Sunday		 20:50:15 UPS958 757-200? northeast low Crossed EDH Blvd. at Serrano Pkwy, climbing through 12,000 feet. Aircraft type is unconfirmed, data block showed "7C44".

For each approach a captured image of the overall approach track is linked to contents of the Approach column. For approaches over EDH a captured image of the approach track at the point of maximum noise exposure is linked to values in the Crossing Altitude column. In almost all cases this is the point of crossing the western ridge of El Dorado Hills, whose at a point whose elevation is approximately 1,100 feet. Crossing altitudes are MSL (relative to mean sea level), as reported in the WebTrak traces of flight paths. The approach of greatest interest for EDH noise issues is the ILS (Instrument Landing System) approach. For ILS approaches the flight track image linked to the Approach column shows the aircraft at the IAF (Initial Approach Fix). For approaches not crossing EDH the time cited is for an approximate point of closest approach to El Dorado Hills.

Color code for highlighting in the log table:          Early morning approach
(between 3:30 a.m. and about 6 a.m.)
        Noise potential for EDH at ridge was "none":
