This was an issue on our end where helipad starts were following the same rules as runway starts for number field (1-36 and cardinal positions North/North-West/etc).
It has been addressed and now helipad starts number only accept numerical values, as it should. The documentation should be updated pretty soon.
I am not sure how you got this XML as the Scenery Editor doesn’t write such start number anyway, did you perhaps edited it by hand ? Please let me know so we can fix any remaining issue about this.
Hi Melvin! It’s from an older build so not sure anymore where is actually originates from. What I can say is for let’s say 50% certainty is that the Scenery Editor didn’t update these entries when re-saving the airport in MSFS2024.
