Target speed estimation

Open your stopwatch
Mark the current position of a contact as close as you can
Start the stopwatch, after 3 minutes and 15 seconds...
Mark the current position of the contact as close as you can
Measure the distance between the two marks. Divide by 100 to get the speed in knots.

So if the distance was 800m they are traveling 8kts. If it was 1100m they are traveling 11kts

Step 1 & 2 & 3:

Step 4:

Step 5:

For Imperial users (huh??) only measure for 3 minutes.
