No other modification of database waypoints or the creation of user-defined waypoints on published RNAV or RNP procedures is permitted, except to: Change altitude and/or airspeed waypoint constraints to comply with an ATC clearance/instruction, Insert a waypoint along the published route to assist in complying with ATC instruction, example, "Descend via the WILMS arrival except cross 30 north of BRUCE at/or below FL 210." ", [Figure 1-4] Boundaries separating the jurisdiction of Air Route Traffic Control Centers (ARTCC) are depicted on charts with blue serrations, The name of the controlling facility is printed on the corresponding side of the division line, ARTCC remote sites are depicted as blue serrated boxes and contain the center name, sector name, and the sector frequency. | Privacy Policy | Terms of Service | Sitemap | Patreon | Contact, Federal Aviation Administration - Pilot/Controller Glossary, CFI Notebook.net - Airways and Route Course Navigation, Instrument Flying Handbook (1-6) IFR En-Route Charts, The objective of IFR en route flight is to navigate within the, Your ability to fly instruments safely and competently in the system is greatly enhanced by understanding the vast array of data available to the pilot on instrument charts, En route high-altitude charts provide aeronautical information for en route instrument navigation at or above 18,000' MSL, Information includes the portrayal of Jet and RNAV routes, identification and frequencies of radio aids, selected airports, distances, time zones, special use airspace, and related information, Established jet routes from 18,000' MSL to FL 450 use NAVAIDs not more than 260 NM apart, To effectively depart from one airport and navigate en route under instrument conditions, a pilot needs the appropriate IFR en route low-altitude chart(s), The IFR low altitude en route chart is the instrument equivalent of the sectional chart, When folded, the cover of the AeroNav Products en route chart displays an index map of the United States showing the coverage areas, Cities near congested airspace are shown in black type and their associated area chart is listed in the box in the lower left-hand corner of the map coverage box, Also noted is an explanation of the off-route obstruction clearance altitude (OROCA), The effective date of the chart is printed on the other side of the folded chart, Information concerning MTRs is also included on the chart cover, The en route charts are revised every 56 days, When the AeroNav Products en route chart is unfolded, the legend is displayed and provides information concerning airports, NAVAIDs, communications, air traffic services, and airspace, Airport information is provided in the legend, and the symbols used for the airport name, elevation, and runway length are similar to the sectional chart presentation, Associated city names are shown for public airports only, FAA identifiers are shown for all airports, ICAO identifiers are also shown for airports outside of the contiguous United States, Instrument approaches can be found at airports with blue or green symbols, while the brown airport symbol denotes airports that do not have instrument approaches, Stars are used to indicate the part-time nature of tower operations, Automatic Terminal Information Service (ATIS) frequencies, part-time or on request lighting facilities, and part-time airspace classifications, The minimum en route altitude (MEA) ensures a navigation signal strong enough for adequate reception by the aircraft navigation (NAV) receiver and obstacle clearance along the airway, Communication is not necessarily guaranteed with MEA compliance, The obstacle clearance, within the limits of the airway, is typically 1,000' in non-mountainous areas and 2,000' in designated mountainous areas, MEAs can be authorized with breaks in the signal coverage; if this is the case, the AeroNav Products en route chart notes "MEA GAP" parallel to the affected airway, MEAs are usually bidirectional; however, they can be single-directional, Arrows are used to indicate the direction to which the MEA applies, The minimum obstruction clearance altitude (MOCA), as the name suggests, provides the same obstruction clearance as an MEA; however, the NAV signal reception is ensured only within 22 NM of the closest NAVAID defining the route, The MOCA is listed below the MEA and indicated on AeroNav Products charts by a leading asterisk (e.g., "*3400" - see Figure 1-2, V287 at bottom left), The minimum reception altitude (MRA) identifies the lowest altitude at which an intersection can be determined from an off-course NAVAID, If the reception is line-of-sight based, signal coverage only extends to the MRA or above, However, if the aircraft is equipped with distance measuring equipment (DME) and the chart indicates the intersection can be identified with such equipment, the pilot could define the fix without attaining the MRA, On AeroNav Products charts, the MRA is indicated by the symbol, The minimum