Hi Pamplinas,
Could you tell me exactly which airports have been decommissioned. What are the statistics of these airfields ? (IFR VFR number of passengers).
In France we used to have a rule to decide if an aeronautical study should be undertaken to revise the type of service (ATC or AFIS). I don't know if this rule is still valid ...
coefficient K = I/4000 + M/15000 + PAX/100000
(I = IFR M=IFR+VFR PAX=Passengers)
If K < 1.3 then this airfield should be AFIS
If K > 1.3 then this airfield should be controlled
