Re: Understanding Emergency Descent Altitudes

I have too wondered how this profile is construed - reaching FL140 within the time oxygen generators are working and continuing on FL140 for 30 minutes without oxygen is quite understandable. What I don’t quite understand are these intermediate stops for a few minutes (FL290 and FL250 in the exampl...

Hello, I'm trying to understand how altitudes are corrected during emergency descents where obstacles are present, and temperature and QNH is below ISA. I've been looking at an emergency descent profile from an Airbus FCOM that gives a total of 2.5 min until FL290 needs to be reached, 7 min until F...

Re: airplane gliding

Be surprised. The Boeing Dual Eng Fail/Stall checklists do not give any kind of gliding guidance to the crew. The checklist assumes you get at least one engine started and have a nice day.

Re: airplane gliding

Modern jetliners like the 777 have at least a 20:1 glide ratio. The 787 glide ratio is supposedly so high it’s proprietary information. I don’t know the exact number.
