I call BS... Why is Emirates regularly able to operate JCMach1 Jul 2018 #2

Maybe the planes are designed for more lift to operate there? Moostache Jul 2018 #4

Good guess on lift. Depends on type of plane and length of runway underpants Jul 2018 #8

Long runways. The Velveteen Ocelot Jul 2018 #52

Good question. I'm gathering that it depends on the plane and length of runway underpants Jul 2018 #9

how does hot weather affect it ? JI7 Jul 2018 #3

I looked it up - air density underpants Jul 2018 #6

Heat and airport altitude affect the air which in turn impedes the wing's ability to lift. Stinky The Clown Jul 2018 #7

It also affects the engines ability to make power Major Nikon Jul 2018 #51

Yes. It was, in fact, technically too hot to fly - based on the manufacturers charts. Hassin Bin Sober Jul 2018 #34
