Gerald R Ford International to John Glenn Columbus International GRR → CMH
210 nautical miles (241 statute miles) southeast on a straight line, true course 145°, about 151° magnetic at the departure end (variation 6W). At 120 knots that is 1 h 08 min at the quickest height in today's winds (34,000 ft, a 65-knot tailwind), arriving about 3:10 am EDT (07:10 UTC), after sunset at the destination. Right now GRR is marginal VFR, wind from the south-southeast (160°) at 4 knots; CMH is marginal VFR, wind from the north-northwest (330°) at 8 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: 6 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 GRR.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B738 at 1,800 ft, 19 nm northeast, 1:18 am EDT (05:18 UTC): overcast from 1,800 ft to 2,700 ft, remarks: during the climb. 110 nm along the route, 19 nm northeast of the line.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 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 3 forecast points nearest it (MKG, FWA, CMH). 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.

Daylight
Sunset at GRR 7:04 pm EDT (23:04 UTC), at CMH 6:56 pm EDT (22:56 UTC) (civil twilight ends 7:24 pm EDT (23:24 UTC)). At 120 knots the arrival at CMH is before sunrise there (7:38 am EDT (11:38 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
