Aerosoft has announced the Douglas DC-8 is now available as a download for Prepar3D version 4.
The package is based on the DC-8-50 series and features a 3D exterior model with animated passenger/cargo doors, control surfaces, thrust reversers and undercarriage. Sound effects, by Turbine Sound Studios, include the distinctive roar of the JT3D powerplants as well as external air cart sounds.
Up front, the virtual cockpit is modelled with 3D instruments and controls for the captain, first officer, and flight engineer. More than 10 systems are simulated with a focus on flying the aircraft accurately using normal procedures. A custom icing code will cause airframe ice accumulation to increase drag and degrade lift while de-icing will gradually remove icing effects.
The powerplants have been modelled with accurate EPR readings to set power for takeoff, climb and cruise. In addition, the aircraft comes with an old-school INS with random drift, DME updating and realistic or fast alignment times. INS waypoints can also be inserted manually, although it is possible to load a standard FSX flight plan. A radar display has been modelled, which shows terrain with three selectable ranges.
Other highlights include rain effects on the cockpit windows using TrueGlass technology by TFDi Design, dynamic landing and taxi lights as well as ground floodlights that illuminate surrounding objects. A detail lighting model for the cockpit includes floodlights for the main panel, pedestal, and engineer’s panel, dome lights, panel back lighting, and instrument lighting with four selectable levels of intensity.
A custom utility can be used for loading/unloading up passengers, cargo and fuel as well as setting the aircraft up in a cold-and-dark state. Performance tables to determine V speeds, power settings, takeoff trim, and stall speeds are also been included.
According to Aerosoft, the DC-8 is initially for Prepar3D version 4 only. The 32-bit version for FSX is expected to follow in May at no additional cost.
