Hello guys,

We had an argument in flight about plotting requirements. We have to plot (our company requires) if we're not within 725 miles from Nav-aid. My understanding is that Nav-aid can be anywhere around the aircraft outside 725 mi radius. Some one was saying it has to be along the route of flight, in front or behind the aircraft on the line of our course..
Also any one knows the history behind plotting?

Thanks,

Max
