Re: Questions about the US from Australia
Spodman,
Yes the VOR coverage in the US is that good with minor exceptions in some remote areas.
As for giving direct, we do it all the time if the acft is RNAV, GPS, or FMS equiped.
For an aircraft that is only A (alpha) equipped, I use the following rule. I will give direct to a fix outside of my airspace IF the acft can receive and navigate direct to the fix before it leaves my airspace. If the acft can not receive and navigate direct to the fix on its' own before leaving my airspace I am required to verbally coodinate the issued heading with the next facility and that the acft is direct when able.
In a non-radar situation we put acft on the airways or jetways, right altitude for direction of flight, and require position reports.
