The Chinese civil aviation regulator CAAC today released the draft of the new Part 23 certification document. Some highlights include: 1. it has a new section (H section on page 51) for electric airplane which is for the first time in CAAC Part 23 certification rulemaking. 2. rename Part 23 to “normal airplane” consolidating “normal”, “aerobatic”, “utility” and “commuter” category into “normal” in existing Part 23 3.define airplane certification requirement by seat number and performance, not by weight.

In general the CAAC new part 23 is similar to EASA new Part 23 in many aspects, which is expected. What’s especially interesting is that it’s encouraging to see CAAC is making real rulemaking efforts for electric airplane certification even though the H section in the draft appears to be lack of many important details. CAAC is inviting public opinion on this draft until 26 March 2020.
On September 14 Volocopter made its urban flight debut at the Mercedes-Benz Museum in Stuttgart. The flight demo was a part of the event “Vision Smart City — Experience future mobility today” held during the weekend. The flight lasted near 4 minutes at about 30 meters altitude. The video of the complete flight from takeoff to landing is below (you may want to turn up the sound volumn to listen to the sound: https://www.youtube.com/watch?time_continue=16&v=mH1zk0KOFho
One noticeable thing was the low noise level of Volocopter which claims 65 decibel at 75 meters. This noise level is comparable with small helicopters’ noise level at 500 meters and is about the same as the background road noise in urban environment.
