This package contains an update to my previous (ACG) land-based Catalina model (IWM Duxford package) to enable its use on water in FS9, FSX and P3Dv4. Two variations are included: - N427CV, a 1944 Canadian Vickers PBY5A, privately owned and operated from Colorado Springs in the USA. - N9521C, also a Catalina PBY5A but with a nose turret, built by Consolidated in 1943. It represents an aircraft of the US Navy in the historic Pacific Theatre Color scheme and is owned and operated by The Military Aviation Museum, Virginia, USA. The two new models differ quite significantly in detail from the land-based Catalina previously produced. The new models have been re-designed with retractable wing tip floats and the main gear has been removed to enable water operations. The fuselage now has an interior that allows see-through “glass” blisters on either side of the rear fuselage. The texture sheet has been re-designed and the model re-mapped to it to give greater flexibility for future paint variations. These changes mean that the land-based and the new water-based aircraft models and textures are not interchangeable. The aircraft were produced after a request from a colleague at MAIW who is proposing to make some operational water-based scenarios. Consequently, this package, combined for FS9 and FSX/P3Dv4, has been released as “Aircraft-Only” with simple instructions that users can follow to construct water-based AFCADs at locations of their choosing. Flight plans follow the usual format.
