Launching and Flying the Fusion
Before launching, hook in to the glider and do a careful hang check.
1. We recommend that you launch with the VG set between full loose and 1/3 on.
If you launch with the VG set partly on, you must make sure that there is no way that the
excess VG rope can catch on anything on the ground or that you can step on it. One way
to do this is to fold the rope into a flat loop about eight inches long, and tuck it around
the outside of the right downtube above the bottom front, rear, and side wires.
If the wind is more than 10 m.p.h. or gusty you should have an assistant on your nose wires on
launch, and, if necessary, an assistant on one or both side wires. Make sure all signals are clearly
understood. The angle at which you hold the glider should depend on the wind speed and slope of
the terrain at launch; you want to achieve a slight positive angle of attack at the start of your run.
2. Run aggressively on launch and ease the bar out for lift off.
3. The flying characteristics of the Fusion are typical of a high performance flex wing. Make your
first flights from a familiar site in mellow conditions to give you time to become accustomed to the
glider.
4. We recommend that you hang as close as possible to the basetube in the glider - this will give you
lighter control pressures and better control.
Minimum controllable airspeed and minimum sink airspeed
There are two important airspeeds with which all hang glider pilots should be intimately familiar;
minimum sink airspeed (hereinafter referred to as MSA) and minimum controllable airspeed (MCA).
The most important of these two is MCA . Minimum sink airspeed is that speed at which your descent
rate is the slowest possible. It is the speed to fly when you want to maximize your climb rate in lift, or
slow your rate of descent to a minimum in non lifting air. (You would normally not fly at MSA in
sinking air; the strategy there is normally to speed up and fly quickly out of the sink. By minimizing
your time spent in the sinking air you minimize altitude lost, even though you have momentarily
increased your sink rate by speeding up.)
Minimum controllable airspeed is that speed below which you begin to rapidly lose effective lateral
control of the glider. Recognition of this speed and its implications is a more subtle problem than many
pilots realize. We have seen several instances of pilots who were having a lot of trouble flying their
gliders simply because they were unknowingly trying to fly them too slowly; below the speed at which
the glider responded effectively to lateral control inputs. It is our opinion that a great percentage of
hang gliding accidents are caused by inadvertent flight below MCA, and subsequent loss of control of
the glider with impact preceding recovery. Such incidents are usually attributed to “stalls,” but it is not
the stall per se that causes the problem, indeed the glider need not even be “stalled” in the traditional
sense.
There is no necessary cause and effect relationship between minimum sink speed and minimum control-
lable airspeed. MSA is determined primarily by the wing loading and span loading, the wing planform,
