Rocky Mountain Metro Airport to Jack Northrop Fld/Hawthorne Municipal BJC → HHR

728 nautical miles (838 statute miles) southwest on a straight line, true course 245°, about 236° magnetic at the departure end (variation 9E). At 120 knots that is 7 h 30 min at the quickest height in today's winds (8,500 ft, a 23-knot headwind), arriving about 9:09 am PDT (16:09 UTC). For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 1 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
