How do airplanes work

[Dwarf Floyd]

I build an starting lane, build a building to buy a station and runways. But the planes goes in circles and do not start to the other airport. I don't get it.

Your planes must have a clear destination. Check the area nearby your runway to see if there are warning signs on trees or structures too close to your destination runway. Landing obstructions must be removed before your plane will take off. Your destination runway may be too short. Basically, something is wrong with the destination.

plane circles because either runway is too short, trees are in the way, or taxiways are not correct. Likely, you got one-way taxiway issues. It wont land unless it has an exit ramp from the runway to terminal. Check for red triangles, make sure exit ramp is correctly aligned from the runway, and runs smoothly into terminal.

If you drew the taxiways right, there will be no tiny red error triangles, and the yellow directional arrows on the taxiways will all align.

99% of problems with airplane not starting is on the DESTINATION airport, not on the one you are flying from.

Have their been any changes in runway length requirements since you made these tutorial videos? I ask because in your one video you made the beginner runway a length of 4 but noted that was only because you found that more aesthetically pleasing. I did the same. But then when I earned the Dakota from the quest, I cannot use it because it says the runways are too short? (to be clear, my runways are of length 4).
I am so frustrated learning by trial and error, because everything is so expensive, and I don't generate so much green coin income. I have torn down the airports several times.

The length requirements are different for different planes (as much as I know there weren't any changes since the release, but the length has always been different). Sorry I don't know from the top of my head what it is for Dakotas. But you can see he runway length in depot when you are buying planes, It is part of the info there.
