of the powered parachute’s inertia and weight. The
lift decreases rapidly as the powered parachute’s forward
speed is decreased, and the force on the landing
gear increases by the impact of touchdown. When the
descent stops, the lift will be zero, leaving the landing
gear alone to carry both the powered parachute’s
weight and inertia force. Any time you have a hard
landing, inspect your landing gear, tires, and structure
to make sure there is no structural damage.
Wing Blowing Over After Touchdown
When landing in a crosswind, there is a concern that
the wing will blow downwind during the after-landing
roll. This is due to the fact that the wing is flexibly
attached to the cart.
Anytime a powered parachute is rolling on the ground
in a crosswind condition, the upwind side of the parachute
is receiving a force that wants to push it downwind.
If no correction is applied, it is possible that the upwind
side of the parachute will rise sufficiently to cause the
downwind side of the parachute to strike the ground.
If the wind and/or the forward motion of the powered
parachute is great enough, a rollover may result. It is
important for a pilot to remember that the parachute
should be flown or pulled to the ground right after
landing the cart. The cart and the parachute’s movements
should be controlled together on the ground.

Night Operations and the
Powered Parachute
Flying a powered parachute after sunset requires a
private pilot powered parachute certificate. In addition,
the powered parachute needs to be equipped for
night operations by adding position lights for taxi and
flight. Position lights are green on the right, red on
the left, and white in the back. Anti-collision strobe
lights can also be used in addition to position lights.

the lines are not tangled (LOC). The takeoff area needs
adequate illumination to ensure hazards are avoided.
Typically, lights on poles can present a hazard at an
airfield.
A powered parachute flight where the preflight inspection
was completed during daylight, just prior to
sunset, and then the final landing made after sunset
may be a more feasible endeavor. If a powered parachute
pilot holding a private pilot certificate or higher
were to venture into night flight, Chapter 15 of the
Pilot’s Handbook of Aeronautical Knowledge should
be carefully reviewed to understand the parameters
that need to be considered prior to conducting a flight
in the dark.
Emergency Situations
This section contains information on dealing with unexpected
situations that may occur in flight. The key
to successful management of an emergency situation,
and/or preventing a problem from progressing into a
true emergency, is a thorough familiarity with, and adherence
to, the procedures developed by the powered
parachute (PPC) manufacturer. Hence, the following
guidelines are generic and are not meant to replace
the manufacturer’s recommended procedures. Rather,
they are meant to enhance your general knowledge
in the area of emergency operations. If any of the
guidance in this chapter conflicts in any way with the
manufacturer’s recommended procedures, the manufacturer’s
recommended procedures take precedence.
Review the lost procedures and flight diversion techniques
in Chapter 14 of the Pilot’s Handbook of Aeronautical
Knowledge. You must be able to select an
appropriate alternate airport or landing area and route,
determine there is sufficient fuel to fly to the alternate
airport or landing area, turn to and establish a course
to the select alternate destination, and maintain the
appropriate altitude and heading while doing so. As
a PPC pilot you must be able to select an appropriate
course of action if you become lost, including maintaining
an appropriate heading and climb if necessary,
Figure 12-1. Powered parachutes must be specifically
equipped for night flight.
The use of lighted runways for night flight imposes
several problems for the powered parachute pilot.
Setting up on a runway and conducting a preflight on
a powered parachute cart and wing in the dark could
tie up a designated runway area for a considerable
amount of time, not to mention raise issues about being
able to see the aircraft and wing components for
proper preflight inspection.
A pilot planning to fly a powered parachute at night
should ensure adequate illumination is provided for
takeoff. The wing needs to be illuminated to ensure
the wing cells are all open, the wing is centered, and
