Parse CRCO Airspace Charging Zone format

parse_airspace_crco reads the airspace CRCO format and returns a tibble where each row describes an airspace. The airspace file can be found on EUROCONTROL website.

Each airspace in CRCO format is described by:

1. Airspace description (one row):

   • nb_point the number of points

   • latitude the latitude (of the label)

   • longitude the longitude (of the label)

   • flights

   • bottom_level low level of the volume (flight level)

   • top_level high level of the volume (flight level)

   • surface

   • sector_num

   • flight time

   • traffic density

   • x mileage

   • rte extens.

   • value 1

   • value 2

   • name airspace name/code

2. latitude longitude: coordinates (nb_point rows in minutes decimal)
