AARRRGGHHHH NAV Computer
I was taught this yesterday and was happily calculating headings in order to get the track I want. I've gone back to it tonight and can't remember how to do it. Can anybody refresh my memory ?
1. I select the back of the computer
2. I line the dial onto the direction of wind (220 degrees)
3. I draw a line downwards to the extent of the wind (30 kts)
4. I move the card in the back to indicate TAS (100 kts)
5. I then select my required heading (170 degrees)
6. I look at the distance off track, (16 degrees)
I can then remember I need to have 2 things match up, the distance off track and something else.
When they both line up I read the heading off of the top of the computer and the speed which is read from the location off of the cross off of card vertical line.
From the above example I wrote down 184 degrees and 76 kt. If I set this again I can see that yes 184 degrees reads of 76kts but I can't remember the 2 things I need to line up. One of them is the degrees to the left or right of the end of the wind line, but I can't remember what the 2 things that must match up are.
Any help appreciated - I am really pulling my hair out in frustration. I had this all nailed yesterday.
As an extra bit of info, I remember it was itterative. I had to check distance of track, check it lined up, then move it over again, check the distance of track. I just can't remember what the 2 things I had to compare was
Please save my sanity!
