Yup, saw the avatar. I like it, and it's definitely relevant to the PF name and topic (which, according to Mr. Google, looks like Earth's gravity field anomalies), but I fear it's a little bit too detailed for such a low resolution profile picture, making the textual part of the image illegible...

gneill, so VAB is the effective velocity (speed) vector? Something like this? It's drawn in Inkscape, not some strictly math or physics oriented program, so expect minor inaccuracies. Assuming that I've followed your instructions properly ('tis all new to me, so sorry if I failed somewhere)...

Thank you for replying so fast! gneill, I understood the fact (well, somewhat I did) that the airplane has to deploy a part of its velocity to compensate for the wind's force. However, what bothered me was its calculation, what goes where? So ... the horizontal component should be, if the...

An introductory picture. Homework Statement Its number in my physics exercise book is 1.147. (just for reference, though completely unimportant). The actual problem description is written below. An airplane is flying from point A to the point B which is 400 km west from the point A...
