# How are there some Victor airways that exceed the service area of the VORs they are identified by?

As you can see here, V267 has a length of 149nm, is defined by the Craig VOR (CRG) and the Dublin VOR (DBN) and has a MEA of 3000. According to the AIM, the Service volumes of VORs never reach more then 40nm underneath 14,500ft.

Yes, the Craig VOR or rather VORTAC is described to have the Standart High Altitude Service Volume in the A/FD, but at the MEA, which should also guarantee reception of the navaids in use, the range is still only 40nm. A route at that altitude between those two navaids should only be <80nm, so how can it be 149nm?

• and the limitations are real. These are for DBN: HIWAS BROADCAST. VOR PORTION UNUSABLE 215-285 BYD 10NM BLO 3,500 FT. VOR PORTION UNUSABLE 001-139 BYD 33 NM ALL ALT. VOR PORTION UNUSABLE 001-139 BLO 5,000 FT AL DIST.  – rbp Feb 2 '15 at 20:21
