WHAT is a VOR? Explained by CAPTAIN JOE

dear friends and followers welcome back to my channel and lovely greetings from the otisburg vor close to Munich Airport today's video is very much addressed to my flight students as we'll be looking at the question what is a vor how does it work and what AV or has to do with a lighthouse the only tenant paid for this one so let's get started 36 county ground to write the write on Bravo and also to Victor today's video is brought to you by captain Jose fan shop stand out as an aviator in one of our great t-shirt designs click the link in the description box to get yours today happy shopping if you already know what a vor is etc and you want to learn how to determine your position relative to the vor there's another video coming out next week vor stands for VHF omnidirectional range I know I have made it any better VHF stands for very high frequency which makes a vor only a short range radio navigation system so in line of sight vo ours are only receivable from 25 nautical miles up to a hundred forty nautical miles usable radius and line-of-sight meaning if there's a mountain between you and the view are you will not receive a reliable signal even though you are within the station range omnidirectional comes from the Latin word Omni which means all or every direction meaning the vor sends out 360 lines let's call them lines for now which can be picked up by a vor receiver and in today's video we'll use a CDI a course deviation indicator with an OBS a only bearing selector which is very common in your standard Cessna Piper's etc now on your VFR or IFR chart this big ring with a symbol in the middle indicates a vor it comes in three different types now this one represents just a vor like the Southampton vor on the south coast of England this here is a view our DME so a vor with a distance measuring equipment showing you how far away you from the tuned in viewer like this will right behind me and last but not least you have the vo-tech and symbol taka and stands for tactical air navigation the most famous one in Germany is probably tango vor south of Stuttgart Airport next to the view our symbol you have this box now the top line States the name of the vor so the vor you see here in the background is otisburg south of Munich Airport below that is the vor frequency which can only range between 108 megahertz and a hundred and seventeen point nine five megahertz with 50 kilohertz spacing so otisburg would be one one two point three megahertz then you have the three-letter vor identifier OTT and next about the Morse code which is transmitted on the same frequency so for auto spoke vor it would sound like this now in the right hand corner of the box you sometimes see either a T & A or H these are different types of weather broadcasting facilities you can receive on the view our frequency this can be very helpful as the vor is receivable at greater distances than most atc frequencies that's why you often see the voice button or tuning knob on the radio navigation panel now depending on which app or chart you are using the presentation of the vor can vary a little for example for flight doesn't have the box next to the viewer but if you tap the station you get all the important information you need Jefferson uses different symbol on the approach and departure charts for example a little D in the left hand corner indicates a vor with DME so you see there are differences in presentation but any Apple chart comes with a legend which helps to clarify now a common question by the FAA our viewers aligned towards true north or magnetic north magnetic north as you can clearly see on the compass rose around the viewer if a vor would point towards true north it would always point in the same direction on the chart as and the charts are orientated towards true north but if you compare the hey Riverview are in northern Canada with a magnetic variation of 16 degrees and otisburg vor with three degrees you know vo ours are aligned towards magnetic north but actually the answer is both because some of the viewers in the far north of Canada are aligned with true north but that's a whole nother video right there okay let's take a look on how it actually works and I'll try to explain this as easy as possible now the principle is very similar to a lighthouse a lighthouse has a rotating light inside flashing a Morse code so the Sailor can write it down and determine his whereabouts now at the same time some lighthouses shine red and green colors warning the Sailor to not enter those areas due to cliffs or similar nature a vor works very much the same now picture two light bulbs one white shining in all directions and a red directional light rotating around the white light now once the red light passes through magnetic north the white light goes off for a second then you start a timer and wait until you see the red light passed by and stop the timer again now if you know the rotation speed of the red light let's say 60 seconds for 360 degrees and you've just timed 20 seconds that will mean 60 seconds equals 360 degrees 20 seconds are how many degrees 20 seconds times 360 degrees divided by 60 seconds equals a hundred and twenty degrees piece of cake does that make sense obviously AV rod doesn't emit any lights and you are not sitting there with a stopwatch but your vor receiver does that for you and projects that onto your CDI so in our example you are on a so called radial one to zero now what is a radial think of a vor as a navigational device that's ready dating 360 lines out of it so whenever your instructor or ATC guys says fly radial two to zero you immediately know you have to fly away from the station so say to yourself he wants me to fly radial two to zero of Kempton vor so I have to radiate away from it you can also think of it each radial to be an individual laser beam emitting a line on the ground away from the vor next up how do I read my CDI and what can it do for me now the CDI is a course deviation indicator and most common in smaller general aviation airplanes so let's take a closer look at this instrument to the left or the right of the instrument you have the OBS knob the so-called Omni bearing selector now this enables you to turn or dial the requested radial you're supposed to fly or determine your location relative to the vor by rotating the outer ring of the CDI more on that on the next video though in the middle you have the CDI the course deviation indicator better known as the needle which is hinged at the top of the instrument now think of the needle has an imaginary centerline on a highway or a radial you have to follow so if you were to be on the right side of the highway centerline your needle is to the left so if you move towards the left you approach the center of the highway the needle moves to the center of the instrument now you are tracking along a radial but if you continued left past the center the needle would move past the center and move towards the right side so you would have to correct to the right again does that make sense so in flight you navigate a radial by keeping the needle in the center and if it moves to one side you move towards it so remember fly towards the needle but there's a little more to it if you're for example fly towards the vor and the OBS is set up incorrectly and you get reverse sensing but more about that in the next video where I also will show you how to determine your position relative to the VR and how to intercept vor radials and other view are related maneuvers but sadly the error of the viewers is very slowly coming to and as the Global Positioning System GPS gets more more accurate for Android navigation and reliable enough even for approach procedures but the DFS did dodge a fluke see here on a kata German flight safety are spending a lot of money on maintaining and upgrading viewers so for example the vor in the background used to be called munich view our Mike uniform November but it was slightly outdated all the VR equipment and was recently updated to a more modern Doppler viewer and more importantly everyone is so dependent on GPS nowadays do you know who owns those 31 satellites if that country decides to flick the switch and shut it all down you better know how to navigate along a vor radial but more about that in the next video a big thank you to the DFS for allowing me to fly with my drone over your vor s I really really appreciate the contact with us and getting the permission for it thank you very much you guys that's it for today here's your checklist for today subscribe to the channel check activate the notification bell check follow my Instagram account check and don't forget a good pilot is
