Help!! Excel Plog

[revilo_rehsif]

Hi all

Im looking at making a very basic excel plog. what i am making is a plog that when given aircraft heading and Tas as well as W/V. it will then calculate the groundspeed and track.

I am fine with the whole vectors idea, the problem lies in developing a formula that works for all situations.

Any help or suggestions will be much appreciated.

Kind regards
Revilo

Wouldn't it be better to calculate the heading given the track? After all, you are flying point to point, not just heading in one direction and seeing where you end up?

A quick Google search came up with this:
