Teller Airport to Dover Air Force Base TER → DOV
3,325 nautical miles (3,826 statute miles) east on a straight line, true course 070°, about 061° magnetic at the departure end (variation 9E). At 120 knots that is 20 h 31 min at the quickest height in today's winds (34,000 ft, a 42-knot tailwind), arriving about 11:14 pm EDT (03:14 UTC), after sunset at the destination. Right now TER is marginal VFR, wind from the east-southeast (110°) at 5 knots; DOV is low IFR, wind from the north (360°) at 12 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: 8 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
- SIGMET E22E: thunderstorms (a convective SIGMET) up to 40,000 ft, moving from the southwest at 20 knots, until 11:55 pm AKDT (07:55 UTC). Over the last 60 nm of the 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 TER.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
No pilot reports within 50 nautical miles of the line in the last three hours.

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 8 forecast points nearest it (OME, OTZ, AFM, BTT, FYU, ORT, JNU, ANN). 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.
