cone of confusion (plural cones of confusion) (aviation) A zone of indeterminism over a navigation beacon (such as a VOR), where the direction-finding ability of the receiver outputs a random direction as flying over the beacon results in no direction to the beacon, giving a spinning direction indicator display.
How do you find the distance between VOR radials? The distance from the station is computed by multiplying TAS or GS (in miles per minute) by the previously determined time in minutes. For example, if the aircraft is 7.5 minutes from station, flying at a TAS of 120 knots or 2 NM per minute, the distance from station is 15 NM (7.5 × 2 = 15).
Similarly, How many degrees is VOR cone of confusion? It is maximum around 30° and minimum at 90°. For 60° its about -20dB which is a ratio of 1/100th only. VOR cone of silence/confusion is where the signal is too small to be correctly interpreted by the VOR receiver, and you can see there is a strong signal fall around 50°-60° (that is 30°-40° from the VOR zenith)
What causes cone of confusion?
cone of confusion is the imaginary cone extending outward from each ear along the interaural axis and representing sound source locations producing the same interaural differences.
How big is the VOR cone of confusion?
Twelve miles up, the cone is wide enough to make any pilot’s compass spin like a merry-go-round while it tries to find north.
How do you find the distance from a station?
To find the distance between any two stations (except where station equations or equalities are involved) simply subtract the lower station from the higher one, ignoring the plus sign. You will get the answer in feet. On the Plan Sheets, the Station Numbers are usually written along the Survey Line.
How do you determine the time and distance from a VOR station? Divide the time it took (in seconds) by the number of degrees of change, and you get the time to the VOR: 120 seconds (2 minutes) / 10 = 12 Minutes to the VOR station.
How should the pilot make a VOR receiver check? How should the pilot make a VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface? Set the OBS on the designated radial. The CDI must center within plus or minus 4* of that radial with a FROM indication.
Does a VORTAC have DME?
A VORTAC is a facility consisting of two components, VOR and TACAN, which provides three individual services: VOR azimuth, TACAN azimuth and TACAN distance (DME) at one site.
What is VHF in aviation? The type of aircraft communications that most frequently comes to mind is that which takes place between Pilot and Controller, and uses a « Very High Frequency » (VHF).
What does VOR mean in aviation?
The Very High Frequency Omni-Directional Range (VOR) is a ground-based electronic system that provides azimuth information for high and low altitude routes and airport approaches.
What is ITD and ILD? The information embodied in interaural time differences (ITDs) and interaural level differences (ILDs) (a) allows listeners with normal hearing (NH) to locate sound sources on the horizontal plane, and (b) has a significant role in generating high levels of speech recognition in complex listening environments, for …
How is the cone of confusion resolved?
The cone of confusion may be partially resolved by rotating the head.
Why does cone of confusion exist in ground based navigation station?
As the aircraft moves closer to the VOR transmitting station, the VOR indicator needle becomes very sensitive and oscillates from side to side (i.e., the pointer acts in an unstable manner). The time an aircraft remains in the cone depends on its speed and altitude.
How often does a VOR ident? The frequency normally approved by the Federal Communications Commission is 108.0 MHz. Repair stations are not permitted to radiate the VOR test signal continuously; consequently, the owner or operator must make arrangements with the repair station to have the test signal transmitted.
How wide is a VOR radial?
VORs come with high, low, and terminal service volumes and dimensions. High-altitude VORs can be used up to 60,000 feet and 130 nautical miles wide. Low-altitude VORs service aircraft up to 18,000 feet and up to 40 nautical miles wide. Terminal VORs go up to 12,000 feet and 25 nautical miles.
What does VOR stands for?

How long is a station? 1 station is equal to 100 feet.
How do you measure the distance of a train?
Solution: Two trains means two distance formulas: DA = rA tA and DB = rB tB. Your first goal is to plug in any values you can determine from the problem. Since Train A travels 95 mph, rA = 95; similarly, rB = 110.
How do you find the equation of a station? A Station Equation can be written for point A: Sta 12+83 = Sta 26+45. This may be brought to the readers’ attention on a set of plans to ensure the appropriate station value be used for alignment calulations.
What minimum altitude is required to avoid the Livermore Airport?
both 2,100 feet and 3,000 feet MSL. (Refer to Figure 75) (Area 1) What minimum altitude is required to avoid the Livermore Airport (LVK) Class D airspace? 2,901 feet MSL.
How do you tune and identify a VOR? The only positive method of identifying a VOR is by its Morse Code identification or by the recorded automatic voice identification which is always indicated by use of the word “VOR” following the range’s name.
