Baltimore/Washington International Thurgood Marshall to James M Cox Dayton International BWI → DAY
352 nautical miles (405 statute miles) west on a straight line, true course 280°, about 291° magnetic at the departure end (variation 11W). At 120 knots that is 2 h 57 min at the quickest height in today's winds (12,500 ft, a 1-knot headwind), arriving about 11:43 pm EDT (03:43 UTC), after sunset at the destination. Right now BWI is IFR, wind from the northeast (040°) at 8 knots; DAY is IFR, wind from the northwest (320°) at 7 knots. 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: 3 flights in the DOT's last twelve reported months, the route's page.

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 3 forecast points nearest it (RIC, EKN, CMH). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
