Nav Computer: Centre dot on TAS (465 kts), rotate to put wind direction (300šT) on HEADING index and mark wind on centre line 80kts below centre dot (over 385 kts).

Rotate to put track 007šT next to HEADING index; read drift (10š right (Stbd)) and rotate to put track (007š) under drift (10šStbd).   Drift has now changed to 9šStbd so put track 007š under 9šStbd.   On heading 358šT the drift 9šStbd will give the required track, 007šT and the groundspeed is under wind mark: 428 kts.
