How are leg types defined in RNAV procedure?
2. RNAV Leg Types. A leg type describes the desired path proceeding, following, or between waypoints on an RNAV procedure. Leg types are identified by a two-letter code that describes the path (e.g., heading, course, track, etc.) and the termination point (e.g., the path terminates at an altitude, distance, fix, etc.).
What do you call a track to fix leg?
A Track to Fix (TF) leg is intercepted and acquired as the flight track to the following waypoint. Track to a Fix legs are sometimes called point-to-point legs for this reason. Narrative: “on track 087 to CHEZZ WP.” See FIG 1-2-2.
Which is a direct to fix ( DF ) leg?
A Direct to Fix (DF) leg is a path described by an aircraft’s track from an initial area direct to the next waypoint. Narrative:“left turn direct BARGN WP.” See FIG 1-2-3. FIG 1-2-2 Track to Fix Leg Type FIG 1-2-3 Direct to Fix Leg Type c) Course to Fix.
Who is responsible for the operation of navigation aids?
The FAA has the statutory authority to establish, operate, maintain air navigation facilities and to prescribe standards for the operation of any of these aids which are used for instrument flight in federally controlled airspace. These aids are tabulated in the Chart Supplement U.S.
RNAV Leg Types. A leg type describes the desired path proceeding, following, or between waypoints on an RNAV procedure.

How are leg types identified in an aircraft?
Leg types are identified by a two-letter code that describes the path (e.g., heading, course, track, etc.) and the termination point (e.g., the path terminates at an altitude, distance, fix, etc.). Leg types used for procedure design are included in the aircraft navigation database, but not normally provided on the procedure chart.
How is a radius to fix ( RF ) leg defined?
A Radius to Fix (RF) leg is defined as a constant radius circular path around a defined turn center that terminates at a fix. See FIG ENR 1.17-6 . Heading. A Heading leg may be defined as, but not limited to, a Heading to Altitude (VA), Heading to DME range (VD), and Heading to Manual Termination, i.e., Vector (VM).
