I use the CR-3 (less pencil markings required than the E6B).
Your heading will be 084 and groundspeed 100.
Actually, when using the E6B, the reduction in forward speed due to larger angles of drift is allowed for (that's why the speed lines are curved).
For anything larger than 10 degrees of drift when using a Jepps unit, you will need to refer to the immediate left of the TAS triangle. Reference the angle of drift and read off reduced TAS due to drift. Head/tail wind is then applied as per normal.
Think of it as if you were holding 90 degrees of drift. Your forward speed to start with (forget headwind) would be zero.
ps, FTDK, next time you need an AFR, come see me. Amazing how many people have forgotten how to navigate once their GPS has spat the dummy, especially if it has happened during the flight.
