Course to intercept method revised

[Hartmann]

Good work

I use the nomograph metod

i trace a line over his heading,and then i use the nomograph to estimate his speed.

after, is question of estimate how many kilometers runs in an hour of time,

finally i plot a course to the nearest point of his estimate heading keeping in mind the time that i need to reach this point, because the target is mooving too.

is useful do a hidrophone checks for detects the target
