Hi,I could not find any forum for my question - I'll try here.Its most probably quite simple but anyway :I am looking for a formula to calculate the windcomponent for my flight planning project, I found a formula through Google but this will not work.Windspeed X cos( winddirection - track ) will produce funny results . . .Any ideas ?Karl from sunny ( and hot ) Berlin

Check http://www.navfltsm.addr.com/nav-downloads.htm for a "Virtual E6B" application that will do the calcs for you.

That's a great site, lots of good info and practice. I think if I was managing a VA I would want my pilots to complete that course and exercises prior to flying something with an FMC and all the electronic help that glass provides. Won't cost the $8,000 or thereabouts that my IR cost me, but it is at least an introduction to the basics that every pilot should know when they're flying in the simulated instrument system :)Bruce.

Just in case somebody is interested :The formula for windcomponent for winds aloft is:WC = Windcomponent = -68WS = Windspeed i.e. 75 ktsWD = Winddirection i.e. 300TR = Track or heading i.e. 275WC = WS X Cos((WD-180)-TR)X (PI/180)Karl,Berlin
