Tweed/New Haven Airport to Morristown Municipal HVN → MMU
75 nautical miles (86 statute miles) west on a straight line, true course 249°, about 262° magnetic at the departure end (variation 13W). At 120 knots that is 36 min at the quickest height in today's winds (4,500 ft, a 5-knot tailwind), arriving about 9:46 am EDT (13:46 UTC). Right now HVN is marginal VFR, wind from the north (360°) at 9 knots; MMU is marginal VFR, wind from the north-northeast (020°) at 6 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: 1 flights in the DOT's last twelve reported months, the route's page.
The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words
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.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 33,000 ft. 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 HVN.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- urgent SF50 descending, 0 nm south, 6:50 am EDT (10:50 UTC): light turbulence, overcast above 1,200 ft, remarks: during the descent runway 5. At the destination end, 0 nm south of the line.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