crossing altitude (MCA) is charted when a higher MEA route segment is approached, The MCA is usually indicated when a pilot is approaching steeply rising terrain and obstacle clearance and/or signal reception is compromised, In this case, the pilot is required to initiate a climb so the MCA is reached by the time the intersection is crossed, On AeroNav Products charts, the MCA is indicated by the symbol, The maximum authorized altitude (MAA) is the highest altitude at which the airway can be flown with assurance of receiving adequate navigation signals, Chart depictions appear as "MAA-15000." An RNAV system with DME/DME/IRU inputs that is compliant with the equipment provisions of AC 90-100A, U.S. Terminal and En Route Area Navigation (RNAV) Operations, for RNAV routes. When operating below 18,000 feet MSL and: When operating above 18,000 feet MSL, maintain the altitude or flight level assigned by ATC, Account for changes in direction of flight along a flight plan and corresponding altitude changes to meet the standard, ATC may give other restrictions if you are under their control, say with, IFR Cruising Altitudes can be found by referencing FAR 91.179. Although the appropriate response will vary with the situation, in general pilots should: Use the last reliable navigation information as the basis for initial headings, and climb above terrain, Change to another source of navigation, if available (i.e., VOR, DME radar vectors), Pilots should promptly notify ATC if they experience GPS anomalies. When installed in accordance with appropriate airworthiness installation requirements and operated in accordance with applicable operational guidance (e.g., aircraft flight manual and Advisory Circular material), the following systems qualify as a suitable RNAV system: An RNAV system with TSO-C129/-C145/-C146 equipment, installed in accordance with AC 20-138, Airworthiness Approval of Global Positioning System (GPS) Navigation Equipment for Use as a VFR and IFR Supplemental Navigation System, and authorized for instrument flight rules (IFR) en route and terminal operations (including those systems previously qualified for "GPS in lieu of ADF or DME" operations), or. Still looking for something? Transmission and utility lines often span approaches to runways, natural flyways, such as lakes, rivers, gorges, and canyons, and cross other landmarks pilots frequently follow, such as highway, railroad tracks, etc. Additionally, some satellite communications avionics use GPS signals for operations in oceanic and remote airspaces. Continue searching. That required capability will be listed in the PBN box. VFR Navigation charts consist of the following: Designed for visual navigation of slow to medium speed aircraft, The topographic information consists of contour lines, shaded relief, drainage patterns, and an extensive selection of visual checkpoints and landmarks used for flight under VFR, Cultural features include cities and towns, roads, railroads, and other distinct landmarks, The aeronautical information includes visual and radio aids to navigation, airports, controlled airspace, special-use airspace, obstructions, and related data, Revised every 56 days, except most Alaskan charts are revised annually, TACs depict the airspace designated as Class B airspace, While similar to sectional charts, TACs have more detail because the scale is larger, Should be used by pilots intending to operate to or from airfields within or near Class B or class C airspace, Charted VFR Flyway Planning Charts are published on the back of the existing VFR Terminal Area Charts, Areas with TAC coverage are indication by a dot on the Sectional Chart indexes, Charts are revised every 56 days, except Puerto Rico-Virgin Islands revised annually, Designated primarily for helicopter operation in the Gulf of Mexico area, Information depicted includes offshore mineral leasing areas and blocks, oil drilling platforms, and high density helicopter activity areas, Covers the Grand Canyon National Park area and is designated to promote aviation safety, flight free zones, and facility VFR navigation in this popular area, The chart contains aeronautical information for general aviation for VFR pilots on one side and commercial VFR air tour operators on the other side, Caribbean 1 and 2 (CAC-1 and CAC-2) are designed for visual navigation to assist familiarization of foreign aeronautical and topographic information, The topographic information consists of contour lines, shaded relief, drainage patterns, and a selection of landmarks used for flight under VFR, A three-color chart series which shows current aeronautical information useful to helicopter pilots navigating in areas with high concentrations of helicopter activity, Information depiction includes helicopter routes, four classes of heliports with associated frequency and lighting capabilities, NAVAIDs, and obstructions, In addition, pictorial symbols, roads, and easily identified geographical features are portrayed, Have