FIG 1-2-4 FIG 1-2-6 Direct to Fix Leg Type Radius to Fix Leg Type (5) Heading. A Heading leg may be (3) Course to Fix. A Course to Fix (CF) defined as, but not limited to, a Heading to Altitude leg is a path that terminates at a fix with a specified (VA), Heading to DME range (VD), and Heading to course at that fix. Narrative: "on course 150 to Manual Termination, i.e., Vector (VM). Narra- ALPHA WP." See FIG 1-2-5. tive: "climb heading 350 to 1500", "heading 265, at 9 DME west of PXR VORTAC, right turn heading
FIG 1-2-5 360", "fly heading 090, expect radar vectors to Course to Fix Leg Type DRYHT INT." (c) Navigation Issues. Pilots should be aware of their navigation system inputs, alerts, and annunciations in order to make better-informed decisions. In addition, the availability and suitability of particular sensors/systems should be considered. (1) GPS/WAAS. Operators using TSO- C129(), TSO-C196(), TSO-C145() or TSO-C146() systems should ensure departure and arrival airports are entered to ensure proper RAIM availability and CDI sensitivity. (2) DME/DME. Operators should be aware that DME/DME position updating is depen- dent on navigation system logic and DME facility proximity, availability, geometry, and signal mask- ing. (3) VOR/DME. Unique VOR character- istics may result in less accurate values from VOR/DME position updating than from GPS or DME/DME position updating. (4) Inertial Navigation. Inertial reference (4) Radius to Fix. A Radius to Fix (RF) units and inertial navigation systems are often leg is defined as a constant radius circular path around coupled with other types of navigation inputs, a defined turn center that terminates at a fix. See e.g., DME/DME or GPS, to improve overall FIG 1-2-6. navigation system performance. Performance-Based Navigation (PBN) and Area Navigation (RNAV) 1-2-3
