This has to do with making sure the remote pilot always has a secure and solid radio link with the aircraft. It\u2019s that link that allows the pilot to send commands to maintain control of, and receive data back, from the drone.<\/p>\n\n\n\n<p>\u201cSecure and solid\u201d in this case meant proving an aircraft\u2019s radios couldn\u2019t be jammed by bad guys or an accident \u2013 or that weather or topography wouldn\u2019t affect the quality of the radio signal, and enough of the best frequencies were available to use.<\/p>\n\n\n\n<p>Again, it wasn\u2019t NASA\u2019s job to invent the hardware that could do all these things. But it was our job to help put this hardware through the wringer and use the resulting information to come up with a proposed set of Minimum Operational Performance Standards (MOPS) mentioned in the <a href=\"https:\/\/www.nasa.gov\/aeroresearch\/a-story-for-axel-nasa-drone-projects-achieve-critical-early-work\">first part of the story<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Phased Approach<\/strong><\/h2>\n\n\n\n<p>Ultimately the UAS in the NAS project completed its work in two phases.<\/p>\n\n\n\n<p>Phase 1 began in 2011 and primarily looked at drones operating at altitudes of 18,000 feet and higher. Airplanes at this height are in constant contact with air traffic controllers, must file flight plans, and follow long-established rules when in this airspace.<\/p>\n\n\n\n<p>Phase 2 began in 2016 and considered drone operations in the altitude range of 500 feet to 10,000 feet high. Airplanes in this airspace are more likely to be General Aviation aircraft, many of which don\u2019t need to file flight plans or interact with air traffic control.<\/p>\n\n\n\n<p>Remember Mauricio Rivas, my friend who managed the UAS in the NAS project?<\/p>\n\n\n\n<p>He told me this made writing a MOPS for this airspace a bit more challenging. With more aircraft of so many different types flying in this airspace without someone always directing the traffic, the MOPS had more scenarios to account for to avoid potential trouble.<\/p>\n\n\n\n<p>Just like every college course ends with a final exam \u2013 something, Axel, I expect you will experience in about 18 years or so \u2013 each of these UAS in the NAS phases ended with a big test.<\/p>\n\n\n\n<p>For Phase 1 the final test happened in June of 2018 and resulted in <a href=\"https:\/\/www.nasa.gov\/press-release\/nasa-flies-large-unmanned-aircraft-in-public-airspace-without-chase-plane-for-first\">making aviation history<\/a>.<\/p>\n\n\n\n<p>The whole point of the UAS in the NAS project was to enable these larger, remotely piloted drones to make a flight just like any other piloted airplane flying in commercial airspace. The final test for Phase 1 saw that very thing happen.<\/p>\n\n\n\n<p>What was unique and history making was the fact that the drone \u2013 NASA\u2019s <a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/news\/FactSheets\/FS-097-DFRC.html\">Ikhana<\/a> UAS in this case \u2013 made the flight without a piloted aircraft flying nearby to keep an eye on it. All previous flight tests were required by FAA rules to have this \u201cchase\u201d plane.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/a001_l005_0921r9_05.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1152\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/a001_l005_0921r9_05.jpg?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"The Bell Textron Inc.

During the flight, air traffic controllers talked to the remote pilot as though the pilot was on the airplane.<\/p>\n\n\n\n<p>The controllers later said the flight sounded and looked on their displays like any other flight.<\/p>\n\n\n\n<p>And since that was the whole point \u2013 success!<\/p>\n\n\n\n<p>\u201cThey didn\u2019t have any idea the pilot was on the ground. This was a really significant achievement, not just because it was a cool thing to do, but it was historic. The fact that the controllers didn\u2019t know it was unmanned, that was just icing on the cake.\u201d<\/p>\n\n\n\n<p>That\u2019s what <a href=\"https:\/\/www.nasa.gov\/aeroresearch\/lee-noble-bio\">Lee Noble<\/a> said to me about the flight. He\u2019s director of the <a href=\"https:\/\/www.nasa.gov\/aeroresearch\/programs\/iasp\">Integrated Aviation Systems Program<\/a>, which is the program that oversaw the UAS in the NAS project.<\/p>\n\n\n\n<p>The finals for Phase 2 weren\u2019t historic to the same extent, but Lee said they were just as significant.<\/p>\n\n\n\n<p>For this final part of the project, which took place in 2020, two companies partnered with NASA to participate in what was called a <a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/ps-02803_0320_uas_nas_sio_demo.pdf?emrc=0a2390\">Systems Integration and Operationalization Demonstration Activity<\/a>, or SIO. A mouthful, Axel, I know, but easy to understand.<\/p>\n\n\n\n<p>The basic idea was for each company to take all they had learned so far about DAA and C2 and demonstrate the ability to fly its drone on a specific mission that would be an example of a possible future use for a commercial UAS flight within the NAS.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/features\/SIO-first-flight-2020.html\">first SIO flight <\/a>was in April 2020. General Atomic Aeronautical Systems flew its SkyGuardian UAS over southern California on an infrastructure inspection mission from 10,000 feet high.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/features\/second-sio-demo-flight.html\">second SIO<\/a> flight was in September 2020, less than two weeks after you were born. Bell Textron flew its APT 70 UAS near Fort Worth, Texas on a simulated urgent medical transport mission.<\/p>\n\n\n\n<p>In both cases the remote pilots had to interact with air traffic controllers as they navigated flying through busy airspace. And in both cases these final exams of Phase 2 were given passing marks.<\/p>\n\n\n\n<p>Here\u2019s how Lee explained the importance of the SIO\u2019s:<\/p>\n\n\n\n<p>\u201cBeyond the SIO flights themselves, the idea was to coordinate with our partners and the FAA as they worked through the process that would lead to certifying these systems. The partners learned some things about what was important to the FAA, and the FAA learned some things about how the partners viewed the process and what they struggled with along the way.\u201d<\/p>\n\n\n\n<p>Incidentally, a third company, American Aerospace Technologies, was planning to conduct a third SIO before the UAS in the NAS project officially ended last year, but various issues <a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/features\/gas-pipeline-inspections-simulated.html\">delayed it into 2021<\/a>.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1041\" height=\"658\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?w=1041\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"American Aerospace Technologies Inc.\u2019s AiRanger unmanned aircraft system (UAS) flew with the Citabria plane\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg 1041w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?resize=300,190 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?resize=768,485 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?resize=1024,647 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?resize=400,253 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?resize=600,379 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/73a06225.jpg?resize=900,569 900w\" sizes=\"(max-width: 1041px) 100vw, 1041px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">American Aerospace Technologies Inc.\u2019s AiRanger UAS aircraft (top) flies a simulated petroleum pipeline survey mission in February 2021 as part of a NASA Systems Integration and Operationalization demonstration.
