfill this mission, the FAA is developing UAS standards, procedures and regulatory products. The primary control over aircraft source noise is the noise certification process, which is the responsibility of AEE within the FAA. This document describes the TigerShark UAS level flyover noise measurements that were performed at Griffiss International Airport, Rome, New York, on May 17, 2016.

ASSURE UAS Recommendations for Minimum UAS Control Station Standards and Guidelines

The objective of the work was to develop recommendations for minimum unmanned aircraft system (UAS) control station standards and guidelines. The recommendations focused on operation of fixed-wing unmanned aircraft (UA) larger than 55 lb operated beyond visual line of sight in an integrated National Airspace System (NAS). A four-step approach was taken, including (1) development of recommendations for minimum human-automation function allocation, (2) identification of minimum information requirements for safe UAS operation in the NAS, (3) storyboard development, and (4) cognitive walkthrough of the storyboards.

ASSURE UAS Low Altitude Safety Case Study

The FAA requested research to explore the data requirements and analysis needed to submit a Part 107 waiver for flight over people. The submission of the waiver in conjunction with the research allowed the team to exercise the approval process and define standards that might be used to improve the waiver process for more challenging waivers such as operations meeting the Category 3 and 4 Performance Standards defined by the Micro-ARC Final Report. The research led to successful submission of a Part 107 waiver for flight over people for the Phantom 3 Standard and Advanced, including substantiation data to meet the Category 4 Performance Standards defined by the Micro-ARC Final Report 1. The waiver and this final report include new methodologies for determining safety thresholds other than those used by the Range Commanders Council (RCC).

ASSURE UAS Minority Outreach: STEM

Under the Federal Aviation Administration’s ASSURE UAS Center of Excellence, a team of two Universities were tasked with providing two STEM Outreach approaches to the FAA that use UAS's as the central learning platform. The target of this outreach are minority or underserved students. The two Universities tasked with this UAS outreach were Tuskegee University which can reach out to a predominantly African-American student population, and the New Mexico State University (NMSU) that can reach out to predominantly Hispanic and Native American student populations. The approach for all of the activities focused on STEM education using UAS or drones as the central learning platform.
