Aviation,Find wind direction and speed..?

Question

i have to find the wind direction and wind speed. the true course,varation,pressure alt.,temp,indicated airspeed, true airspeed,ground speed,wind correction angle, true heading,magnetic heading, and distance is all given. do i use my flight computer or a formula? which formula if any?

Answer 1

I pull up the wind page  on the FMS.

Answer 2

Yes use your flight computer (E6B)

Answer 3

The E6B is the best formula to use. However there are a few rule of thumbs you can research on the inernet.

TAS=  .02 % increase per 1000 ft. + IAS

Xwnd comp. = Sin < off runway * wind speed (KTS)

Hwind comp. = Cos < off runway * wind speed (KTS)

3 degree glide slope 5*GS = ft/min descent

Well I can remember any more right now.

This link will help a bit.
