RF Legs
Vectors to Final
For details regarding RF legs for specific aircraft, consult the AFMS.
Activating vectors-to-final while on the From side of the final approach fix
suspends automatic waypoint sequencing. “SUSP” annunciates at the bottom of
the screen. Sequencing resumes once the aircraft is on the To side of the final
approach fix and within full-scale deflection.
AC 90-101A - RF Legs
AC 90-101A defines RF leg as
“A constant radius circular path,
around a defined turn center, that
starts and terminates at a fix. An
RF leg may be published as part of
a procedure.”
The unit supports radius-to-fix (RF)
legs associated with RNAV RNP 1.0
non-AR approaches, when approved by
the installation.
Flying a radius-to-fix approach is similar
to flying a DME arc approach (status
indications are identical).
Unlike DME arcs, however, RF legs are
not based on a VOR. They may have
varying radii, making them larger or
smaller than arc legs.
Activating the approach with vectors to final displays an
extension of the final approach course on Map.
Magenta depicts the active leg of
the flight plan.
CDI needle remains off center until you are established on
the final approach course. As a reminder, “vtf”
annunciates as part of the active leg on the GPS Nav
status key.
