Did you just google those terms? LOL.
Now listen to me, carefully.
You have stated that the runway length is just 400m more than what a 737 requires to land. Wrong. It's...
more... more than 1000m more than what a 737 requires to land safely.
Secondly, you have stated: "Even if Boeing747 land then it would be an emergency landing." THis statement of yours underlines the amount of knowledge you have regarding the aviation industry.
You think this is a bus that it'll land on an uncertified runway?
It's clear that you're desperately trying to get some attention, which I can understand. But when somebody corrects you, try to learn from what they're saying rather than blowing your own trumpet. Anyway, if you want to learn more about aviation, head over to forums such as pprune, airlinepilotforums, flyer forums etc. Cheers.
