| 摘要： | Unmanned Aircraft System (UAS) operations in the National Airspace System (NAS) are rapidly increasing, and the trend is expected to continue as regulations are refined to allow broader access to the airspace. The unique characteristics of UAS (e.g., extensive operations in populated areas at altitudes below 500 feet, speed capability, and control systems) may drive the need for new and unique operational strategies, many of which are highly dependent on weather conditions. A companion Lincoln Laboratory report (ATC-437, 鈥淧reliminary Weather Information Gaps for UAS Operations鈥? identified initial gaps in the ability of current weather products to meet the needs of UAS operations. As discussed in that report, there are several trends in the information gaps that surfaced repeatedly. A key item was the availability of weather observations and forecasts tailored for on-airport operations that are not necessarily sufficient for off-airport operations. Surveyed users indicated that airport-specific weather information (e.g., METAR, TAFs, etc.) do not readily translate to conditions at remote launch locations, which may be 10鈥?0 miles from the nearest airport, and are influenced by local terrain, vegetation, and water sources. Moreover, the results show that significantly less weather information is available to support low-altitude flight than for typical manned-flight profiles. Beyond Visual Line of Sight (BVLOS) operations were found to have higher need for weather forecasts, uncertainty information, and contingency planning than Visual Line of Sight (VLOS) operations. Furthermore, the study identified specific gaps related to how the airspace should be managed to mitigate safety and efficiency impacts to UAS operations. Building off of that work, this report summarizes the development of a proposed initial roadmap for research to fill the gaps that were identified. The research roadmap presented here is composed of research recommendations that are derived from the identified weather information gaps. In total, there are 14 specific recommendations that define the roadmap. The first two recommendations are not explicitly tied to specific gaps; rather they are based on lessons learned through the course of research in this study. The remaining recommendations are provided in priority order based on their overall significance to the operation, the maturity of the operation, and any dependence among other recommendations. |
