The Douglas DC3 C-47 is the military version of the famous DC3 transport aircraft. Shortly before the Allied invasion, the factories of the Douglas Aircraft Company produced two of them, every hour. At the end of World War II, over 10,000 C-47 rolled from the factory.

With its strength and its exceptional flight characteristics, the Douglas DC-3 has transcended time and needed to be present in Flightgear. Started by Emmanuel Baranger, members of the PAF have done great work on this aircraft. Following different orientations about the aircraft development, members of the PAF have decided to continue the development of the aircraft independently of Mr. Baranger. There is currently two versions of the DC-3 and there are differences. This page is about the presentation of PAF developed version.

As of 22/12/2013 the version distributed through the Flightgear Aircraft download page (Douglas-Dc3_20130107.zip) crashes on at least some computers when trying to operate mixing and propeller levers using the mouse (see [1] bug report). For the version available from the download link the levers can be operated using the typical keys ('m/M' and 'n/N') and so is flyable even though I have still experienced short freezes of a few seconds when looking around too much in the area of the levers.

Features

Dual Control

With the DC-3, dual control is highly developed. It allows to many users to connect to one aircraft in same time. There is one place for copilot (--aircraft=dc-3-copilot) which allows to control entirely the DC-3. All switches and controls are available for the copilot. Then there is 4 places for passenger (--aircraft=dc-3-psg1, --aircraft=dc-3-psg2, --aircraft=dc-3-psg3, --aircraft=dc-3-psg4) which doesn't allows control of the DC-3. You are just onboard et fly with him.

Hydraulic system

Le groupe hydraulique

Hydraulic system of the DC-3 is very complete. He has been create as closely respecting the constructor documentation. The hydraulic system is used for these equipments :

  • Brakes
  • Landing gears
  • Cowl-Flaps
  • Flaps
  • Wipers

In order to use one of these equipment, you need to have at least one engine running in order to have an hydraulic pressure.

Fuel system

The DC-3 is equipped with 2 main tanks and two auxiliary tanks. As in reality, the two auxiliary tanks are not connected to the main tanks. So if you run out of fuel in the main you can switch to the auxiliary tanks with the fuel selector located on the pedestal. You can see the amount of fuel remaining in each tank with fuel gauge and a switch located next to co-pilot.

Electric system

The electric system simule the charge and discharge of battery. When engines are running, batteries are charging. More you use electric equipment, more batteries are discharging.

Paratroopers

The DC-3 has long been used for skydiving, so it is important that they be present. To drop the paratroopers the pilot must open the cargo door (Ctrl + D) then engage the switch "Parachute signal" located on the driver side overhead.

Options

Le menu du DC-3 C47

The DC-3 has a menu of options to customize it to your liking. To make it appear click on "Douglas DC3/C47" menu, then "Options." Options are :

  • Show Yokes = Show/hide Yokes
  • Show Pilot = Show/hide pilot
  • Show Copilot = Show/hide copilot
  • Details High = Show/hide 3D details (rideaux, engines, lights, extincteurs...)
  • Glass reflection = Show/hide reflect shader of windshield
  • Landing light cone = Switch between light cone and plane light about landing light
  • Autostart = Setup DC-3 to start engines. Click on "Autostart" then press key "s" in order to start engines
  • Select version = Choose interior themes
  • Immatriculation = Set aircraft immatriculation

Divers

  • Many animation
  • 3D Cabine
  • Tutorials
  • Real sound of DC-3
  • More than 25 liveries


Aircraft help

Startup

  1. Turn Master Battery ON (situated on the left of the overhead)
  2. Set selectors tanks on their respective main tank (rotate switch situated on the pedestal)
  3. Engage Boost Pump left and right (situated on the right of the overhead)
  4. Set magneto at "both" (situated at the middle of the overhead)
  5. Engage left starter switch then right starter switch (situated on the right of the overhead)
  6. Desengage break parking (Shift + b)

You are now ready to align yourself on the runway.


Take-off

  1. Go to the runway threshold
  2. Make sure the flaps are retracted
  3. Set Cowl-Flaps valves on "Trail" (to the right of copilot)
  4. Release the parking brake (Shift + b)
  5. Align yourself with the track -Make sure you're aligned face to the wind!-. You can unlock the tail wheel by flipping the lever at the bottom of the pedestal from right to left ( l )
  6. Lock the tail wheel by flipping the lever at the bottom of the pedestal from left to right ( l )
  7. Set the mixture on "Auto Rich"
  8. Increase to maximum the propeller pitch
  9. Set full throttle
  10. Gently pull the stick so that the tail of the aircraft stays on the ground a few seconds to the lead in the first few meters of acceleration.
  11. During taking speed you will be very focused to correct the path of the DC-3.
  12. Arrived at 55/60 kts release the handle, the tail will rise.
  13. Now the tail is lifted be extremely focussed on keeping the plane centred on the runway line. Use the rudder and, if necessary, the left and right brake. This part is very tricky but with a little practice it can be done
  14. Continue to take speed to 70-80 kts and then gently pull on the handle.
  15. You begin to leave the ground, begin immediately to increase the trim to facilitate your ascension
