But a key factor often overlooked in the hype about on-demand drone applications is the weather: drone\u2019s cannot and should not fly in all types of weather.<\/p>\n<p>The weather conditions most likely to prevent drone use are precipitation (which can damage electronics), strong winds (which can increase battery usage or even cause drones to lose control) and cold temperatures (which greatly reduce battery performance).<\/p>\n<p>Ambitions to expand on-demand operations hinge on drone\u2019s performing with sufficient up-time to supplement or supplant conventional practices. The viability of using drones for these applications is diminished if weather prevents them from flying.<\/p>\n<p>In our <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/doi.org\/10.1038\/s41598-021-91325-w\">new study<\/a> published in <em>Nature Scientific Reports<\/em>, we examined the impact of precipitation, wind speed and temperature on drone flyability at a global scale.<\/p>\n<figure class=\"align-center \">\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" alt=\"a drone flies carrying a package labelled HUMAN ORGAN\" width=\"600\" height=\"400\" class=\"js-lazy\" src=\"https:\/\/images.theconversation.com\/files\/406586\/original\/file-20210615-15-9ukmqk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\"\/><figcaption><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/thenextweb.com\/news\/#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Feditorial.thenextweb.com%2Ftech%2F2021%2F06%2F21%2Fextreme-weather-a-drones-worst-enemy-syndication%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: Are drones reliable enough for time-sensitive delivery applications?

The most common drone\u2019s used for commercial applications, according to data we obtained from the United States Federal Aviation Administration and drone manufacturers, should not be flown in any precipitation, but can tolerate temperatures between 0 C and 40 C and winds up to 10 metres per second (the equivalent of 36 km\/h).<\/p>\n<p>When compared to 10-year weather data from the 100 most populous cities around the world, these tolerances limit the average flyability of common drone\u2019s to just 10 hours per day. In other words, more often than not, common drone\u2019s cannot fly safely due to adverse weather conditions.<\/p>\n<p>For time-sensitive or emergency drone delivery of medical supplies, a low flyability value is problematic. Waiting for the weather to clear up is not an option. Alternative or conventional modes of delivery will be required to supplement drone operations when the weather is unsuitable.<\/p>\n<p>Less common, weatherproofed drones have a much greater average flyability of 95 per cent and are built to withstand modest precipitation, stronger winds and colder temperatures.<\/p>\n<p>Some cities are located in more or less favourable drone climates. For example, the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a>ly temperate Johannesburg, South Africa, offers high flyability for common (96 per cent) and weatherproofed (100 per cent) drone\u2019s alike. Conversely, the colder and wetter climate of Saint Petersburg, Russia, is inhospitable to common drone\u2019s (two per cent flyability compared to 68 per cent for weatherproofed drone\u2019s).<\/p>\n<p>What degree of weatherproofing do common drone\u2019s need to increase their flyability? Increasing the precipitation and wind speed tolerance to 1 mm\/hr and 15 m\/s, respectively, would significantly improve their average flyability from 40 to 87 per cent.<\/p>\n<p>The flyability estimates in our study are conservative as other factors like dust, icing, wind gusts and turbulence, and meso-scale weather phenomena (that are too small to be captured in a global analysis) were not examined.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Component_and_performance_standards\"><\/span>Component and performance standards<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Although weatherproofing increases flyability, it does not prevent incidents or accidents and does not guarantee safe operations. Some popular weatherproofed drone\u2019s with <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.dem-uk.com\/deltron-enclosures\/news\/what_is_ingress_protection_ip.asp\">ingress protection<\/a> \u2014 the degree to which their interior components are protected from environmental exposure \u2014 and third-party certification have <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.cnn.com\/2020\/01\/10\/uk\/drone-fall-sky-intl-scli-gbr\/index.html\">failed and crashed<\/a>.<\/p>\n<p>Ingress protection could substantially increase flyability according to our study, particularly in regions with frequent precipitation, but we found a critical lack of weather-related standards for drone components and performance testing. This has allowed the drone industry to advance on-demand applications without the rigorous checks and balances found in the piloted aerospace industry.<\/p>\n<p>To safely scale on-demand drone applications, particularly in densely populated urban areas, a defensible and standard set of weather performance tests for drone\u2019s will be required.<\/p>\n<p>Our research demonstrates that weather is a considerable constraint on the widespread adoption of common drone\u2019s for on-demand applications. Future local-scale studies in select cities may help illuminate the appropriate level of weatherproofing needed. In general, however, these engineering efforts will need to be matched by public-safety-oriented regulations to prevent <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.popularmechanics.com\/flight\/drones\/a28774546\/drone-head-collision\/\">potential injuries<\/a> from falling drone\u2019s and their payloads.<!-- Below is The Conversation's page counter tag.
