There are few things to say
about how to fly an aircraft or its procedures. Like in those glorious times,
it is better that each person should discover its tricks and behaviors. It is
just necessary to consider that due to its weight, the weak power of its
engines and its slowness of response, the movements must be previously
anticipated. Due to the complexity of the real aircraft’s systems, especially
those referred to the flight mechanism, we have had to simplify them as much as
possible for their use in FS.
Take-off speed is around 160
km/h. For the take-off setting, keeping the rpm inside the yellow area, it will take us a
few minutes to reach it, depending, naturally, on the gross weight of the
aircraft. Before taking off, the trim must be totally elevated and once it
speeds up, we will be able to check the tendency in case it is very accentuated. Everything has to be done by intuition
because of the lack
of any kind of indication.
Once we are flying, and after
having reduced throttle to around 2150 rpm depending on the weight, the
cruising speed must be kept from 185 to 190 km/h. At this speed, the fuel
consumption is about 1700 liters/hour, so each tank gives an
autonomy of about four or five hours. Back-up lights will turn on when
we reach the 10% of capacity, about 800 liters.
To land on the sea, it
throttles down to 2000 rpm, and the aircraft will begin to descend. We
stabilize the nose using the trim, and, slowly, we will finally land.
We have installed an
automatic pilot, although the original aircraft did not have one, in order to
make long-distance flights less boring. Not to make it too simple, it does not
stay at a determined altitude but it affects the aircraft response. As time
goes by and the fuel is consumed, it will be necessary to vary that attitude by
descending the nose to maintain the flight altitude.
It also has the option of
keeping the direction, but before connecting the automatic pilot, it is
necessary to reach the fixed route, and then, line it up in the route display.
If we connect the automatic pilot and make it guide the aircraft, it will start
to swing making the flight almost impossible. It must be because of some kind
of incompatibility between the instrument and the aircraft which we have not been
able to solve. Any suggestion or help you can give us will be appreciated. More
information about the automatic pilot can be found in FS2004 as it is used in
the same way as the original DC3 aircraft.
1.
Magnetic compass.
2.
Turn indicator.
3.
Vertical speed indicator:
4.
Barometric altimeter: Clicking the inner roulette we
can vary the reference pressure.
5.
ADF indicator: It is an ADF repetition instrument
placed in the navigation panel. It only has an indicative function, so any ADF
change has to be made in the navigation panel.
6.
Changing from the instrument panel to the navigation
panel: Clicking this area, the navigation instruments appear. When the arrow
passes over the area, it becomes a hand.
7.
Back-up lights: They tell us when each tank is below
the 10% of its capacity.
8.
Changing from the instrument panel to the radio panel:
Clicking this area the radio panel appears.
9.
Chronometer: Clicking the inner roulette we can vary
the time compression.
10.
Air speed: In km/h.
11.
Changing from the instrument panel to the engine
panel: Clicking this area we pass to the flight mechanism panel.
12.
Rpm indicator: Passing the mouse over them we will see
the rpm of each engine.
Pressing SHIFT+7 we can
eliminate the rudder wheel to improve the view of the instruments.
1. Radiator
temperature gauges: A reading from 0 to 100 centigrade degrees. During the
flight, the rear engines normally work at a temperature slightly higher than
the front ones.
2. Temperature/oil
pressure gauge.
3. Tachometer:
Rpm of the engines in pairs.
4. Mixture
control: Moving the mouse over the area of the right sign, we can vary all the
engines at the same time. Pushing over each of them we will do it individually.
5. Throttle
control: They work in the same way as the mixture control.
6. Changing
from the instrument panel to the engine panel: Clicking this area we will go
back to the instrument panel.
7. Changing
from the engine panel to the electric panel: Clicking this area the electric
panel will appear.
8. Changing
from the engine panel to the fuel panel: Clicking this area the fuel panel will
appear.
Like in the instrument panel,
moving the mouse over each one of the instruments, a sign with the right
indication will appear.
1.
Front tank fuel gauge:
2.
Central tank fuel gauge:
3.
Individual fuel tank keys: Of each one of the 12
engines.
4.
Rear tank fuel gauge:
5.
Main fuel tank key: It has four positions: VORDER (front tank), MITLERER (central tank), HINTERER (rear tank) and GESCHLOSSEN (closed).
6.
Changing from the engine panel to the fuel panel:
Clicking this area we will go back to the main instrument panel.
The rest of the panel
instruments related to the main instrument panel are totally functional.
Different from other FS aircrafts , a feeding cannot be selected from all the tanks
at a time. In case of doing it, the main key will be placed in the right
position according to the front tank.
Like in the instrument panel,
moving the mouse over each one of the instruments, a sign with the right
indication will appear.

2.
Outside lighting switch.
3.
Double DC indicator: It registers the existing voltage
and the consumed intensity in the dc

7.
Double battery indicator: It registers the voltage and the
intensity supplied by the battery.
8.
Alternator switches: There is one for each engine.
9.
Alternator state indicator: It registers the voltage
supplied by each alternator.
10.
Warning light of alternator failure: It turns on when
the alternator in question is not on line.
11.

4.
Open/shut button of the ATC panel.
5.
ADF Morse identification indicator: When working, we
will hear, in Morse code, the specific code of the ADF station selected on the
instrument panel.
6.
Main panel switch: It turns on/off the radio system.
7.

8.

selected frequency and a white small one, the decimals.
1.
Selected ADF frequency indicator.
2.
ADF direction indicator.
3.
ADF frequency selector.
4.
Automatic pilot: Follow the instructions in the DC3
flight manual. Important: The automatic pilot is unable to take the aircraft to
the fixed route. Therefore, it is necessary to fly in the appropriate
direction, and connect it after making both indicator readings coincide.
We hope you will enjoy the result of this project. This is
the product of many hours of hard work and dedication with
the only objective of making a dream come true: to feel as if we were
inside the cockpit of this mythical hydroplane. We have tried to reproduce it
with the greatest fidelity, finding instruments from those times, respecting
the magnitudes used by the German people (and, of course, their language),
simulating the inside of the virtual cockpit comparing it with photographs.
With best wishes from the DORNIER DO-X
development work team.
