degreesXwind (modulo 90) times windspeed divided by IAS.
Given a wind speed of 30 knots which is 15 degrees off track (whether from behind or from infront) and an IAS of 90 knots you get a heading correction of 5 degrees (and the computer says you need 5). For a wind 30 deg off heading you need 10 degs and you get 10. For 60 degrees need 17 but it gives 20, and then at 75 if goes 20 which is right.
It is surprisingly its close to the correct heading correction all the way round and for speeds 60-120 knots. So this might be good for calculating the heading for an alternate say. I've never seen it before but I can't believe it isn't out there
