询问专家：优化BVLOS

What will be the impact of beyond visual line of sight (BVLOS) on the application of drones in the geospatial surveying profession? At 'GIM International', we received this question from one of our readers and forwarded it to Pierre-Alain Marchand, who is employed as R&D regulatory compliance manager at senseFly. The Switzerland-based company is the manufacturer of the renowned eBee and eBee X, UAVs that are commonly used by geospatial surveyors.

BVLOS operations have progressed in leaps and bounds in recent years, thanks to ongoing trials, demos and data collection that have been key in facilitating progress. As an industry, we’re constantly learning and gathering more highly geoaccurate data and insight as to how we can optimize BVLOS in UAV operations.

This process of learning has also enabled unmanned aerial vehicle (UAV or ‘drone’) technology itself to become more advanced. This has seen fixed-wing drones become better equipped for BVLOS operations, offering better batteries and motors and safe airframes that have been verified through rigorous impact testing. As a result, many drones now have the endurance to enable users to safely fly further and map larger areas, broadening the potential for more complex BVLOS applications and offering cost, time and operational efficiencies. This is true across the globe, where operators in more countries are seeing BVLOS becoming increasingly accessible. Last year, for instance, the national civil aviation authority of Brazil (ANAC) approved BVLOS flights to be carried out for the first time in the country’s history, marking a pivotal point in Brazil’s commercial drone industry.

很明显，我们拥有的数据和知识越多，我们就越接近建立强大的框架和定义风险模型来塑造安全，合适的BVLOS操作。这将是促进更大的公众接受和可扩展性，以扩大地理空间专业人员的机会，这将是关键。正如我们所看到的，下一步是达到人类可以在自主BVLOS飞行中扮演管理角色而不是试行的位置。他们将得到更复杂的检测和避免系统和通信技术的支持，以确保与其他空中流量更安全，更平滑。在过去的十年中，无人机行业已经显着发展，但是捕获BVLOS礼物的机会将使固定翼无人机技术真正蓬勃发展。通过对授权机构的试验和合作伙伴关系的持续承诺收集更多数据将是支持安全BVLOS运营的法规的组成部分。

监管前景已经是积极的。欧洲法规以及加拿大运输公司和美国联邦航空管理局（FAA）实施的法律，旨在朝着更好地适应BVLOS飞行方向。我相信这种接受将是BVLOS运营和全球地理空间专业人员的重要推动力。
