On June 28th, local time, Facebook's drone Aquila launched its first test flight in the Yuma Desert. At first, the flight of the drone was quite successful, but when it landed, it was accidental. In this regard, Facebook explained that when the accident occurred, the drone encountered a strong wind and the right wing structure failed. However, aviation experts disagree with this statement. In their view, Facebook's flight was too reckless because they not only extended the flight test time, but also tried to let the plane land when it encountered strong wind conditions.
The National Traffic Safety Administration's accident investigation report showed that Aquila encountered a strong wind during the landing. At this time, the operator tried to correct the damage caused by the software. However, this operation made the speed of the drone more. fast. This series of errors eventually caused Aquila's 20-foot wing to be broken.
Since Aquila's first test flight was in the desert, the weather conditions such as temperature and wind were not ideal. It is reported that Aquila flew to the sky at 6 o'clock on the day of the test flight. However, as time progressed, the temperature of the pilot began to rise, which aggravated the changes in wind conditions. In other words, the longer Aquila stays in the air, the more risk it will face. At the time, however, Facebook let the drone fly in the air for 90 minutes, three times longer than originally planned. time.
At 7:37, Facebook decided to let Aquila land, but at the time they detected a wind between 12 konts and 18 knots, which is beyond the range that the drone can withstand (default is 10 konts), but Facebook Still decided to continue the landing.
Aquila software development participant Yael Maguire told the media that they had never tested the wind on the day of the test flight in 1,000 computer simulations.
Francesca Favaro, assistant professor of aviation at San Jose State University, points out that no flight should attempt to be deployed outside or at the edge of a pre-set condition unless it has been indicated at the outset that it is not intended to test the maximum limits of the actual design. In addition, she also said that if she is replaced by her, she will never let the drone land in such weather conditions.
That being the case, why is Facebook going to land under such dangerous conditions? The company has repeatedly assumed that Aquila was damaged during the landing and that the prototype will no longer have a chance to take off in the future. In their eyes, landing is not their optimization. What they need to do is how to make this drone capable of completing a 90-day mission.
In addition, Facebook also said that in view of security issues, Aquila is not ready to fly over densely populated areas.
