H (High Altitude) VOR Standard Service Volume
Asked by: skyfly 15665 views Airspace, FAA Regulations, Instrument Rating
The High Altitude VOR Standard Service Volume in the AIM has three different parts to it. The first one says “From 1,000 feet AGL up to and including 14,500 feet AGL at radial distances out to 40 NM.” I understand that.
Now the next two confuse me:
“From 14,500 AGL up to and including 60,000 feet at radial distances out to 100 NM”.
And
“From 18,000 feet AGL up to and including 45,000 feet AGL at radial distances out to 130 NM”.
I understand from 14,500 AGL the standard service volume increases from 40 NM to 100 NM and from 18,000 feet AGL it increases to 130 NM.
It’s the 60,000 and 45,000 AGL part that’s confusing me. If I’m at 30,000 feet is the service volume 100 NM or 130 NM? In what situations would I use one or the other? Please put this into one or more scenario(s) so I can understand.
Thank you!
