VOR and reverse sensing

"Jeffrey Voight" wrote in message ...

When you see 'TO' think 'THROUGH'. That is, the 300 radial points all
the way 'THROUGH' the VOR. So, if you are on the 300 radial, CDI says
'TO (THROUGH)', you will fly 'THROUGH' the VOR station on a heading of 300.

The "radial" does not go through the VOR. The OBS doesn't require you to be on the
radial you have it set to however. Once you fly to the VOR on a given radial the
TO/FROM indictaor will flip as you start flying out the reciprocal radial.

When you see 'FROM' think, where is that signal coming 'FROM'? That is,
if I spin the dial on the CDI and it centers on 120 and FROM, that
signal is coming 'FROM' the VOR on a heading of 120.

Better, why don't you use this for TO as well? The operative word here
is that is where the signal is with respect to the VOR station NOT the
aircraft.


The other thing he told me was that the only time I should see 'TO' is
when I'm trying to get 'TO' the VOR. The only time I should see 'FROM'
is when I'm trying to verify where I am (location fix).

Nonsense. You want the FROM indication when you are headed away from
the VOR, otherwise you will have reverse sensing.

The general rule is that you want to set the OBS to approxiately the same direction
you want to be headed. If you want to fly inbound on the 220 degree radial, you need
to set the reciprocal (40 degree) on the VOR because that is the direction you want
to be headed.

You need to crack the books a bit more.
