This one stumped my CFI, and I can find no answer. In the DFW Bravo are 3 VORs: midfield is VOR/DME Maverick (TTT), about 10 Miles east is VOR/DME Cowboy (CVE), and about 10 Miles West is VORTAC Ranger (FUZ). Sectional chart shows radials at Maverick only. Terminal chart has radials at Maverick and Cowboy, even though they overlap. Ranger has no radials on either chart. Does anyone know why, and how to use a VOR with no radials?
