Chapter 2 - Aerodynamics of Flight
PPC Aerodynamics Summary
The following summarizes PPC aerodynamics:
• Increasing throttle causes the PPC to climb,
decreasing the throttle allows the PPC to
descend.
• The PPC flies at a relatively constant airspeed
and angle of attack in normal flying conditions.
• The weight of the PPC controls steady state
airspeed under similar conditions of wing size
and type, trim, steering line settings, and pilot
flare. Increased weight or load factor increases
speed and/or angle of attack.
• The lighter the weight, the slower the airspeed,
the less control pressure on the wing, and the
slower your descent.
• The heavier the cart (total weight under the
wing), the faster the airspeed, the more effort
required for maneuvers (foot steering pressure),
and the faster your descent.
• The wing set (rectangular or elliptical), size,
and cart weight have a strong influence on PPC
performance and maneuverability.
