(See paragraph 5-4-18. 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." A variety of digital tools can help you in your flight planning, some of which include: There are many official sources from which to gather information pertinent to preflight planning, Note that though not required, it is recommended a call be placed to Flight Service prior to flight, You may wish to consider fuel prices, services available, landing fees, and hours of operation when planning for suitable diverts, Although these factors may run through your mind in an ad-hoc divert, that is a divert due to an unforeseen circumstance, then remember an airfield where a safe landing can be performed outweighs conveniences, Preflight planning feel monotonous when flying in the same region, weather conditions, and for the same purpose, In those situations, ask yourself, what is different today, to really drill down on what it is you need to pay attentiont o. ), You need not pass directly over a positive landmark for it to be useful to you, Be cautious of man-made landmarks as they may have changed, moved, or no longer exist, Water features are depicted using two tones of blue, and are considered either "Open Water" or "Inland Water", "Open Water," a lighter blue tone, shows the shoreline limitations of all coastal water features at the average (mean) high water levels for oceans and seas, Light blue also represents the connecting waters like bays, gulfs, sounds, fjords, and large estuaries, Exceptionally large lakes like the Great Lakes, Great Salt Lake, and Lake Okeechobee, etc., are considered Open Water features, The Open Water tone extends inland as far as necessary to adjoin the darker blue "Inland Water" tones, All other bodies of water are marked as "Inland Water" in the darker blue tone, Can be positively identified but not specifically plotted because they extend for some distance, Features such as roads, railroads, coastlines, power lines and rivers may make good timing checkpoints if they are perpendicular to the course line and have other specific environmental particulars that identify your position, Rivers and power lines must be easy to find, either isolated or large so they are unmistakable with confirming landmarks so they can be confirmed, Railroads and major highways are almost always depicted on aeronautical charts, Features that a pilot suspects he can correlate with the chart, but they may not be fully reliable, Landmarks such as oil wells, and windmills may be repetitious. Use of these reduced lateral accuracies will normally require use of the aircraft's autopilot and/or flight director. It is not intended for every operator or aircraft. Task B. Still looking for something? Flight Deck Management Lesson Plan - CFI Notebook 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.

About CFI Notebook If RAIM is not available, pilots need an approved alternate means of navigation, An aircraft is considered to be established on-course during RNAV and RNP operations anytime it is within 1 times the required accuracy for the segment being flown. This includes terrain, navaid coverage, emergency options, etc. Use of RNP 0.3 by slow-flying fixed-wing aircraft is under consideration, but the RNP 0.3 NavSpec initially will apply only to rotorcraft operations. Considerations for selection of either are: Are they small enough to be considered a "point? RF turn capability is optional in RNP 0.3 eligibility. Items listed in this PBN box are REQUIRED to fly the procedure's PBN elements. Copyright 2023 CFI Notebook, All rights reserved. At the alternate airport, pilots may plan for applicable alternate airport weather minimums using: Lateral navigation (LNAV) or circling minimum descent altitude (MDA); LNAV/vertical navigation (LNAV/VNAV) DA, if equipped with and using approved barometric vertical navigation (baroVNAV) equipment; RNP 0.3 DA on an RNAV (RNP) IAP, if they are specifically authorized users using approved baroVNAV equipment and the pilot has verified required navigation performance (RNP) availability through an approved prediction program, If the above conditions cannot be met, any required alternate airport must have an approved instrument approach procedure other than GPS that is anticipated to be operational and available at the estimated time of arrival, and which the aircraft is equipped to fly, This restriction does not apply to TSOC145() and TSOC146() equipped users (WAAS users), The low-strength data transmission signals from GPS satellites are vulnerable to various anomalies that can significantly reduce the reliability of the navigation signal. | Privacy Policy | Terms of Service | Sitemap | Patreon | Contact, Advisory Circular (91-92) Pilot's Guide to a Preflight Briefing. NavSpecs should be considered different from one another, not "better" or "worse" based on the described lateral navigation accuracy.

CFI Notebook: "Higher" Education As wind gets factored in, even if a round trip with consistent winds, the time to fly becomes longer - headwinds/tailwinds will not cancel out (see: Suppose D = distance, TT = total time, AS = air speed, WS = wind speed, Then the equation for a direct headwind and tail wind is TT = D/(AS - WS) + D/(AS + WS) = 150/(100 - 50) + 150/(100 + 50) = 150/50 + 150/150 = 450/150 + 150/150 = 600/150 = 4, With WS = 0 the equation becomes TT = 150/100 + 150/100 = 300/100 = 3, You will travel 10% of speed in 6 minutes.

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. Certified Flight Instructor Notebook The objective of IFR en route flight is to navigate within the lateral limits of a designated airway at an altitude consistent with the ATC clearance 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 Operators of GPS aircraft should always check for GPS and/or WAAS NOTAMS for their route of flight, GPS is a critical component of essential communication, navigation, and surveillance (CNS) in the NAS; and flight safety/control systems. Within PBN there are two main categories of navigation methods: In this context, the term RNAV "x" means a specific navigation specification with a specified lateral accuracy value, For an aircraft to meet the requirements of PBN, a specified RNAV or RNP accuracy must be met 95 percent of the flight time, RNP is an RNAV system that includes onboard performance monitoring and alerting capability (for example, Receiver Autonomous Integrity Monitoring (RAIM)), PBN also introduces the concept of navigation specifications (Nav Specs) which are a set of aircraft and aircrew requirements needed to support a navigation application within a defined airspace concept, For both RNP and RNAV NavSpecs, the numerical designation refers to the lateral navigation accuracy in nautical miles which is expected to be achieved at least 95 percent of the flight time by the population of aircraft operating within the airspace, route, or procedure, This information is detailed in International Civil Aviation Organization's (ICAO) Doc 9613, Performance-based Navigation (PBN) Manual and the latest FAA AC 90-105, Approval Guidance for RNP Operations and Barometric Vertical Navigation in the U.S. National Airspace System and in Remote and Oceanic Airspace, RNAV is a method of navigation that permits aircraft operation on any desired flight path within the coverage of ground- or space-based navigation aids or within the limits of the capability of self-contained aids, or a combination of these. Introduction: Flight planning is the process in whatever a pilot readies for somebody upcoming flight . One engine inoperative during straight-and-level flight and turns (AMEL, AMES) Task C. One Engine Inoperative - Instrument Approach (AMEL, AMES) Task D. Approach with Loss of Primary Flight Instrument Indicators. For procedures with PBN elements, the "PBN box" will contain the procedure's NavSpec(s); and, if required: specific sensors or infrastructure needed for the navigation solution, any additional or advanced functional requirements, the minimum RNP value, and any amplifying remarks. Typically, an aircraft eligible for A-RNP will also be eligible for operations comprising: RNP APCH, RNP/RNAV 1, RNP/RNAV 2, RNP 4, and RNP/RNAV 10. Copyright 2023 CFI Notebook, All rights reserved. The two terms, often used interchangeably, in fact mean different things: Courses are the direction which the aircraft is actually traveling (impacted by winds), Headings are the directions which the aircraft faces (where it is pointed). | 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."
