ONLINE COURSE Ref: C-OL-PBNDOC1 Page 1/3 Rev: 0 Date 01/01/2016 DEFINITIONS Aircraft-based Augmentation System (ABAS): A system that supplements other GNSS elements with information from augmentation systems. Airspace Concept: Overall strategic framework and plans for the operational use of an airspace in order to improve increased traffic capacity, safety and mitigation of environmental impact Approach Procedures with Vertical Guidance (APV): In instrument approach which utilizes both horizontal and vertical flight path information, within the coverage of a ground or aircraft based navigational system or a combination of both. ARINC 424: Structure or architecture agreed upon for navigation databases to standardize data within the system. AREA NAVIGATION (RNAV): Is a method of navigation that permits aircraft operation on any desired course within the coverage of station-referenced navigation signals or within the limits of a self-contained system capability, or a combination of the above. This is accomplished primarily with navigation referenced to GPS, in addition, the Flight Management Systems (FMS) will also auto tune VORs, DMEs and compare any additional navigational sources like IRUs, TACANs, ADFs and LORAN Cs that might be onboard to increase the precision of navigation. Basic Area Navigation (BRNAV): The capability of an aircraft to contain navigational accuracy within a radius of +/- 5 NM 95% of the time or RNP 5 through coverage of station-referenced navigation signals or within the limits of a self contained system capability, or a combination of these. Presently used for en route navigation in Europe. Barometric Altimetry: Barometric Altimetry provides readings based on atmospheric pressure Closed Termination: A RNAV Standard Arrival (RNAV STAR) procedure that allows the operator to fly from the entry point of the STAR to the Final Approach Fix or the termination of the STAR without input from ATC. CONDITIONAL WAYPOINT: ARINC 424 waypoint within the database indicated by two letters and three number (AB343) which has an assigned latitude and longitude for position within the procedure. These waypoints set some condition like altitude or airspeed limitation for the procedure flown. Course to a Fix: A heading given by ATC in the form of a radar vector or cleared “Direct to” to some fix, which ATC must compensate for, know wind drift Copyrights © by Flyco Training Solutions.

ONLINE COURSE Ref: C-OL-PBNDOC1 Page 2/3 Rev: 0 Date 01/01/2016 Fault Detection and Exclusion: Function performed by some GNSS which can detect a faulty satellite signal and exclude it from navigational use. FLY-BY waypoints: Where the navigation system anticipates the turn onto the next route leg. The aircraft turns early to intercept the new course on centerline. Requires advanced navigational functionality. The preferred method for waypoints in PRNAV and are indicated by a four pointed star. FLY-OVER waypoints: Where the aircraft over flies the waypoint before starting to turn onto the next route leg. Used only in the Terminal Area (TMA) usually for the Final Approach Fix (FAF) can be used in other areas when procedure requires passing over a fix prior to a turn. Indicated by a four-pointed star within a circle. FMS: Flight Management System An integrated system, consisting of airborne sensor, receiver and computer with both navigation and aircraft performance databases, which provides performance and RNAV guidance to a display and automatic flight control system. Open Transition: An RNAV STAR procedure that takes the operator from the entry point to a position on downwind for an approach and requires a radar vector from ATC to reach the Final Approach Fix or termination of the STAR. This method is used for aircraft spacing on final. GPS: NAVSTAR Global Positioning System, which uses satellites to determine positions on Earth. Inertial Reference System/Inertial Navigation System (IRS/INS) An aircraft on-board self-contained navigation system. (Requires no external navigation inform.) Named Waypoint: ARINC 424 terminator that represents a geographical position on the ground that is identified by a five-letter name (ROBSA). Navigation Database Integrity: All navigation databases used in modern aircraft today come from a common source, Jeppesen Charts. These charts are updated every 14 days and sent to pilots in the form of revisions to existing charts. After publication the charts are digitized for use in databases. The revisions, in this digitized form, are sent to the database manufactures such as Honeywell, Collins etc., for use in their systems. These companies use a computer integrity-checking program to assure the accuracy of the information. The programs check for waypoint accuracy (location via Lat/Long, naming, etc), bearing and distance to the next waypoint, any constraints such as airspeed or altitude, and if the waypoints are accurately listed as fly-by or fly-over waypoints. The Euro Control website, www.ecacnav.com, lists the databases that are currently compliant with TGL 10 requirements. Any database that is not compliant with TGL 10 computer integrity checking must use an alternate method to be compliant; these methods are listed in TGL 10. Copyrights © by Flyco Training Solutions.

ONLINE COURSE Ref: C-OL-PBNDOC1 Page 3/3 Rev: 0 Date 01/01/2016 Path and Terminator Concept: ARINC 424 basic design for database procedures, which consist of numerous waypoints or terminators connected by paths or tracks. Precision Area Navigation (PRNAV) or Future “Basic RNP-1” in PBN: Refers to precision navigation within the terminal area of the airport for departures or arrivals with a navigational accuracy of +/- 1 NM 95% of the time or a RNP 1. Coverage is provided by use of station-referenced navigation signals or within the limits of a self contained system capability, or a combination of these. Required Navigational Performance (RNP): The capability of an aircraft to contain navigational accuracy within a specified radius up to 95% of the time. For example, the requirement for Basic RNP-1 is an ability to maintain containment within +/- 1 NM of centerline 95% of the time. RNAV Standard Instrument Departure (SID) or Future “Basic RNP-1” SID in PBN: A published departure procedure from an airport to the en route airway structure that uses RNAV/RNP capability to navigate. RNAV Standard Arrival (STAR) or Future “Basic RNP-1” STAR in PBN: A published arrival procedure that transitions from the en route airway structure to the Final Approach Fix for an instrument approach in the terminal area using RNAV/RNP navigation capability. Track to a Fix: A course, which connects two terminators or waypoints within the database, controlled by the FMS to compensate for known wind drift. Displayed on the Navigation Display (ND) as a solid line connecting the waypoints. Copyrights © by Flyco Training Solutions. All rights reseved.
