One for the Pilots here if I may please?
I'm a sucker for airline geeky videos and watching a BA 789 taking off from Mexico, the author stated that as MEX is 7,000 feet above sea level which results on a much higher high take off/rotation speed due to the thinner air? I didn't know this and wondering how this is calculated? Is it x amount of knots for every 1k/5k elevation?
Secondly, are there other airports like this BA fly to?
TIA
Pete
