Well I passed with 97% or something similar, only 1 question wrong in the exam, it is good yes.
The radial questions can be a bit of a nightmare, I guess it’s all about visualization, it’s best to draw it on a piece of paper.
Just think of the VOR, and the radials emanate out from the centre, so the 000 or 360 radial will go (magnetic) North, and the 180 radial goes South (obviously), so let’s say you are to the North East and heading South West “To” the beacon, if you rotate your OBS on the HSI you will get the CDI needle to read 2 things when centred, it will read 045 degrees “FROM” and 225 degrees “TO”, so because you are heading “TO” the beacon (we know this because of our direction) then it fits that we are tracking the 225 radial, but the truth is that we are really tracking the 045 Radial in the reciprocal direction, if we are heading away from the beacon in the NE again then they will still read the exact same way, so from this you can ascertain your position.
If you don’t know where you are in relation to the beacon you can tune and ident a VOR, then rotate the OBS to get a “FROM” reading, this will show you what radial you are on, so a 110 “FROM” reading shows you are just East South East of the beacon etc etc.
You can basically do the same thing to determine your position from a particular radial.
I also have the BGS feedback papers as well 🙂