a longer life span than other charts and may be current for several years, updated as requested, Provide aeronautical information navigation under IFR conditions below 18,000' MSL, This four-color chart series includes airways; limits of controlled airspace; VHF NAVAIDs with frequency, identification, channel, geographic coordinates; airports with terminal air/ground communication; minimum en route and obstruction clearance altitudes; airway distances; reporting points; special use airspace; and military training routes, Scales vary from 1 inch = 5nm to 1 inch = 20nm, Area charts show congested terminal areas at large scale, They are included with subscriptions to any conterminous U.S. Set Low (full set, East or West sets), Designated for navigation at or above 18,000' MSL (up to FL 600), This four-color chart series includes the jet route structure; VHF NAVAIDs with frequency, identification, channel, geographic coordinates; selected airports; reporting points, Scales vary from 1 inch to 45nm to 1 inch = 18nm, TPPs are published in 24 loose-leaf or perfect bound volumes covering the conterminous U.S., Puerto Rico and the Virgin Islands, A Change Notice is published at the midpoint between revisions in bound volume format and is available on the internet for a free download at the AeroNav website, IAP charts portray the aeronautical data that is required to execute instrument approaches to airports, Each chart depicts the IAP, all related navigation data, communications information, and an airport sketch. Other methods providing an equivalent level of performance may also be acceptable, For RNAV 1 DPs and STARs, pilots of aircraft without GPS, using DME/DME/IRU, must ensure the aircraft navigation system position is confirmed, within 1,000 feet, at the start point of take-off roll. Can be used on any course that has adequate checkpoints, but is commonly used with dead reckoning and VFR radio navigation. ), The FAA and ICAO member states have led initiatives in implementing the RNP concept to oceanic operations, For example, RNP-10 routes have been established in the northern Pacific (NOPAC) which has increased capacity and efficiency by reducing the distance between tracks to 50 NM (See paragraph 4-7-1), Aircraft eligible for RNP operations will have an appropriate entry including special conditions and limitations in its AFM, avionics manual, or a supplement. Is time lost fighting a headwind gained back when riding a tailwind? Other methods providing an equivalent level of performance may also be acceptable, For procedures or routes requiring the use of GPS, if the navigation system does not automatically alert the flight crew of a loss of GPS, the operator must develop procedures to verify correct GPS operation, RNAV terminal procedures (DP and STAR) may be amended by ATC issuing radar vectors and/or clearances direct to a waypoint. Flight planning is the process in which a pilot prepares for an upcoming flight While often associated with completing a navigation log for a cross-country, flight planning is a process that must be conducted even for local flights in the traffic pattern It is a descriptive process therefore involving more than one type of navigation Routine checks of position against VOR or DME information, for example, could help detect a compromised GPS signal.

In the U.S., these minimum functions include capability to calculate and perform RF turns, scalable RNP, and parallel offset flight path generation. ), Similar to RNP AR approaches, RNP AR departure procedures have stringent equipage and pilot training standards and require special FAA authorization to fly. The file resolution is 300 dots per inch and the data is 8-bit color. The use of an automatic or manual runway update is an acceptable means of compliance with this requirement. If you are traveling at 100 knots ground speed for 6 minutes, how far will you travel? While there is a high expectation of knowledge among pilots, none can do so without periodically referencing old topics. For example, RNP 1 is different from RNAV 1, and an RNP 1 eligibility does NOT mean automatic RNP 2 or RNAV 1 eligibility. The system must be able to retrieve the procedure by name from the aircraft navigation database, not just as a manually entered series of waypoints, Whenever possible, RNAV routes (Q- or T-route) should be extracted from the database in their entirety, rather than loading RNAV route waypoints from the database into the flight plan individually. If you need to travel 10 NM, and you have a ground speed of 100 knots, how long will it take? XC Planning Checklist (Jeppeson GFM) Pilotage Navigation by reference to landmarks or checkpoints. Pilots should avoid premature manual deletion of waypoints from their active "legs" page to allow for rejoining procedures, RAIM Prediction: If TSO-C129 equipment is used to solely satisfy the RNAV and RNP requirement, GPS RAIM availability must be confirmed for the intended route of flight (route and time).

