Can't Get My Head Around VOR's.

Wed Dec 05, 2001 4:31 am

 Smile Hi everyone!  Smile

I have been playing on my flight sim, and have done some adventures.
It tells me to turn here and there, but it keeps telling me I must learn more about VOR's.
I've checked on help and all that, but I just can't get my head around them.
What do they do?
Where are they?
Thanks for any help!

VOR = VHF Omnidirectional Range beacon.

It's principle is based on timing. It's easy to understand if you know how the (VERY) early navaids worked.
Just imagine a lighthouse, with a beam of light that makes one turn in 36 seconds. Each time the beam is heading North, a red strobe on top of the lighthouse flashes. Now if you count the seconds from there, until the beam shines in your direction, and multiply it by 10, then you now your position relative to the lighthouse. For example if you counted 27 seconds, that means that someone standing at the lighthouse can see you when he looks to the West. It is said that your are on radial 270 of that VOR beacon, and your QDR=270. You are in the aircraft and of course you will have to look into the other direction to see the lighthouse, you'll be looking at the East, your QDM=90 (the Q-codes are not very often used anymore though).

A modern VOR works on the same principle, but instead of beams of light, radio transmissions are used, one fixed frequency (the one that you tune into) and a variable frequency that varies according to the direction of transmission.

Note that the info you get from a VOR DOESN'T say anything about the direction you're flying in (the heading of your aircraft). Only the POSITION of the aircraft. But when you're on radial 270 and your heading is 270 then you're flying away from the beacon, it is said that you're outbound and on your HSI, the "FROM" flag will display. But if you're heading is 90, then you're flying dead straigt to the beacon and a "TO" flag will display on your HSI.

Hope this helps.

Best regards,
GR.

Also, near VORs are where most mid-air collisions occurr.

You need to get yourself an IFR Enroute (Low Altitude) for the area you're interested in flying in. The VORs along with airways are identified in there. You can buy them at the pilots shop or for flight sim messing around ask any pilots for an old chart.

The following is a good web site that allows you to practice VORing around.

You will clue in with time. Took me like a year to figure out how to use VORs/NDBs in FS to navigate.

It took me about a year also, but now all that messing around in FS has payed off... I started real-world lessons and my instructor said I'm a natural untill I told him I played on FS and then he said oh, that explains it

Aerokid,

great explanation! I've been having trouble understanding VORs and that helped quite a bit. Saved your post to a .txt file. Anymore tips with VORs?

I picked up Rod Machidos books, they are excellent refrences for both sims and when you go for you PPL.
At worst, you screw up and die.

i am just a simmer aswell and im not bragging but it only took me a few days to understand VORs. I guess that because im a looser that sits on the computer all day long. i was flying just VFR for the first few days on flight unlimited and then i wondered what all those radios were for so i played a bit with them and reallised that they affected the HSI so i was wondering what the HSI did. then after about a week i reallised that the bar would centre evry now and then
so i turned the OBS knob and it sentered . And dont ask me how but thats when i realised that it showed me what radial i was on in relation to a point on the ground. Then when i went into the inflight map i turned on the VOR displays and noticed that i was on the radial that i though i was on so i was very proud of myself.
Just the other month my friends dad got his ppl so i gave him the game to use
he just flys VFR so i thaught him about navigation .
was very awsome to0 teach a pilot something!

For flightsimmers the more recent versions of MS Flight Sim have been lacking in good written help in the book. I remember in the olden days... back with Flightsim 1.0 and 4.0 actually had good pilots manuals that explained how VORs worked. I suggest that if you want to understand these things better head out to your local library and find the aviation books there, and check them all out.

Todd,

What I wrote is just the basic principle, I could go on about doppler VOR and VOR/DME if you're interested.

However, if you're looking for tips on how to navigate and calculate positions using multiple VOR's then you'd better ask the pilots on this forum 'cause I'm not really into that stuff. I have a few sims but don't have the time to play.

Best regards,
GR.

haha... I'm a CFII and still cant navigate from VOR to VOR in FS.... i was never able to figure out how to tune it up since i cant twist the knobs and select the radials like you do in the airplane.

well evrybody keep trying and ull eventually understand them i have a few tips for ppl that know how to use vors
if ur on right angles to the radial that ur hsi is on then point the HSI (or CDI wotever u cal it) a few degrees away from u that way ull have a better idea of when u are coming closer to the selected radial. then when it centres start turning and then select the proper radial and ull not have to make a really sharp turn
Any one with more tips please post them here
i love VOR Navigation its a challenge and requires more brains than someone who sits and stares at a GPS screen for the whole flight DERRRRR!!!!
