On Nav Computer: to find TAS; in the AIRSPEED window put temperature (-55ºC) next to Mach No. Index go to MN (0.84) on the inner main scale and read TAS next to it on the outer main scale: 483 kts.  

On the other side put centre dot over TAS (483 kts), rotate to put wind direction (020ºT) under the HEADING index and mark wind speed 60 kts below centre dot (over 423 kts).  

Rotate to put track (070ºT) under HEADING index and note drift is 6º Stbd (right).  

Rotate to put track (070ºT) under drift (6º Stbd).  

Note that on a heading of 064ºT the  6º Stbd drift gives the required track, 070ºT.   Heading 064ºT, variation 11ºW, heading 075ºM.  

Ground speed, under the wind mark, is 441 kts and a distance of 495nm will be covered in 67 minutes.  

If the time at L is 1355 the ETA at M is 1502.
