Cape Cod Gateway Airport to Baltimore/Washington International Thurgood Marshall HYA → BWI
328 nautical miles (377 statute miles) southwest on a straight line, true course 245°, about 261° magnetic at the departure end (variation 16W). At 120 knots that is 2 h 41 min at the quickest height in today's winds (4,500 ft, a 2-knot tailwind), arriving about 10:59 am EDT (14:59 UTC). Right now HYA is low IFR, wind from the north-northeast (030°) at 12 knots, gusting to 19; BWI is marginal VFR, wind from the north-northwest (330°) at 6 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: 2 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 4 forecast points nearest it (ACK, BDL, JFK, ACY). A plus sign is a headwind, a minus sign a tailwind.

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.