Additional data elements will be added in subsequent releases to include: departure procedures, standard terminal procedures. If you look for a specific instrument procedure in your aircraft's navigation database and cannot find it, it's likely that procedure contains PBN elements your aircraft is ineligible for or cannot compute and fly. Continue searching. Of greater and growing concern is the intentional and unauthorized interference of GPS signals by persons using "jammers" or "spoofers" to disrupt air navigation by interfering with the reception of valid satellite signals, The U.S. government regularly conducts GPS tests, training activities, and exercises that interfere with GPS signals. Automatic scaling and alerting changes are appropriate for some operations. While frequency associated with completing a navigation log for a cross-country, journey planning is a process that must be conducted even for local flights in the traffic pattern Are you an aircraft dispatcher or thinking with becoming one? Initial data elements included are: Airport and Helicopter Records, VHF and NDB Navigation aids, en route waypoints and airways. There are other objects or structures that could adversely affect your flight, such as construction cranes near an airport, newly constructed buildings, new towers, etc. The Chart Supplement U.S. shows data that cannot be readily depicted in graphic form; e.g. Considerations for selection of either are: Are they small enough to be considered a "point? The data is available by subscription only and is distributed on CD-ROM or by ftp download arrivals, and GPS/RNAV instrument approach, These digital VFR charts are geo-referenced images of FAA Sectional Aeronautical, TAC, and Helicopter Route charts.

Motivator: Cockpit management are the actions and procedures, starting with preflight, in which all necessary equipment, documents, checklists, and navigation charts appropriate for the flight are on board and easily accessible. In the U.S., a specific procedure's Performance-Based Navigation (PBN) requirements will be prominently displayed in separate, standardized notes boxes. Flight Management System (FMS): An FMS is an integrated suite of sensors, receivers, and computers, coupled with a navigation database These systems generally provide performance and RNAV guidance to displays and automatic flight control systems Inputs can be accepted from multiple sources such as GPS, DME, VOR, LOC and IRU Table of Contents Areas of Operation: Single-Engine Land I. Use the capabilities of your avionics suite to verify the appropriate waypoint and track data after loading the procedure from your database, Lateral Accuracy values are applicable to a selected airspace, route, or procedure, The lateral accuracy value is a value typically expressed as a distance in nautical miles from the intended centerline of a procedure, route, or path, RNP applications also account for potential errors at some multiple of lateral accuracy value (for example, twice the RNP lateral accuracy values), In the U.S., RNP APCH procedures are titled RNAV (GPS) and offer several lines of minima to accommodate varying levels of aircraft equipage: either lateral navigation (LNAV), LNAV/vertical navigation (LNAV/VNAV), Localizer Performance with Vertical Guidance (LPV), and Localizer Performance (LP). RNP AR DP is intended to provide specific benefits at specific locations. These events are geographically limited, coordinated, scheduled, and advertised via GPS and/or WAAS NOTAMS. [Figure 1-5], Intersections along the airway route are established by a variety of NAVAIDs, NDBs, localizers, and off-route VORs are used to establish intersections, NDBs are sometimes collocated with intersections, in which case passage of the NDB would mark the intersection, A bearing to an off-route NDB also can provide intersection identification, A localizer course used to identify an intersection is depicted by a feathered arrowhead symbol on the en route chart (, If feathered markings appear on the left-hand side of the arrowhead (, On AeroNav Products en route charts, the localizer symbol is only depicted to identify an intersection, Off-route VORs remain the most common means of identifying intersections when traveling on an airway, Another means of identifying an intersection is with the use of DME, If the DME mileage at the intersection is a cumulative distance of route segments, the mileage is totaled and indicated by a D-shaped symbol with a mileage number inside, [Figure 1-4] Approved IFR global positioning system (GPS) units can also be used to report intersections, DME and GPS provide valuable route information concerning such factors as mileage, position, and ground speed, Even without this equipment, information is provided on the charts for making the necessary calculations using time and distance, The en route chart depicts