In context of the paper, "high-speed gravitationally accelerated dive following fuel starvation", it bears mentioning the L/D ratio of a 777 is around 20. Which means if you lose power at 35,000 feet, you can have at most 132 miles of glide to the surface if well piloted.

- gymbeaux 2y agoWhat are the assumptions for the “132 miles” figure? At the very least wind is going to affect that- if you’re in a headwind you could probably make it closer to 150 miles (albeit not a huge gain).
- imglorp 2y agoYeah that's why I said at most, so assuming still air and perfect piloting. The worst case is lawn dart, 0 glide. 35000 ft x 20 ratio x 1/5280 mi/ft
- egormakarov 2y agoIt's other way around, with headwind you will get less distance over ground
