Well I get the compass perfectly, it's just the RMI thing.. This RMI is really doing my head in, I still don't get it. This is how I see it: I see three aircraft's. they all look exactly the same but it's just that they're on different positions on the grid. the red needle is pointing to the west. I just can't figure it out for some reason, does the fact that the aircraft's are on different position on the grid make any difference? number 3 is directly above the beacon. while 1 and 2 are far apart. and shouldn't we look at the Artificial horizon? how do I know which aircraft it is by just looking at the artificial horizon? I think it's better to do the exclusion method, like if we know the compass (which is easiest to find) then we can exclude some options etc. how do we know the artificial horizon? since the RMI is just not ticking...
