Trenton Mercer Airport to Harrisburg International TTN → MDT

89 nautical miles (103 statute miles) west on a straight line, true course 267°, about 279° magnetic at the departure end (variation 12W). At 120 knots that is 45 min at the quickest height in today's winds (4,500 ft, a 2-knot headwind), arriving about 12:24 pm EDT (16:24 UTC). Right now TTN is marginal VFR, wind from the north (360°) at 11 knots, gusting to 21; MDT is marginal VFR, wind from the west-northwest (290°) at 9 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 return flight

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). Near the route, at the departure end.
  • AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 40,000 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 TTN.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

  • B738 at 36,000 ft, 23 nm south, 8:54 am EDT (12:54 UTC): moderate turbulence. 40 nm along the route, 23 nm south of the line.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
