A model of Shaanxi's Ibis Shadow 60 cargo UAV on display at a low-altitude economy trade show. Take-off weight is over 60 tons, basically an unmanned variant of Y-8/Y-9.
Looks like they may have already flight tested this large drone, if the words on the screens are the real test result.
What were shown on the screens:-
1. In Xi'an Xianyang airport - 海拔高度Sea Level 479M, 飞行重量 Flight or Take-Off Weight 61 ton, 起飞滑跑距离 Runway Take-off Distance 1,239M
2. In Lhasa Gonggar airport, seal level 3,569M, TOW 48T, runway T/O distance 2,613M
3. In Ezhou Huahu airport, sea level 21M, TOW 51T, runway T/O distance 790M
The precise detail of the runway take-off distance indicate these are likely real test results.
