Talking Scalloping

This is one of those "out of interest" ones. While I do understand what scalloping means in terms of VOR's, I'd like to know why is it called "scalloping"?

I had to pull my English-Finnish dictionary and found out that a scallop is one of those marine thingys that you can eat in a fine restaurant and get a a huge bill and a nasty stomach ache How did they come up with that word for VOR error?

Default Scalloping

Hi kkyle,
As you say a scallop is a shellfish with two fan-shaped shells (the same as you get on the shell petrol sign!). The alternative dictionary definition says "one of a series of small curves along an edge" - again the same as the shell petrol sign. When you get scalloping on a VOR the aircraft will fly a series of curves (rather like a snake) as opposed to a constant heading as you would have expected. Hope that answers your question.
Regards Derek H

Yes, I needed that to really "lodge" the information into place, thanks!
