Navigation refresher

[Raven_Morpheus]

Hello

 

I plan on doing some basic empty map flying in the Huey to practice navigation and landing.

 

What I plan on doing is taking off from Batumi and landing at Kobuleti.

 

I'm my mind I've got this procedure prior to take off -

 

1. Check available info for tower and ILS frequencies.

2. Set ADF to tower frequency.

3. Set ILS/VOR to ILS frequency.

 

 

I've checked Lino Germany's Excel spreadsheet for frequencies and I can see that there are the following frequencies that I could use for Kobuleti -

 

ILS Outer - 870.00

ILS Inner - 490.00

ILS - 111.50

Tower - 133.00

 

 

So, to navigate from Batumi to Kobuleti I would do the following before take off -

 

1. Set the ADF dial to 133.00, because that's the tower fequency listed.

2. Set the dial on the ILS/VOR panel to 111.50, because that's the frequency listed for ILS.

 

Correct?

The 133.00 MHz tower frequency is in the VHF band.

 

The ADF works off NDB beacons in the kHz range, so that one won't detect the tower transmissions. The NDBs and their frequencies are in the map, and are tuned separately in the aircraft.

 

The UHF comes with a direction finding mode allowing for direction finding of transmitters on the UHF band. Those would be the 200+ MHz frequencies. Not sure if this is implemented.

 

You also have the FM radio with homing capability - check the manual.

 

Been a long time since I messed with this, so I'll leave it to someone else to sort out the details.

Thanks.

 

I'm always confused when it comes to how to navigate via instruments after I've not done it for a while, not that I've ever learnt to do it properly, yet. I need to establish a procedure and write it down so that I can refer back to it when I need to (although I'm sure I've asked this before but never actually established a procedure to refer to).

 

The NDB for Kobuleti is, according to Lino Germany's map, 870 (it's combined with the ILS outer marker, and there is also one for the ILS inner marker set to 490).

 

So I just tried that, set the ADF dial to what I think is 870, it only has 850 to 900 with a mid point between the two which I presume would be 875! Oh for a digital readout...

 

Anyhoo after setting the ADF dial to 870 the compass was pointing at a bearing of about 60-65 degrees, which when looking at the F10 map seemed about right for Kobuleti based on my starting position and bearing.

 

As far as I recall the FM radio set is only for navigating to beacons laid down by troops, such as in the Stray Eagle mission where the guy tells you he's on [whatever frequency it is] and you can then set the FM radio to that frequency, it then gives you a homing tone and changes the position of the lines on the Course Deviation Indicator, which you then realign so that when you're headed in the right direction/height (vertical line is direction, horizontal line is height?) they cross in the middle?

 

 

So this is the procedure I've got now (also after watching a VOR/ILS tutorial vid by jojo the circus boy) -

 

From start up of the helicopter (or whilst in the air) -

 

1. Set ADF to the NDB frequency of the place I'm going to (which for Kobuleti appears to be either 870 or 490).

2. Set Nav-Comm to the runway frequency, which for Kobuleti is runway 07 at 111.50 according to the info on the kneeboard and is the ILS frequency I noted earlier from the spreadsheet.

3. Turn the outer dial on the Course Deviation Indicator (the instrument below the compass) so that it matches the direction of the runway, which in the case of Kobuleti is listed as 064 degrees on the kneeboard, although Lino Germany's map has it as 70 degrees?.

4. Switch the sensing volume switch to High. (on the right of the CDI)

5. Turn the dial for the volume up if I want to. (below the switch in step 4).

6. Make sure I've turned the Nav-Comm on and that the dial furthest from me on the ADF panel is set to ADF.

 

EDIT - yep, that procedure works. I just managed to navigate to Kobuleti from Batumi just fine, well if you count not seeing the airport until I got the bleeping noise telling me I was there and noticed the lines on the CDI moving into place. The compass led me a little to the left of the airport (over the lake that's there) so I couldn't see it...

I made a video covering all the nav systems in the huey. This should help.

That's a great video, thanks a lot! :thumbup:
