Hello fellow pilots from 2020 - this is 2023 speaking ;)
The recent versions of Sky Dolly introduced the „Location“ module that lets you capture, add, edit and teleport to your own custom locations. Including support for „cold and dark“ starts. Useful e.g. when you want to define your own helipad or airstrip without „parking“.
You can either „capture“ the current location in MSFS, or simply paste GPS coordinates (in various DMS and decimal number formats) into the location table.
