Source for Winds Aloft Information on FltPlan.com

Forecast winds data is available up to 36 hours in advance. From 36 to 72 hours in advance, we'll give you the winds at 36 hours. For domestic flights more than 72 hours in advance, we use historical winds aloft data for that date. For international flights, we use the closest matching winds forecast to the time of your flight. As a note, any time you display the Navigation Log (NavLog) , FltPlan.com gives you the most current winds data available based on the criteria listed above.


Winds Aloft information can be found on the NavLog, and expanded winds aloft information can be viewed in our 'Winds Aloft' Matrix by clicking the "Winds Aloft" button at the top of your NavLog, and on our Weather Page.  When you check the Winds Aloft Matrix, you'll find that it is set up for 'Fix' (left-hand column) and 'Altitudes' (across the top).


You'll get the following information within each matrix box:

1) Wind direction and speed. ( i.e. 270/30, which would mean the winds are from 270 degrees at 30 knots)
2) International Standard Atmosphere (ISA)  temperature is the deviation from standard temperature at this altitude and fix. i.e. +3 means the temperature is 3 warmer than standard, -8 means the temperature is 8 degrees less than standard. The number in brackets next to ISA is the standard temperature at the associated altitude.
3) Comp is the Wind Component. + means tailwind and - means headwind. (i.e. + 24 means a 24 knot tailwind)

  • On the NavLog, four different altitudes are displayed.
  • On our Winds Aloft Matrix you can get up to 10 different altitudes of winds for along your route of flight.
