ered parachute wing should become too porous, more groundspeed may be needed to pressurize the wing, takeoff distance may increase, more RPM may be required to hold altitude, and fuel consumption may increase. 

At first sight, the suspension lines on the powered parachute wing might appear like an unorganized wad of strings. On the contrary, each line has a distinct purpose and each line has distinct properties. The sus - pension lines are sometimes designated A through D and differ between manufacturers; check your POH to know the line labels for your PPC. [Figure 3-12] The front suspension lines are located at the leading edge and the steering lines connect to the trailing edge. The

suspension lines come together at a point where they connect with the riser. (The risers are the connection between the suspension lines and the cart.) Many manufacturers color-code the wing suspension lines to assist the pilot in their preflight inspection and lay - out of the wing prior to inflation. [Figure 3-12] 

Suspension lines must be constructed of very strong materials, yet remain very small in profile to reduce parasite drag. The most commonly used materials are polyaramid and polyethelene, which are both carbon based. 

Kevlar ®  is a common polyaramid used for suspension lines. Its properties render it extremely strong, as well as resistant to stretching or shrinking, and it is not sus- ceptible to temperature changes. However, one criti - cal drawback of polyaramids is that they tend to kink or knot when looped around. When polyaramids are used to construct suspension lines, they are encased in a skin of a terylene product, like Dacron ®  or a product with similar properties. Polyethelene materials, such as Spectra ® , Dyneema ®  or Technora ® , are very strong as well as more flexible than polyaramids, which makes them more durable under hard use. However, polyethelene materials are more likely to stretch or shrink, and they are more susceptible to temperature changes. If your wing is equipped with polyethelene suspension lines, it is imperative you do not store your
