A380 at 39000 ft

Hello guys sorry if im asking too much but what could be the weight of an a380 to proceed FL390 from FL360 i did a step climb

You are getting too wrapped up in specific numbers for various aspects of flight. You need to learn why these numbers are what they are and how they impact your flight. It will make your flight experience much more rewarding.

Going from FL360 to FL390 just means you need to climb slowly.


If you see your plane struggling to maintain your speed aka it starts going down then this is how you would know that you are too heavy. It’s basic but it works.
