Landing the Fusion
We recommend using an aircraft landing approach (45 entry leg, downwind leg, base leg, and final leg)
whenever possible, and we suggest that you practice making your approaches with as much precision
as possible. Under ideal conditions, landing approaches are best done so as to include a long straight
final into the wind at a speed above best L/D speed. In a very limited field, or a field which slopes
slightly downhill, when landing in light wind, you may need to make your final approach at a slower
speed, perhaps as slow as minimum sink, in order to be able to land within the field. In winds of less
than 5 mph, if the slope is steeper than 12:1, you should seriously consider landing downwind, uphill;
or crosswind, across the slope. Landing attempts which require slow speed approaches, maneuvering
around obstacles or into a restricted area, or downwind or crosswind landings are not recommended
for pilots below an advanced skill level.

Making your approach VG full loose to VG 1/3 will also increase the glider’s roll sensitivity, and some
pilots have had difficulty with roll yaw oscillations on final. The best way to avoid this is to fly your
entire approach at a constant airspeed, and to control your touchdown point by making adjustments to
the shape of your pattern. In particular, we recommend against the technique of make a diving turn
onto final. This maneuver, sometimes called a “slipping turn” is often taught to student hang glider
pilots as a way to lose altitude during the approach. While it will work reasonably well with low or
medium performance low aspect ratio gliders which have high levels of yaw stability and damping, and
which are able to lose energy by diving because of the large increase in drag at higher speeds, on a high
performance glider this technique serves only to convert the energy of altitude to energy of speed, while
at the same time suddenly increasing the glider’s sensitivity to control inputs. The result is a high
probability of overshooting the intended landing point and the prospect of roll / yaw oscillations which
may interfere with a proper landing. If you develop good habits and the skills to fly precise approaches
now, it will make your transition to higher performance gliders easier later on.
Once established on a straight final approach, with wings level and flying directly into the wind, you
should fly the glider down to where the basetube is between three and six feet off the ground. At this
altitude, let the control bar out just enough “round out” so that your descent is arrested and your flight
path parallels the ground. The remainder of your approach will consist of bleeding off excess speed
while paralleling the ground and keeping the wings level and the nose into the wind until it is time to
“flare” for landing.
