Understanding VOR

[@LuLeBe]

With all the details that pilots comment on here, i have to say that I really appreciate the technical side. Saw that the video is by R&S and immediately thought that they might finally explain not only what it does but also how it does it, and I want disappointed. Is anything, more theory about how the antenna does the phaseshift would be awesome!
Nevermind the navigation details, that's what aviation channels are for!

2:27 290 FROM is 110 TO, not 070.

[@pauldenisowski]

Good catch - yes, that's clearly a (verbal) "typo". Thanks!

@@pauldenisowski We obsessively pedantic people do come in handy sometimes. 😁

[@pauldenisowski]

@@johnopalko5223 Frankly, I'm happy people are watching these videos that closely :) The navaid and avionics related videos in this playlist were intended as an introduction for engineers involved in radio frequency test and measurement of navigational aids . There are *much* better videos available for people who are actually trying to become pilots. Thanks again!

I was scrolling down to see this comment

I was thinking the same thing John. But seeing as 290 from 360 is 70… I kinda (maybe) see where the error originated. Great vids all the same. 👍

[@jankeler4393]

Dispite the fact that this one is online for a good time now... I was wondering, if you might have swapped VAR and REF signal at 5:50. As far as I understand VOR the reference signal is modulated @f_0.

[@pauldenisowski]

Hi Jan - Actually, we're both right :) In a conventional VOR (CVOR), the VAR signal is the AM signal (at f0) and in a doppler VOR (DVOR), the VAR signal is the FM signal (f0 +/- 9.960 kHz). Since I didn't cover DVOR in this presentation, I used the VAR/REF assignments for conventional VOR. Thanks for pointing that out!

@@pauldenisowski Awesome!

[@ueberalleberge]

very good explained, especially that the second number behind the 3-letter code is the ICAO Chanel, I did not get this info clear on the IFR low enroute chart

[@delta69er]

The 3-number code is actually the DME channel number. Look at HDF in Riverside, CA. No 3-number code because it is just a VOR. I think it says it in the TPP as well but I can’t remember.

perfect, ty

[@liquidusblue]

Thanks for this. I can only fly VFR in Microlights but interesting to know how these work.

[@pauldenisowski]

Thanks for the feedback!

[@garryfelker6012]

At 3:41 in the video, there is an error. You cannot fly inbound with the OBS set to the radial you are on. Reverse sensing.

[@pauldenisowski]

Hi Garry - issues like reverse sensing are well beyond the scope of this video. :) The target audience is primarily non-pilots who work on navigational aids and who need a basic overview of navaids: absolutely not a substitute for proper pilot instruction (and I say that as an FAA-certified ground instructor).

[@johnopalko5223]

Yes, indeed. When you're tracking a radial, your OBS should be close to your compass heading, not 180 degrees away.

[@govinddwivedi3548]

Great explanation

[@shashankdahal345]

Thank sir

My friend is from Durham, small world :-)

[@uj6069]

Why does DVOR have 48 antennas?

[@NE-Explorer]

why doesnt the 180 radial result in destructive interference and thus no signal

[@MeaHeaR]

if the max frequency is 118mhz. why is Romeo bogota ubd Romeo cali bothê at 274 Mhz ¿¿¿

[@harveymanfrantinsingin7373]

Not to nitpick, as this is great information however.. At the 3-minute Mark you would have been better off quoting the 085 radial, as that is what's shown on the three examples of each planes VOR.
