The base leg is the transitional part of the traffic pattern between the downwind leg and the final approach leg. Depending on the wind condition, it is established at a sufficient distance from the approach end of the land- ing runway to permit a gradual descent to the intended touchdown point. The ground track of the powered parachute while on the base leg should be perpendicu- lar to the extended centerline of the landing runway, 

although the longitudinal axis of the powered para- chute may not be aligned with the ground track when it is necessary to turn into the wind to counteract drift. While on the base leg, the pilot must ensure, before turning onto the final approach, that there is no danger of colliding with another aircraft that may already be on the final approach. 

The final approach leg is a descending flightpath start- ing from the completion of the base-to-final turn and extending to the point of touchdown. This is prob- ably the most important leg of the entire pattern, be- cause here the pilot’s judgment and procedures must be the sharpest to accurately control the airspeed and descent angle while approaching the intended touch- down point. 

As stipulated in 14 CFR part 91, section 91.113, air- craft while on final approach to land or while landing have the right-of-way over other aircraft in flight or operating on the surface. When two or more aircraft are approaching an airport for the purpose of landing, the aircraft at the lower altitude has the right-of-way. Pilots should not take advantage of this rule to cut in front of another aircraft that is on final approach to land, or to overtake that aircraft. 

The upwind leg is a course flown parallel and in the same direction to the landing runway. The upwind leg
