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?


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.
