South Bend International to James M Cox Dayton International SBN → DAY
144 nautical miles (166 statute miles) southeast on a straight line, true course 138°, about 143° magnetic at the departure end (variation 5W). At 120 knots that is 47 min at the quickest height in today's winds (34,000 ft, a 64-knot tailwind), arriving about 12:25 am EDT (04:25 UTC), after sunset at the destination. Right now SBN is low IFR, wind calm; DAY is marginal VFR, wind from the west-northwest (290°) 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: 5 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.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the whole route.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from SBN.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- A320 at 34,000 ft, 29 nm northeast, 10:03 pm EDT (02:03 UTC): moderate chop turbulence. 106 nm along the route, 29 nm northeast of the line.

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 1 forecast point nearest it (FWA). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