point-to-point distances on the airway system, Distances from VOR to VOR are charted with a number inside of a box, To differentiate distances when two airways coincide, the word "TO" with the three-letter VOR identifier appear to the left of the distance boxes, VOR changeover points (COPs) are depicted on the charts by this symbol, The numbers indicate the distance at which to change the VOR frequency, The frequency change might be required due to signal reception or conflicting frequencies, If a COP does not appear on an airway, the frequency should be changed midway between the facilities, A COP at an intersection may indicate a course change, Occasionally an "x" appears at a separated segment of an airway that is not an intersection, The "x" is a mileage breakdown or computer navigation fix and may indicate a course change, Today's computerized system of ATC has greatly reduced the need for holding en route, However, published holding patterns are still found on charts at junctures where ATC has deemed it necessary to enable traffic flow, When a holding pattern is charted, the controller may provide the holding direction and the statement "as published. RNP APCH has a lateral accuracy value of 1 in the terminal and missed approach segments and essentially scales to RNP 0.3 (or 40 meters with SBAS) in the final approach. Charts come in a large variety which fall under the following categories: Public sales of charts and publications are available through a network of FAA approved providers, A listing of products, dates of latest editions and agents is available on the. For some navigation systems and operations, manual selection of scaling will be necessary, Pilots flying FMS equipped aircraft with barometric vertical navigation (Baro-VNAV) may descend when the aircraft is established on-course following FMS leg transition to the next segment. GPS with or without Space-Based Augmentation System (SBAS) (for example, WAAS) can provide the lateral information to support LNAV minima. This is especially true when operating below 500' AGL and morseo below 200' AGL, Also, many of these structures do not meet charting requirements or may not yet be charted because of the charting cycle, Some structures do not require obstruction marking and/or lighting and some may not be marked and lighted even though the FAA recommended it, Notice to Air Missions (NOTAMs) will typically be published for any known unlit structures, but pilot vigilance is imperative in case the FAA has not yet been notified of outages, The glide distance of the airplane is based on the glide ratio, a performance number to provide an idea of the options available in an engine out, More than airports, suitable roads and fields options for emergency landings increases with increased altitude, Additionally, regulatory requirements, such as those found in FAR 91.205, specify supplemental survival equipment depending on glide-distance from shore if the flight is conducted for hire, Even further, FAR 91.509 further specifies supplemental survival equipment based on distance from shore, Winds are an important planning consideration both during terminal (surface winds) and cruise (winds aloft) environment, Surface winds are most commonly used for determining an optimal runway in the terminal area, Similarly, surface winds provide insight into optimal landing surfaces in an emergency along a route of flight, Wind direction and intensity at various cruise altitudes are an important consideration to determine cruise performance, Winds aloft are the most direct means to plan for winds at cruise altitudes along the route of flight, Headwinds increase flight time and therefore fuel burn, reducing range, while tailwinds do just the opposite, Further, headwinds require for power (increased fuel burn) and tailwinds decrease power requirements (decreased fuel burn), Except while holding in a holding pattern of 2 minutes or less (see. Other "advanced" options for use in the en route environment (such as fixed radius transitions and Time of Arrival Control) are optional in the U.S. Becomes difficult in low visibility or in areas that lack prominent features.

Pilots transitioning to VOR navigation in response to GPS anomalies should refer to the Chart Supplement U.S. to identify airports with available conventional approaches associated with the VOR Minimum Operational Network (MON) program. cfi. Pilots may descend when established on-course on the next segment of the approach, The Aircraft Flight Manual (AFM) or avionics documents for your aircraft should specifically state the aircraft's RNP eligibilities, Contact the manufacturer of the avionics or the aircraft if this information is missing or incomplete, U.S. standard NavSpecs above support typical RNP airspace however, other NavSpecs may include different lateral accuracy values as identified by ICAO or other states.
