Kolb Field PPG

• Ideal speed2–10 mph
• Upper limits≤ 12 mph base · gusts ≤ 15

Kolb Field PPG is a powered-paragliding (PPG) site on an open flat field in southeastern Pennsylvania (~295 ft MSL, Phoenixville/Kolb Aircraft area), not a ridge/thermal free-flight launch. The paraglidingEarth orientation hint lists 7 of 8 octants (N,NE,E,SE,SW,W,NW), which is the signature of an open field where pilots simply launch into whatever wind is present — direction is effectively omnidirectional, so the ideal and marginal arcs are set to the full 0-359 range. For PPG the real constraints are speed and gusts, not direction. Best conditions are light and smooth: calm to ~10 mph for the ideal window, with launches becoming difficult and risky above ~12 mph base and ~15 mph gusts (kiting/inflation and ground-handling failures dominate accidents in stronger or gusty air). Best time of day is the smooth-air windows around early morning (just after sunrise) and the evening "glass-off" before sunset, avoiding midday thermal turbulence in summer. Hazards: powerlines, trees and structures around field edges producing rotor/turbulence in stronger wind; standard PPG sites require pilots to avoid launching downwind of obstacles. No live weather station at the site (Windfinder forecast only); no published club/USHPA site guide with explicit wind numbers was found, so speed/gust figures are inferred from general PPG safety norms and the open-field orientation. Access/rating: appears to be a private/club PPG field — confirm permission and local rules with the operating group before flying. Note this is a paramotor (powered) site, so unpowered free-flight wind-window assumptions do not strictly apply.
