...I have searched the forums and can't find out. I can't guess either - runway limit doesn't seem to affect plane behaviour at all.
I thought it would be the speed that planes move when in a runway's traffic pattern, but apparently not...
Thanks for your help! :D
300km/h is possibly the average speed between take off and landing speeds between various aircraft in various weather conditions and configurations.
If runway speed limit affects anything, I would assume it would be the speed when actually on the runway.

Apparently not, testing with Concorde, it easily moves along the runway at a speed greater than the limit. Taxiing ignores limits too - about 65 km/h on both runways and taxiways (which incidentally have a "limit" of only 50 km/h).
But it tries to stay in the limit.
Airplane ways are quite useless, some changes are needed to make them more usable. Right now you don't need to use the latest ways or have a runaway bigger than 3 tiles.
The plane dat should include or the takeoff speed or the min tile lenght to takeoff. Takeoff speed would be better because it would force you to upgrade to a faster runaway and such info is included on the plane specs.
And to fix the upgrading of taxiways for larger aircraft you could impose some weight limit like for bridges and the like
Ironically, in real life, some of the heaviest planes don't require better runways and taxiways than some of the lightest. They require more room, though, but vehicles in Simutrans can't occupy more than one tile, except probably lengthwise.
Well, you don't see 777s using grass runways and taxiways. Since grass and concrete are the only 2 way types available, it would make sense to upgrade to concrete later on. Basically any aircraft with trike gear on Simutrans is too large to be used on grass. So the weight could be set accordingly there.

I wasn't thinking of 777s, or even planes with trike gear. But I'm sure the planes I'm thinking about exist in some pak set or add-on. It actually seems that Zeppeliners were about as heavy as a medium passenger jet, but it shouldn't require concrete.
In real life, the main problem with grass is that it does not handle heavy planes well at a stand still, because of the high concentration of weight on few wheels.
It's not ideal landing and taking off on grass either, but it is possible and usually only done so in emergencies.
^^ what he said. Those older planes were built to use grass strips, whereas the newer aircraft (starting in the 50s or so) are designed primarily for concrete use. Zeppelins don't need to taxi and float at their moor anyway, so can ignore the weight restrictions. But all those larger aircraft, even as far back as the DC-4 and Constellation, will need concrete.
My point is that Simutrans can't use weight (alone) to determine which ways an aircraft can use. Airplanes either need a specific attribute for which ways it can use that is different from weight, such as axle load, or an attribute that tells Simutrans to ignore weight when determining way suitability.
So you just fixed the problem. Those with high enough axle load (or whatever is used to determine way use) would have to use concrete and any lighter-than-air craft or helicopters can ignore that
And what about takeoff speed?
Plane won't takeoff without reaching the speed.
On 96comic I've made all small planes takeoff after 6 tiles and all the big on 8 (loaded).
But coding this looks complicated, specially the routing code. That would require checking if there's enough room to takeoff.
there is an experimental feature that can restrict airplanes to use runways at least x meters long.
But since standard paksets use 1km/tile, most airplanes would be able to take off in 4 tiles.
