- At the 3 mins on the stop watch, place another mark at the bow of the target on the map.

- Grab the ruler tool and draw a line from one mark to the next.

- Take the measured number at the 2nd mark, and mulitply it by 2. This is your targets course.




Example:

I place a mark.

*TICK TICK TICK* for 3 mins. (since im impatient i up the TC and watch the needle on the chrnomoter whirl around the 120clock position 3 times)

I then place another mark.

I draw my line from mark to mark and it comes out to be 0.4 NM.
0.4 *2 is 0.8. My target speed is 8 kts.

this is great...i have used a other metod...but sam two dots and 2 min.... distanst x 60 /2 to get the speed. but how do I do this in metrik system.
