2020年3月20日 · The main drivers to define turns with a fixed radius over ground are airspace usage optimization and challenging terrain or obstacle situations. RF legs have first been …

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 …

An RF leg is defined 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

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.

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 …

2019年5月19日 · 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 …

2011年7月18日 · 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 …

2014年12月30日 · 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 …

2018年4月23日 · RF 航段是从一个定位点以某一点为圆心，某一特定值为半径，飞行至另一个定位点的航段，可满足在地形复杂、偏远机场的越障需求，能够大幅提升航班运行能力与飞行安全 …
