Sami,
With the the most recent log change:
Medium Cargo can now be transported also by freighter aircraft of size class medium and upwards. New full definition is: "Medium Cargo - Requires aircraft of size class 'Large' or larger, or a dedicated freighter aircraft (cargo only) of size class 'Medium' or larger"
This is a great step in making medium class cargo aircraft more useful.
That said, there are class one airports out there that have a reasonable amount of cargo to be hauled. Medium class is unable to carry heavy cargo, thus these airports are unable to reach there full demand potential.
I think allowing large,
freighter only class aircraft into these airports will solve this issue as we move forward with cargo CBD.
