As at most airfields with the FIDO system installed, it was used as a last resort, due not only to the high cost of petrol, but also the amount of petrol the system used. On a single burn during December 1944, the system used a massive 188,000 gallons of petrol. At the time Fiskerton was one of only 15 airfields to receive this newly developed system. More activity was to take place at the station on the 2nd January 1944, the airfield became the home of 1514 Beam Approach Training Flight, bringing with them the Airspeed Oxford.
More change was to take place in October 1944, when 52 Base was transferred to 1 Group, Bomber Command on the 7th October; with this the station became a sub-station of 15 Base. However No.49 Sqn remained under the command of 5 Group, and subsequently left the airfield on the 16th October 1944. With this move, it left the station with only the resident BAT flight and a single detachment of No.141 Sqn which had arrived on the 4th September with its Mosquitos, as the only operating aircraft at the airfield. But they were soon joined by the first arrival from 1 Group, No.576 Squadron. They arrived on the 30th October, and only two days later, on the 1st November, they were joined by No.150 Squadron which was formed at the station. With the arrival of both squadrons brought an abundance of Avro Lancasters to the airfield.
During operations from the airfield, a total of 117 Lancaster's were lost from the two resident bomber squadrons.
