Purdue University Airport to Capital Region International LAF → LAN
177 nautical miles (204 statute miles) northeast on a straight line, true course 036°, about 037° magnetic at the departure end (variation 1W). At 120 knots that is 1 h 32 min at the quickest height in today's winds (3,500 ft, a 5-knot headwind), arriving about 11:06 pm EDT (03:06 UTC), after sunset at the destination. 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: 4 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), from 8:00 pm EDT (00:00 UTC). Near the route, at the destination end.
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 LAF.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- A320 at 33,000 ft, 2 nm north, 8:36 pm EDT (00:36 UTC): moderate turbulence above 33,000 ft, remarks: zob. 138 nm along the route, 2 nm north of the line.

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 3 forecast points nearest it (IND, FWA, MKG). 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.

No temporary flight restriction on or near this route right now.
Daylight
Sunset at LAF 7:12 pm EDT (23:12 UTC), at LAN 7:01 pm EDT (23:01 UTC) (civil twilight ends 7:29 pm EDT (23:29 UTC)). At 120 knots the arrival at LAN is after sunset there (7:02 pm EDT (23:02 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.
