Go to your altitude menu and input your station pressure manually using the "SP" button and see what it tells you.
In other words make sure your zero altitude and your firing solution altitude are the same.
I just tried your suggestion, but nothing changed. In fact I changed the altitude to all sorts of absurd numbers trying to get a rise out of it - but nothing changed. I then started manually inputting each setting. When I came to Cant, I noticed it said 0.5 degrees.
When I changed it to "0" and clicked Done, my elevation then read "0".
Ya there is a error in input some where, I thought Twist rate but that looks right
It's always some little thing. Drove me batty! (It wasn't a long trip, either!)
Thanks for your help. Love this forum! And the podcast too.
