Overview: In the process of modeling PMDG aircraft, we use a different
format than most developers in the implementation of the flight model.
Microsoft Flight Simulator assumes incorrectly that the “reference point”
from which the airplane is described is located at some point within the
airplane. When engineers design and build aircraft however, the
reference point used to describe the airplane and its various physical,
inertial and lift centric properties is located in front of the nose of the
airplane.
We make this decision because we are using actual mathematical models
for everything from the control laws of the autopilot system and
autothrottles, to the manner in which the lift/drag curve is modeled for the
simulation. This process allows PMDG to put a flight model/autopilot
control process in place that exceeds the capabilities and performance of
those that are based upon the center-of-rotation method used traditionally
in modeling MSFS airplanes.
There is a particular down-side to this affinity for accuracy, however.
Occasionally users write to us to explain that various commercial add-ons
or free add-ons to load anything from passengers to cargo to fuel do not
work correctly with their PMDG airplane. This is an unfortunate effect of
our modeling decisions and we are sorry for any inconvenience that it
might cause.
As will be discussed in various places in this manual, PMDG
recommends that you use only those tools that we have provided with this
package to interact with the loading of cargo, passengers and fuel into
this airplane. You can access fuel loading from the
PMDG/OPTIONS/FUEL menu, or from the PMDG LOAD MANAGER
application or from the FS ACTIONS SHORTCUTS menu in the MCDU.
Load Manager: The PMDG Load Manager is a comprehensive
application to allow you fine control over the loading of your PMDG MD-
11.
