Hello

I have done some work using the manuals of the aircraft. I calculated all the minimum length of the runway, according to engine power and weight of aircraft that are included in pak128brit.
I used as reference features "ISA" (sea level, 0 degrees Celsius, dry track). This will get the lengths the lowest anywhere. The values ​​can be recalculated on an average temperature of 10 degrees centigrade (which is the average temperature of Heatrow) amplifying of 10%.
Looking at the data can be seen, however, that the 747 version 100 and 200 have a length of the track particlarmente high. The problem is that with more than 400 passengers the plane was overloaded (can not fly), I thought (if you agree) to use a more powerful variant of the two planes that should provide better performance.

I will fix versions in github, after understanding (according to you) how to act towards the 747 and 10% increase.

Giuseppe,

thank you very much for this - it is much appreciated. Your work on the aviation side of things over the years has been very helpful indeed!

I think that a 10C based length would probably be more realistic for British conditions than 0C. As for the 747s - it is probably reasonable to expect such enormous aircraft to have a very long runway length requirement, so there is no need to change this, I think.

Thank you for your work!

The pilots will normally reduce fuel on board, if the airplane is too heavy for shorter runways. Sometimes, they may also unload luggage to lighten up the airplane. It's usually not a problem, because airports with smaller runways only serve short and medium distance destinations.

It should be fine in simutrans, since the airport will be properly big for big airplanes.  :D
