Let us know what you think of it 😉

Great link, thanks. Nice data review of the last 40 years. from 90-99 we had ratio of 1.6 incidents with RTO.

Have one question though, RTO deploys automatically when throttle lever goes down above 80knts. Do sopilers and rev.thrust go up as well as max brake, or only the brakes? And another, do nose wheels have brakes, or only main?

Depends on type but generally if both are armed you will get brakes and spoilers. Reverse thrust must be selected manually. Problem with auto reverse thrust could be assymetric thrust with an engine out therefore remaining straight initially could be a problem.

Only main wheels have brakes.

Nice post, very interesting. 🙂

thanks, I have another question then. Do you remember that incident with A320 at KLAX few months ago that was transmitted live at CNN? I think it was jetblue airlines or similar, with the nose wheel stuck 90° to the runway. He landed safely only with few sparks and damaged front gear etc., but why captain decided not to use the rev.thrust, especially when it was an emergency landing? wasn't this too risky, in case he'd overrun or something?

In a situation where the nosewheel is either down and not locked or at 90 degrees you need to keep the weight off the nosewheel...and keep the nosewheel off the runway for as long as possible. Landing distance calculations is something they would certainly account for but in this case the runway was long enough to not warrant use of immediate reverse thrust....probably did not use brakes either initially. Using reverse would bring the nose down firmly onto the runway. Think about whay happens in a car when you apply the brakes kinetic energy etc.
Hope this helps.
