Myrtle Beach International to Altoona/Blair County MYR → AOO

398 nautical miles (458 statute miles) north on a straight line, true course 004°, about 013° magnetic at the departure end (variation 9W). At 120 knots that is 2 h 07 min at the quickest height in today's winds (34,000 ft, a 68-knot tailwind), arriving about 11:48 pm EDT (03:48 UTC), after sunset at the destination. Right now MYR is VFR, wind from the west-southwest (250°) at 9 knots, gusting to 14; AOO is low IFR, wind from the north-northeast (030°) at 5 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: 18 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 5 forecast points nearest it (FLO, RDU, RIC, EKN, PSB). 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.
