Flight Modes
S10
Flight modes allow nearly all of the parameters (i.e. Dual
rates, camber adjust values, preset trims, all types of
mixing, etc.) to be programmed and then selected in flight
via a switch (es). The XP9303 offers up to 5 flight modes
that include Launch, Land, Cruise, Speed and Thermal.
Flight modes allow a sailplane’s programming to be
optimized for up to five tasks.
As an example, typically in launch mode:
• The flaps and flaperons are preset with positive
camber to give more lift.
• An elevator preset trim position that gives the best
climb is programmed.
• A high rudder rate with reduced exponential to give
authoritative steering control on launch is desired,
while the elevator and aileron rates are set to give
a medium response.
• Aileron-to-rudder mix is turned off, as are landing
flaps and elevator-to-flap mix while camber
adjustment of the side lever is programmed to give
proportional camber changes to allow for
last minute adjustments based on wind and
winch conditions.
• Aileron differential is set at 50%.
All these (and many more) programming parameters
can be selected by simply moving one switch. At the
top of the launch you prepare to zoom by switching to
the cruise mode. A single flip of the switch neutralizes
the trailing edge while giving the correct elevator trim
for cruise. Rudder-to-elevator and elevator-to-flap mixes
automatically turn on the programmed values and the
aileron differential is now at a much higher 75% for more
coordinated thermal turns. At the flip of a single switch
you’re ready for a zoom launch and for hunting thermals!
And remember there are 3 more flight modes available.
Once you start using flight modes, you’ll wonder how you
ever flew without them.
