On Nav Computer: to find TAS; in the AIRSPEED window put temperature (-35ºC) next to Mach No. Index go to MN (0.78) on the inner main scale and read TAS next to it on the outer main scale: 469 kts.  

On the other side put centre dot over TAS (469 kts), rotate to put wind direction (315ºT) under the HEADING index and mark wind speed 70 kts below centre dot (over 399 kts).   Rotate to put track (360ºT) under HEADING index and note drift is 7º Stbd (right).  

Rotate to put track (360ºT) under drift (7º Stbd).  

On a heading of 353ºT the drift is 6 Stbd, put the track (360ºT) under the 6 Stbd drift and note that on a heading of 354ºT the  6º Stbd drift gives the required track, 360ºT.  

Heading 354ºT, variation 10ºE, heading 344ºM.  

Ground speed, under the wind mark, is 418 kts and a distance of 600nm will be covered in 86 minutes.  

If the time at G is 1210 the ETA at B is 1336.
