of items in view which the Flight Simulator display engine must try to
create. Go back down to ground level and the frames will be refreshed at
much higher rates, just as you need them to be during taxi.
Q. It’s quite jerky when near the terminal buildings or other built-up
areas. Why is this and what can I do to make everything run a little
smoother?
A. You can optimize your system from within the Flight Simulator
environment. By decreasing the demands made on the CPU and
graphics card you can increase simulator performance. By navigating
through the Flight Simulator Options/Settings/Display tabs you will find
several check-boxes and sliders that offer choices for display properties.
Remember that the more items you uncheck and sliders you move
towards the far left the less detail will be rendered for your simulator
session.
One major factor influencing simulator performance are scenery
PAGE 10
shadows. By unchecking scenery shadows in the Display tab you can
increase your performance by up to 25%. You will also notice that
unchecking the autogen feature significantly enhances the frame
refreshment rate (frames per second, or fps) in the densely built-up areas
of the airport.
It pays to experiment with these settings to find the configuration that
best suits your individual preferences. Further performance optimizing
suggestions can be found on page 2 of this manual.
Q. OK, I am at the gate and want to see the animated jetway docking
with my aircraft. It looks fine from one of the cockpit views but when
I go to the exterior views nothing happens. Why?
A. We have limited for performance reasons the viewing range of the
animation process to 500 feet. If you can’t see the jetway moving when
looking with an exterior view then you might have the viewing distance
set too far away, so to ensure you are comfortably in range to see the
animation try a setting of 400 feet.
Q. I am watching the jetway but it’s going crazy, jumping between
positions almost faster than the eye can see. What’s this?
A. We have experienced during testing that some add-on aircraft cause
this effect and seem to interfere with the jetway animation. We will
endeavour to refine the jetway animation process with each new airport
expansion pack release, but for now these anomalies are beyond our
control and we offer our apologies if it happens with your favourite
aircraft.
Q. The ground vehicles and airport staff are not really my kind of
thing and I would rather not have them there. Is there a way of
getting rid of them?
A. If you are at all familiar with the Windows ‘My Computer’ or ‘Explorer’
features then customizing your airport couldn’t be easier. Just navigate to
the Imagine Simulation folder found in the main ‘Flight Simulator/Scenery’
folder, locate the airport that you would like to alter and navigate into its
‘Scenery’ folder. Here you will see listed in plain language all the files that
are associated with the airport with filename extensions of BGL. If, for
example, you don’t want to see the cargo vehicles at the airport the next
time you start Flight Simulator then simply move the
‘vehicles_ground_01.bgl’ file to a location outside of the current folder.
Alternatively, if you would rather keep all the files in the same folder then
you could just rename the BGL portion of the file to something else and
Flight Simulator will ignore it next time you start.
But some words of caution - Imagine Simulation cannot be held
responsible for loss or damage that may result from moving or renaming
any files from the original installed locations. You manipulate these files
at your own risk.
Q. I have seen in the ‘Scenery’ folder some files that have the
extension ZZZ. I didn’t change these. What are they?
A. These files are installed ‘sleeping’. They contain large amounts of
objects that might cause average or low specification PC systems to

operate sluggishly when used with Flight Simulator. However, if you have
a new and up to the minute super machine then rename the ZZZ
extension to BGL and the next time you start Flight Simulator there will
be extra detail to see at your airport.
Q. When I’m on approach, about 12 to 15 miles out, my whole Flight
Simulator freezes. It only happens at this and other large airports.
What’s happening?
A. With airports created by Imagine Simulation and other major
developers there are literally thousands of objects that Flight Simulator
has to load and get ready to display once you get in range. If Flight
