Question regarding the wind information on the navlog printout. For the various flight levels wind infomation is predicted in the following format for various weather stations:FL030: 154/22 (12.50) and up to FL390: 178/70 (-50.30).I assume the 12.50 is a tailwind and -50.30 represents headwind.Thanks,Ulysese BrownActiveSky Newbiex:-)

Hi,Welcome to ActiveSky!No, that's actually the SAT (temperature) in Celsius. The wind is displayed immediately after the flight level. Your first readout would mean winds out of 154 degrees (SSE) at 22 knots. And your second readout would mean winds out of 178 degrees (S) at 70 knots.Hope this helps!Edwin

Hi,What type of headwind and tailwind data are you seeking?Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg

There is no headwid/tailwind as such. Edwin.The bottom of the Navlog will show your average route wind speed and direction, you then need to assess your general route heading and work out, or guess your the head/tail wind component.The navlog also shows wind speed/direction at each waypoint so if you want you can calculate the head/tail wind component for each leg, personally I don't, I use the average value and apply it to my general route direction.Sorry for hi-jacking the post Jim.

Normally, when crossing eastbound there are tailwinds when crossing west the are headwinds causing higher fuel usage.
