Mar 20, 2020 · A short article merging airworthiness requirements with operational procedures to enable flight crews to cope with RF legs.

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 1-2-6.

An RF leg is defined by a radius, arc length, and a fix. Not all RNP capable FMS systems support RF legs. Use of RF legs is allowed prior to the Final Approach Fix.

identifies the optional capabilities (e.g., RF legs and RNP missed approaches), the RNP capability of each aircraft configuration, and the navigation system characteristics that may require …

constructed with Radius-to-Fix (RF) leg types and procedures using Track-to-Fix (TF) leg types. Please see attached recommendation document for a complete discussion of RF/TF …

RF legs are an RNAV leg type unlike the similar AF leg which is a DME arc that can be flown with a DME. Realistically, you will only find RF legs within SIDs, STARs, and IAPs as that's where …

May 19, 2019 · Radius-to-fix (RF) leg capability allows for a constant radius turn starting and ending on a fix or waypoint. The FMS computes the actual flight path, providing for repeatable …

RNP AR APCH with RF Legs •For approaches where RF legs are used (indicated on chart): –Navigation system must have the capability to execute RF legs between two fixes –Aircraft …

Nov 12, 2019 · The RF leg type is used on new Required Navigation Performance (RNP) approaches that fly curved paths. Turn radius is dependent on airspeed, winds and bank …

Jul 18, 2011 · The arc on a RF leg can be based on a radius equal to twice the RNP for the segment and is limited in bank angle below 500 feet to less than or equal to 3 degrees, but …
