That went well, now to not forget I made a second an third airport, the third had two runways so I expanded the tsc with
endpoint 3 and 4, also threshold an name, that was wrong, you have to copy and paste the whole section and give the
runway element number 1, were the first runway is 0, looks like this:
<[list_tmsimulator_runway][runways][]
