Limitations within the Simulator
Overview:
In the process of developing this highly sophisticated
simulation, it became apparent to us that many of the “Default Microsoft
Flight Simulator” functions are simply not effective for use when producing
a realistic simulation of a complex airliner. As such, we have developed
a simulation that to that largest degree possible does not use any default
Microsoft Flight Simulator functionality.
Systems that have been completely customized for realism and
functionality include:
Autopilot Functions
Engine Performance Model
Nearly All Mechanical Subsystems
Limiting our dependence upon Microsoft Flight Simulator has allowed us
to use this very popular simulation platform as a worldwide operating
environment without being severely limited by the original design of the
simulation. Occasionally however, this means that we had to accept
certain limitations on our simulation in order to accomplish our goals.
The vast majority of limitations we have found will never be experienced
by most users. A few should be kept in mind however, as they are
essential and important to the simulation:
Time Acceleration Limit:
Time Acceleration should be limited to 8x to ensure proper autopilot and
fuel system function. On some faster hardware machines, you may find
that the simulation will run faster than 8x, but we cannot guarantee the
accuracy of the computational process at speeds faster than 8x on all
hardware. (The mathematical iterations required for damping and control
law become prohibitive for most desktop machines when run at speeds at
greater than 8x, so we have not tuned the autopilot or fuel system for
operation at acceleration rates faster than 8x.)
Fueling Programs:
Do not use any non PMDG product to alter the aircraft.cfg file fuel section
entries.
Do not use any non PMDG product to alter the fuel load of the airplane.
Aircraft Loading Programs:
Do not use any non PMDG product to alter the loading of the airplane.
PMDG uses actual manufacturer data to model the Cl/Cd, moment
