When I approach airports or take off from one, I see that the runway abbreviations are red, orange or green, what is this all about?
When landing, the airplane often swings strangely from top to bottom, even though I have the exact landing speed
And I don’t know how it is with your A340-600, but no matter how light I make the plane, I fly with the same number of seats as the respective airline and I make the cargo according to the baggage limits of the airlines - something like that. But I still never run out of fuel, and I know that I have to take very little cargo for long-haul/ultralong-haul flights because of the comparatively high fuel consumption. Yesterday I flew from Munich to Honolulu and despite the original number of seats and Lufthansa’s luggage limits, I still didn’t make it to my destination.
In this case, I only had 150 passengers + 16 crew members = 166 people and 3 tons of cargo, but it still wasn’t enough, even though the plane was fully fueled.
Last question: I often start the plane with only one engine to save fuel, regardless of the take-off weight. I have the auto-coordination on, but often the plane doesn’t roll properly to the right or left and then the “BRK” sign always comes up and the plane slows down, even more thrust doesn’t help, what should I do?
For your first question, the colors of the runways are the wind direction, green = headwind. orange = crosswind. red = tailwind. I’m afraid I can’t help you with your other questions tho, not sure.
For example, if I have wind from 90 degrees and a runway with, for example, 15L and 20L, which one do I take because it is said that you should take off with the tailwind and not against the wind in normal cases?
you actually want to takeoff in a headwind. in weather reports wind is always where it’s coming from. So if wind is 090, then runway 09 would be a direct headwind. So in this case runway 15L would be the preferred runway
The a340 is an older aircraft so the flight physics might not be perfect. On top of that it is a 4 engine aircraft so double the fuel needed. As for moving up to down it might have to do with trim, flaps or approach settings.
A340 kinda weird. I don’t have the numbers on me but I’d suspect an A340 would have issues making that flight with any load whatsoever. I think its max range is 18 hours and change carrying nothing and that’s if you’re flying the more efficient low altitudes like FL280 which you probably aren’t.
Update: at your load the max endurance is 17.5 hours which should be okay if you’re flying at FL280 and 300 (most efficient) but that number will decrease rapidly if you’re flying any higher (at FL320 it’s already sub 17 hours and I suspect by FL360 it’s probably closer to 15.5 or 16)

Maybe you’re too slow on final? Try landing at 160kts until 4NM final (that should be about 1300ft AGL) then reduce your speed depending on your aircraft. Most aircrafts approach and flare at about 125-140kts.

What about your flight profiles (IAS, VS, and altitude)? If you’re cruising at M0.82, there should be no problem. You might want to take a look at this website. And perhaps you need the fuel planner as well. Lately I often fly on >80% load and had no problem. Just stick to the flight profiles and you’ll be doing good.

You were activating rudder brake by dragging the rudder down. If you only wish to turn left/right, don’t drag the rudder down too much.
I actually always fly the plane up to its maximum altitude. But what you mean contradicts the actual fact that airplanes consume less fuel the higher they fly?
VS were up to 5000ft 1500 with 215kt, up to 15000ft 1000; with 250kt and then 290kt up to 24,000ft and up to 30000ft 800 with Mach 0.81. I then climbed higher and higher the lighter the plane became up to the maximum flight altitude of 42100ft, cruising speed Mach 0.82
