Q: What is a Powered Parachute?
A: A Powered Parachute is a self-powered flying parachute with
a cart suspended from it, recognized by Transport Canada Aviation (TCA)
and classed as an "Ultralight" aircraft. The Powered
Parachute referred to as a PPC is relatively new to Canada and
considered to be the worlds easiest powered aircraft to fly and train
on; more importantly, it is a very safe way to enjoy the freedom of
flight.
Q: Do I need a Pilot's License?
A: Yes, (minimum requirements) You must pass a Ground school
course (provided by a PPC Flight Training Centre such as ours, aprox
10 to 12 hrs), complete a minimum of 5hrs of air-time 2 of those must
be solo (20 takeoffs and landings), and pass a written exam based on
Ultralight Rules and Regulations for TCA.
Q: How long does it take to complete the ground school course?
A: Individuals with no prior flight skills generally require
about 10 to 12 hours of ground school instruction completed within a 2
days period. Note: additional home study is required. Length of the
groundschool may vary between instructors. Transport Canada
specifies certain standards and approves material to be taught, but
not the time required. 10-12 hrs is felt by many to be adequate
to learn the material in their groundschools.
Q: What medical requirements are
necessary?
A: A category 4 medical (NO doctor necessary medical form
filled out).
Q: Why is the Powered Parachute so much easier to fly than an
airplane?
A: It is basically and inherently stable in flight and has only
2 flight controls to master: Left/Right steering operated by your
feet; and a throttle which controls climb, descent or level flight -
operated by one hand.
Q: What makes the Powered Parachute so stable in flight?
A: The pendulum effect of suspending the pilot cart below the
airfoil provides self-compensating stability. This requires no direct
input from the pilot. This inherent stability makes it extremely
difficult to stall, spin, loop or roll the aircraft, under normal
flying conditions.
Q: What is the wing (airfoil) made of?
A: The wing is a Ram-Air parachute that is made of ultraviolet
resistant ripstop nylon. This design was originally developed for
skydiving and was designed and constructed to withstand the high shock
loads occurring on openings from freefall speeds of 170 to 200 feet
per second. Thereby, it is "over-engineered" for its role as
a Powered Parachute; and with proper care should last ten to twenty
years.
Q: How do you get the Parachute Canopy inflated, on the ground?
A: Initially, the canopy is laid out on the ground inverted
directly behind the aircraft. At the start of the takeoff roll, the
forward motion of the aircraft forces air into the openings at the
leading edge of the canopy. This pressurizes the cells and the canopy
assumes its airfoil shape, which is necessary for flight. At this
stage, the airfoil provides lift and carries the aircraft into the
air.
The preparation and takeoff can be accomplished by yourself,
without assistance - a one-person operation, from takeoff to landing.
Q: How fast does It Fly?
A: Using a standard rectangular wing the Powered Parachute
flies at a constant 28 mph (45 kph) through the air (give or take a
couple). The ground speed is determined by the speed of the winds
relative to the flight direction. Newer shaped and elliptical wing
styles allow PPCs to fly faster, in the 30+ mph (50+ kph) range.
Q: What altitude is the Powered Parachute capable of climbing to?
A: Most Powered Parachute flights are conducted at 500 to
2,000' above ground level (AGL). Aviation regulations require a
minimum clearance of 1,000' (above the highest obstacle) over built-up
areas. Flights over 10,000' above sea level (ASL) have been made by
experienced pilots with this type of aircraft.
Q: How does the wind affect a Powered Parachute's flight?
A: Experienced Powered Parachute pilots are able to fly safely
in winds that do not exceed 24kph (15mph). At these speeds, even
though the wind speed is acceptable, gusting winds, may cause the
aircraft to exhibit some rocking motions as the airfoil attempts to
adjust to the varying wind speeds. As long as the gusts do not exceed
the maximum, this is not a problem for this type aircraft. The pilot
need not make corrections for the rocking motion, as the pendulum
effect is self-correcting. Needless to say, the aircraft should never
be flown in high winds, turbulence or other adverse weather
conditions. To coin an old flying phrase…there are old pilots and
there are bold pilots; but there are no old, bold pilots!
Q: What happens if the engine fails?
A: In the unlikely event of an engine failure, the only flight
characteristic change will simply be that you can no longer maintain
level flight, due to the loss of engine thrust. However, the aircraft
will continue to fly in a forward glide at its usual airspeed of
approximately 28 mph (45 kph). The descent rate, in the glide, should
be approximately 10 feet per second giving a 4 to 1 ratio (4' forward
for every 1' of descent). This, by way of comparison, is significantly
slower than the descent rate of a parachutist. Directional steering is
controlled via the canopy, hence, the pilot steers the aircraft the
same way, with or without engine power. The excellent glide ratio,
along with the maintenance of control, provides the Powered Parachute
pilot a greater range of suitable landing sites.
