FSX Tweaks
We are not big fans of any modification to FSX, a good deal of our
support is caused by these changes. There is one tweak however that
is almost obligatory these days and that is the HighMemFix trick. This
change to the fsx.cfg file allows FSX to better handle texture address-
ing modes when using high levels of video memory. It also helps a lot
when memory is scarce and for products like the Airbus X A320/A321
(formally known as the Airbus X Extended) it is almost obligatory.
There are no negative effects reported. In our opinion, the HighMem-
Fix line should be added to everyone’s fsx.cfg file.
HighMemFix must be added manually to the fsx.cfg file as shown
below:

Note this tweak is not needed for P3D.
Flying the Twin Otter
Flying the Twin Otter is remarkably easy. The aircraft is stable, reliable
and even close to the ragged edge of the flight envelope will be
predictable. YouTube is full of videos of Twin Otters doing the most
amazing things. From landings in high winds to going vertical after
delivering a load of parachutists to their departure altitude. And you
should fly the Twin Otter like that. It can do things that almost no
other aircraft can do, so why not do it? Don’t spend too long on
knowing your exact Vr speed, the Twin Otter will most likely start to fly
before you reach it. Landing speed is so low that the Twin Otters are
regularly landed at far higher speeds to prevent other aircraft from
having to go around behind you.
There is just one thing you always need to keep an eye on. Turbo shaft
engines like the PT6A are highly reliable but the moment you stop
thinking about them they go wrong. You will need to keep an eye on
the engine instruments at all time and always use them with respect.
They combine low weight with a lot of power but they are complex
and small problems can spiral out of control in an amazing pace.
