How wide is a VOR Radial on either side of the center line ?

Question

I mean how much wide does it get as go further and further away from the station.........??

Answer 1

At 10 nautical miles from the station the beam is about 1,000 feet wide (500 feet either side of center). At 60 nm from the VOR a 1 degree beam is 1 nautical mile wide (1/2 mile either side of center). At 120 miles from the station, the beam is 2 nm wide, etc. VOR signals are usually accurate within .4% error and the max allowable error is 1.4%. The beam widths quoted are for altitudes below 15,000 feet.

Answer 2

To infinity and beyond. If you are talking about angles then they go unlimited. Refer to above poster for width and distance from the station. Airways are 4nm wide on either side which are comprised of VOR radials, and you are expected to fly in the middle of it.

I havent flown a VOR airway in 7 years, I fly them with GPS which usually keeps me within a few hundred feet of the centerline.

Answer 3

VOR radials don't really have width.

If you are say, on the 90 degree radial, then if you move to either side you could be on the 90.1 radial, 90.2, etc. or the 89.9, 89.8, 89.7 ect. radial.

Vector airways, however, are controlled airspace and have a width of 8 miles (I think thats right...)

Answer 4

A radial has no appreciable width.

A 1º span is a mile wide at about 57.3 miles from the station.

Aviation charts show the radial to the nearest whole degree.  The radial (to a hundredth of a degree) can sometimes be found online in the book of "Location Identifiers."
