So you fly the KEA transition like this: Track RDL 265 KEA until crossing RDL 187 ATV or 27 DME KEA Start a right turn and intercept RDL 192 ATV Fly RDL192 until intercepting final As egid said, RDL 187 ATV is a lead radial which is a radial used only to tell you when to start a turn. As far as 20 DME ATV, it is actually only used for the PELAG transition ...

No. The FMS does not use rhumb lines. All RNP/RNAV flight path legs are geodesics. The only exceptions are RF legs (a constant radius circular path about a turn center) and hold legs (a closed racetrack pattern). To quote RTCA DO-236C, Minimum Aviation System Performance Standards: Required Navigation Performance for Area Navigation: RNP Routes and ...

The textual description says clearly: RWY track to 4.5 DME FFM/1.5 DME FRD or 800, whichever is later The equivalent encoding is: [A800+] - DF134 (25C)[L] / DF135 (25L)[L] The meaning of this is climb to an altitude of 800ft or above, then after passing DF134/DF135 turn left. From this EUROCONTROL document (Guidance Material for the Design of ...

These are RNAV procedures as defined in ARINC 424 used for database coding. They define paths which an aircraft must follow during RNAV departures and approaches. Every standard departure and approach can be divided into distinct sections. Each possible path starts at a point and ends at a termination point. The file format is standardized so that each and ...

The PBN manual is the place to start. In Section 5 on departure procedures it includes the following reference: b. Leg type limitations. See Order 8260.46, paragraph 3-1-5 for permissible leg types. Also, all the TERPS requirements also apply, except where modified by the PBN manual. There's usually no one rule that applies universally. It's about ...

Eurocontrol does offer the whole thing as well – albeit not for free as the FAA does. Check out https://www.eurocontrol.int/service/european-ais-database for more information.

It's in the Altitude/Minimum Altitude data field: 5.30 Altitude/Minimum Altitude Definition/Description: The Altitude/Minimum Altitude field indicates the reference altitude associated with (1) Enroute Airways (MEA, MFA or other minimum altitudes as defined by source), (2) holding pattern path of Holding Pattern record, (3) altitudes at fixes ...

As the name suggests, MEA is coded for enroute segments lik ethe airways (ARINC permits this). In so far as Instrument Approaches are concerned, the templates takes into account vertical clearances in Primary and secondary areas and then arrives at safe heights at each segment. Geometry of primary and secondary areas and the clearance therein depends on ...
