Leg Types

Type Support in A32NX Description
TF Complete Track to a fix defines a great circle track over ground between two known databases fixes.
RF Complete Constant Radius Arc defines a constant radius turn between two database fixes, lines tangent to the arc and a center fix.
VM Partial Heading to a manual termination defines a specified heading until a Manual termination.
AF Partial Arc to a fix defines a track over the ground at a specified constant distance from a database DME NAVAID.
CA Partial Course to an altitude defines a specified course to a specific altitude at an unspecified position.
CF Complete Course To fix defines a specified course to a specific database fix.
CI Partial Course to an intercept defines a specified course to intercept a subsequent leg.
CR Partial Course to a radial termination defines a course to a specified radial from a specific database VOR NAVAID.
DF Complete Direct To fix defines an unspecified track starting from an undefined position to a specified fix.
HA, HF, HM Complete Racetrack course reversal (Holds) or altitude termination (HA), single circuit terminating at the fix (base turn) (HF), or manual termination (HM) leg types define racetrack pattern or course reversals at a specified database fix.
IF Complete Initial fix defines a database fix as a point in space and is only required to define the beginning of a route or procedure.
CD Partial Course to a DME distance defines a specified course to a specific DME distance that is from a specific database DME NAVAID.
FA Partial Fix to an Altitude defines a specified track over the ground from a database fix to a specified altitude at an unspecified position.
FC Partial Track from a fix from a distance or FC leg—defines a specified track over the ground from a database fix for a specific distance.
FD Partial Track from a fix to a distance measuring equipment (DME) distance defines a specified track over the ground from a database fix to a specific DME distance that is from a specific database DME NAVAID.
FM Partial Fix to a manual termination or FM leg— defines a specified track over the ground from a database fix until manual termination of the leg.
PI Planned Procedure turn or PI leg—defines a course reversal starting at a specific database fix and includes outbound leg followed by a left or right turn and 180° course reversal to intercept the next leg.
VA Partial Heading to Altitude termination defines a specified heading to a specific altitude termination at an unspecified position.
VD Partial Heading to a DME distance termination defines a specified heading terminating at a specified DME distance from a specific database DME NAVAID.
VI Partial Heading to a Next Leg Intercept defines a specified heading to intercept the subsequent leg at an unspecified position.
VR Partial Heading to a radial termination defines a specified heading to a specified radial from a specific database VOR NAVAID.

Leg types marked as partially supported use an approximation that is usually very close or the same as a complete implementation. Complete implementation of all leg types is planned.
