Course deviation indicator

[VTJS17_Fire]

Hi folks,

 

I'm studying the navigation in the huey with VOR/ILS and NDBs. I read the manual and now, I'm stuck at the course deviation indicator.

 

There are two symbols on it: LOC and GS. What does this mean (see below)?

 

And is there a function in the huey, that I can read out, if the VOR is head-on or behind me (see picture)?

 

 

Thanks in advance,

Fire

I'm unsure if I understood your question well but,

 

Loc means Localizer, it gives you directional ( horizontal ) line of sight of for example an ILS

 

And GS is Glide Slope, giving you the typical 3° slope also for ILS approaches.

 

Basically, if you turn on the ILS system and set the correct frequency for an airport, you'll want to make your both needles ( GS and LOC ) form a perfect cross ( by flying your Huey around in the correct position )

 

That will mean you are correctly aiming at the field, and got the corresponding glide slope path to reach runway threshold. That is useful in very low visibility operations

LOC and GS ... localizer and glide slope?

:doh: Thanks.

 

Ok, but it there an indication, if the ILS is head-on or behind me (extrem low visibility).

Turn the helicopter in the indicated direction and then yaw left and right.

When the needle deflects in the opposite direction of the turn, you fly towards the station.

If it deflects in the same direction, you fly away from the station.
