In order to guarantee availability all year round, a single aircraft would not suffice in any area. Three helicopters would have to be assigned to the task to allow for one on routine maintenance and one of the other two helicopters developing a fault or anything like that. It is not a question of basing one helicopter there. One would have to put in a back-up of two other helicopters and it would also mean moving some of the existing Air Corps squadrons, together with supporting technical and administrative personnel, to that location. In addition, hangars and stores would have to be provided in order to guarantee serviceability. The sources for this type of service are not available at this time.
