Daily Overflights for Fairbanks, AK airspace.

Note: This page was updated for the last time on October 23rd. The flight data is no longer being updated. However, the flight archive is available.

Flight routes, altitudes and times (UTC) are shown and updated daily for the vicinity of Fairbanks for the previous day. Detailed flight information, derived atmospheric parameters at flight altitudes, and contrail formation forecasts are included in the table at the bottom. This infomation is updated at 18:00 Alaskan Standard (Daylight) Time. Last update: Monday October 23, 2006 17:56 AKDT.

Figure A: Latitude/Longitude chart showing the flight routes in the vicinity of Fairbanks and corresponding flight numbers. Black circles are centered around Fairbanks with radii of 10, 20, 50, and 100 km. Solid lines indicate overflights with forecasted contrail formation, dashed lines indicate overflights outside the contrail layer at the time of closest approach.

Figure B: Flight altitudes and times of passages are shown by dots. Light grey bars indicate the altitudes of contrail layers as forecasted from Fairbanks atmospheric sounding data using a standard contrail factor of 0.037 g/kgK. Dark gray bars represent a contrail factor of 0.0265 g/kgK. For flight times between available sounding data we interpolate the contrail layers linearly. The colors of the dots in Figure B correspond to flight numbers shown in Figure A. The time scale in the abscissa corresponds to hours UTC; the ordinate indicates altitude (m a.s.l.).

Flight Information Table: Flight characteristics with aircraft type, time (UTC), and position at the closest approach (Distance in km) to Fairbanks are included. Yes/No forecasts for contrail formation depend on the flight altitudes in reference to contrail layers derived from atmospheric soundings (grey bars in Figure B). Atmospheric temperature (ºC), dewpoint temperature (ºC), relative humidity (%), mixing ratio (g/kg), critical temperatures as threshold for contrail formation (ºC) are interpolated for flight altitudes/times between surrounding sounding levels and between sounding times.
