PPG or PPC
What is the difference
Understanding
the Technology
There is much confusion about
the differences between a powered paraglider (PPG) and a
powered parachute (PPC). Even the FAA has so far failed to
come up with in a clear delineation between the two.
Why the confusion? Each aircraft category
has expanded into "hybrid" aircraft to include
features of the other. These hybrids have blurred the lines
that once separated PPG's and PPC's.
Why differentiate? For single place aircraft,
the FAA doesn't care if it's a picnic table attached to
a bed sheet as long as it's under 254 lbs and qualifies
as an ultralight. However, for two-place aircraft, the
FAA has decided that PPC's with be Sport Pilot and PPG's
will operate under a special FAA exemption.
The 3 main characteristics that currently
differenciate between PPG's and PPC's are:
• Wing Design
• Landing Gear
• Wing attachment

Gliding vs. Plowing
Some PPG pilots refer to PPC's
as airplows because a parachute has some much more drag
than a paraglider. Parachutes are far less efficient
and have much less roll response. While some prefer this
stability, with the introduction of eliptical wings,
somewhere between a paraglider and parachute, PPC hybrids
have moved closer to the efficiency and responsiveness
of PPG's.
Wheels make it easy
Launching a PPC is easier than
launching a PPG for two reasons... Parachutes are easier
to ground handle than paragliders, and launching in light
winds on wheels less work than a long hard run. Now,
the introduction of light weight wheel attachments for
PPG's has made launching easier for tandem operations,
pilots with physical limitations, and high altitude operations.
Attaching to the Wing
With heavier aircraft like PPC's,
the wing usually attaches to a solid tube or part of
the frame instead of the harness. However, some single-place
PPG's are attached to the wing by the frame, and some
of the largest PPC's have harness attachments directly
to the wing, and some of each use a combination. Using
wing attachment as a way to define an aircraft category
makes little sense, yet this appears to be the plan for
the FAA.
Freedom to Explore
The big advantage of PPG's over
PPC's is the ability to easily transport, set up, and
launch in a wide variety of locations, all over the country
and indeed all over the world. Transporting a PPC requires
a trailer and shipping it is usually cost prohibitive.
PPG require shorter take off runs requiring smaller launch
and landing fields. In the event of an engine failure,
PPG's can glide twice as far as a PPC, increasing opportunities
for safe cross country flights.
Learning PPC is easier
Yes learning to fly a PPC is easier
and less physically demanding. Though a wheel attachment
for a PPG does close the gap on this issue, the PPC is
far more stable and therefore much more like driving
than flying.
Which do you choose?
It depends on you, your location,
and what you'd like to accomplish with your flying. Watch
DVD's like Risk and Reward.
That's the best way to get to feel of powered paragliding
as compared to powered parachuting. The most important
thing is... if you've got that crocked gene that makes
you need to fly, get out there and do it!
