Last week we reported that the Trail airport (CAD4) in southern British Columbia was to close effective March 30, and that those wishing to access the airport would need to request permission 24 hours in advance (PPR). Updated information from the City of Trail indicates that the prior notice requirement is in fact one hour, as per the Nav Canada NOTAM.
