There has been a recent spike in the number of operational event in the last six weeks involving VFR departures from KBFI to the west when in a south flow configuration. Four of the events were Pilot Deviations (PD)s, one of which also resulted in a Near Mid-air Collision (NMAC) being filed. Attached is the graphical depiction and textual description of the Vashon Departure. The KSEA Runways 16 final approach courses cross over the northwest corner of KBFI and, if aircraft do not fly the Vashon Departure correctly, they run the risk of being in close proximity of wake generating turbine powered aircraft.