Q: How long can I fly on one tank of fuel?
A: Actual flight times will vary based on aircraft and
conditions; however, on average the engine consumes approximately 9-11
litres per hour (2 to 2 1/2 gallons). For example, a 45 litre (10
gallon) fuel tank usually allows 3 to 4 hours of flight. This
will allow a generous reserve of fuel.
Q: How do I transport and store my Powered Parachute?
A: The aircraft is easily transported on almost any trailer,
such as a snowmobile, flatbed, or even in the bed of a pickup truck.
If you have an enclosed trailer, that would be ideal. If not, a single
car garage will easily accommodate your aircraft; and, depending on
the garage, may even leave enough room for a small car
Q: How much room do I need to take-off safely?
A: Take-off distances can vary from 50 to 500 feet, Landings
even less, however, an area of 1200x1200 unobstructed is recommended,
this allows takeoff and landing directly into the wind and
incorporates a margin of safety.
Q: Can a Powered Parachute stall like a conventional aircraft? Are
stalls possible in any make of PPC?
A: Yes, any wing is capable of stalling regardless of type, Yet
under normal weather and flying conditions, with the proper knowledge
and skill, a stall is virtually impossible in a Powered Parachute. A
conventional aircraft's wings must have sufficient forward velocity to
maintain lift; hence, to fly. This dynamic is controlled through both
attitude (angle of attack of the wings) and throttle (engine power);
both controlled by the pilot. Get either of these out of sync, and the
aircraft wing will stall - generally, this causes the aircraft to spin
towards the earth. Takes all the fun out of it! Unlike an
airplane, the Powered Parachute is basically a constant speed vehicle
with an average airspeed of approximately 28 mph (45 kph).
Consequently, under normal flying conditions and with the proper
training it is virtually impossible to slow the airspeed sufficiently
to cause the Powered Parachute's airfoil to stall.
Q: What Weather conditions are PPCs capable of flying in Safely?
A: Our advice to all PPC pilots is to never knowingly take off
when conditions are beyond winds of 24kph (15 mph), and/or
inconsistent wind speed and direction. Heavy gusting winds are simply
not acceptable and are outside safe PPC flying parameters! No
exceptions should be made to this rule. Be assured that violent
weather conditions may induce a stalled wing - stalled wings do not
fly - regardless of the type of aircraft.
Information on the
Development of the Worlds first Powered Parachute, The ParaPlane

The development of the first mass-produced powered parachute took
approximately three years. As a aeronautical Engineer by the name of
Steve Snyder (god bless), was implementing and perfecting the use of
square ram-air parachutes, which had properties of a lifting wing. He
therefore assumed that if the person or payload suspended under the
chute had some thrust added, the distance traveled could be extended.
With more power, it could fly level or even climb. He then decided to
pursue this idea with the objective of creating a safe and simple
aircraft that even amateurs could fly easily.
With the help of Adrian Vandenberg, who had expertise in metalworking
and machining, he completed the first basic frame design in March of
1981. Daniel Thompson, a small engine expert, was brought on to the
project three months later to produce a powerplant. He fitted the
aircraft with two small Chrysler engines and the P-1 (prototype 1) was
born.
On the first day of test flying, attempts were made to get the
aircraft off the ground. Steve, at 150 lbs., tried easing the power to
full throttle at take-off, and managed to fly the craft to a height of
40 to 50 feet. He had a difficult time with control of the craft
because of the torque produced by both engines spinning their
propellers in the same direction. The total flight time was 30 - 35
seconds at a speed of 20 to 25 mph.
The P-1 flew more than 10 times, once by a woman weighing 110 lbs.,
which allowed for better performance of the test flights. Many
revisions were made during those test flights, including the addition
of a vertical stabilizer, flaps, ailerons, and optimizing the
parachute trim.
Ram air parachutes of the day had a flat profile and offered limited
control. More anhedral (downward curve) and ribs were added to the
chute ultimately giving the craft more stability and pressurization on
the P-1's parachute thus solving the control issue.
While the parachute control solutions were being worked out, Dan came
up with an improved airframe design, and with Steve's idea of folding
landing gear for portability, the P-2 was completed in January of
1983. The problem of torque was also solved by having the propellers
counter-rotating, thus canceling out each other's torque effect.
Three months later the P-3 made it's debut at the Sun & Fun
Airshow in Florida. Response was overwhelming, and the ParaPlane
Corporation was formed to produce the Worlds first portable, safe, and
easy to operate aircraft the P-3 had proven itself.
