I was looking at the L1/L2 chart between RBL (Red Bluff) and SAC
(Sacramento). The change over point is at GRIDD because the airway changes direction slightly. The only thing is, it shows the DME distance to GRIDD from SAC as being 55nm. If I'm below 14,500, don't all VORs have a service volume of 40nm out from the VOR? |

Class H & HW VORs:
Altitude Radius 1,000' to 14,500' 40 NM 14,500' to 18,000' 100NM 18,000 to 45,000' 130NM Class L & LW VORs: Altitude Radius 1,000' to 18,000' 40NM Class T VORs: Altitude Radius 1,000' to 12,000' 25NM I can't pull up the L1 / L2 chart or the A/FD right now. What class VOR is SAC and what is the MEA on that route? If the MEA is below 14,500' I'd guess that the route was test flown and shown that reliable coverage existed out to GRIDD.

SAC is a High VOR and the MEA is 4,000. Ok, so if it's published,
then it's known to be ok on the airway. I think I remember reading now that the volumes don't matter if it's a published procedure like on an approach plate.

Hmm, does anyone know where this is written? Does that mean if it's
80nm to the change over point from a VOR, and the MEA is 5,000, you can still use it at that altitude? On Feb 5, 1:38 pm, "kevmor" wrote: SAC is a High VOR and the MEA is 4,000.

If I'm below 14,500, don't all VORs have a service volume of 40nm out from the VOR? Standard Service Volume limitations do not apply to published IFR routes or procedures. When a procedures specialist requires the use of a NAVAID beyond the limitations specified for SSV, an Expanded Service volume may be established. The SAC VORTAC 329R has an ESV of 55NM at 4000. |

Thanks, I was almost looking right at it!

Service Volumes don't apply to airways. FAA Frequency Management and Flight Inspection supercede Service Volumes when airways are built. |
