Chapter 3 — Components and Systems
Center of Gravity Adjustments
Each manufacturer has specific procedures in the
Pilot’s Operating Handbook (POH) to adjust the CG
of the cart, so that the cart is hanging at the proper
nose high/nose low position—including the weight
position in the cart and the fore/aft position of the
wing attachment points.
As discussed in Chapter 2, the attachment points for
the wing (parachute) must be adjusted for variations
in pilot weight, which affect the center of gravity (CG)
location of the cart.
There are typically two types of wing attachment systems:
center of gravity adjustment tubes, or a bracket
with a number of fore and aft attachment points. Each
of these systems performs the same task. Either system
adjusts the wing attachment points based on the
cart CG. This is primarily based on the weight of the
occupant in the front seat, usually the pilot. The rear
seat occupant’s weight does not typically come into
consideration when determining the CG position of
the PPC, as the rear seat is usually positioned very
near the cart CG. To maintain the best overall performance,
the aircraft needs to fly with a slight noseup
attitude, as specified in the aircraft POH.
Use the POH to determine the proper adjustment for
the particular aircraft because there are many configurations and designs that vary by manufacturer, make,
and model.
