Re: Emirates shelves plans to fly to MEX

Just a few thoughts… how interesting is Mexico to Catalans, and how interesting is Catalan culture to Mexicans? The colonial connection is with Spanish culture, not Catalonian, isn't it? I was also thinking that Barcelona's commercial importance has been strong in the past, but in light of the indep...

Re: How the 737 MAX 10 landing gear works

Okay… please bear with me. I have thought about this further, and I can envision how it could be just one oleo. So, I see two separate movements at play here: (1) the purely vertical movement of the oleo, the same as on normal 737 gear, and (2) the rotation of the trailing link to which the wheels/a...

With the MAX10 there seem to be two springs in series. One the normal dampened oleo and the other to extend the trailing link, possibly undampened and surely with a much different spring rate (because the trailing link can simply rest in the stops nearly all of the time (compressed while at the gro...

Re: How the 737 MAX 10 landing gear works

Here’s a question. Have you ever tried to lift a car? There is a certain distance which you can raise the vehicle, but the wheels remain on the ground. It is because of the vehicle’s shocks/struts/springs that this is possible. It is not an active system which senses you pulling up on the car, and t...

Exactly, as the plane approaches Vr, there is significant lift from ground effect and the wing, which starts the plane’s upward movement as shown. Yes, based on watching the video and based on my experience in light aircraft, that's what I think is going on. The lift is already significant at Vr-1,...
