Usually, the first indication of flying into restricted visibility conditions is the gradual disappearance of lights on the ground If the lights begin to take on an appearance of being surrounded by a halo or glow, the pilot should use caution in attempting further flight in that same direction See the latest AC 90-105 for more information on A-RNP, including NavSpec bundling options, eligibility determinations, and operations approvals, A-RNP eligible aircraft are NOT automatically eligible for RNP AR APCH or RNP AR DP operations, as RNP AR eligibility requires a separate determination process and special FAA authorization, RNP 1 requires a lateral accuracy value of 1 for arrival and departure in the terminal area, and the initial and intermediate approach phase when used on conventional procedures with PBN segments (for example, an ILS with a PBN feeder, IAF, or missed approach). GBAS Landing System (GLS) procedures are also constructed using RNP APCH NavSpecs and provide precision approach capability. Pilots are required to use SBAS to fly to the LPV or LP minima. Higher continuity (such as dual systems) may be required for certain oceanic and remote continental airspace. RF turn capability is optional in RNP 1 eligibility. and the termination point (e.g., the path terminates at an altitude, distance, fix, etc. National Geospatial-Intelligence Agency (NGA) Products: Flight Information Publication (FLIP) Planning Documents, FLIP En-route Charts and Chart Supplements, FLIP Instrument Approach Procedures (IAPs), International Civil Aviation Organization (ICAO), https://www.icao.int/publications/Pages/catalogue.aspx, Aeronautical Information Manual (9-1-1) General, Aeronautical Information Manual (9-1-2) Obtaining Aeronautical Charts, Aeronautical Information Manual (9-1-3) Selected Charts and Products Available, Aeronautical Information Manual (9-1-4) General Description of each Chart Series, Aeronautical Information Manual (9-1-5) Where and How to Get Charts of Foreign Areas, Federal Aviation Administration - Aeronautical Chart User's Guide, Federal Aviation Administration - AeroNav, Federal Aviation Administration - AeroNav Digital Products, Federal Aviation Administration - Pilot/Controller Glossary, Civil aeronautical charts for the U.S. and its territories and possessions are produced by the. Routine checks of position against VOR or DME information, for example, could help detect a compromised GPS signal. 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. 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 When flying GPS approaches, particularly in IMC, pilots should have a backup plan in the event of GPS anomalies. Magnetic heading will usually require a correction based on the variation or: The angular difference between true north and magnetic north from any given position on the earth's surface (represented by isogonic lines), Isogonic lines are points of equal variation, represented in degrees east or west, Deviations is usually pulled off a sectional chart however, other sources such as, The memory aide "east is least (minus), west is best (plus)" is often used to remember how to apply east and west variations, Magnetic Course (MC) = True Course (TC) - East Variation, Magnetic Course (MC) = True Course (TC) + West Variation, All aircraft will have a deviation factor that must be applied, Deviation is read off the compass card in the aircraft, and must be added or subtracted to the magnetic course as appropriate, Determining winds at altitude help guide your true heading, Since winds aloft are expressed in "true," you will calculate the wind correction angle off true course, Deviation is found on a placard with your magnetic compass, Variation is necessary for converting true headings to magnetic, Magnetic variation depends on your location on the earth, as labeled by isogonic lines, Compass heading is determined by applying the deviation correction to the magnetic heading, From Sea Level to 5,500' we calculate 9 minutes, 2.0 Gal, 13 NM, Assuming 1,000' for the departure altitude we calculate: 1 minute, 0.4 Gal, 2 NM, Subtract the difference: (9-1)=8 Min, (2.0-0.4)=1.6 Gal, (13-2)=11 NM, Pay attention to the notes at the bottom of the chart, especially to add 1.1 Gal for taxi and takeoff, Utilizing a simple formula (Distance = Time x Ground Speed may be utilized, Therefore, if you have any two, you can calculate the other. There are several potential advantages of RNAV routes and procedures: Reduced dependence on radar vectoring, altitude, and speed assignments allowing a reduction in required ATC radio transmissions, and, In addition to information found in this manual, guidance for domestic RNAV DPs, STARs, and routes may also be found in Advisory Circular 90-100(), U.S. Terminal and En Route Area Navigation (RNAV) Operations, RNAV procedures, such as DPs and STARs, demand strict pilot awareness and maintenance of the procedure centerline, Pilots should possess a working knowledge of their aircraft navigation system to ensure RNAV procedures are flown in an appropriate manner, In addition, pilots should have an understanding of the various waypoint and leg types used in RNAV procedures; these are discussed in more detail below, A waypoint is a predetermined geographical position that is defined in terms of latitude/longitude coordinates, Waypoints may be a simple named point in space or associated with existing navaids, intersections, or fixes, A waypoint is most often used to indicate a change in direction, speed, or altitude along the desired path, RNAV procedures make use of both fly-over and fly-by waypoints, Fly-by waypoints are used when an aircraft should begin a turn to the next course prior to reaching the waypoint separating the two route segments. 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. ), Advanced RNP is a NavSpec with a minimum set of mandatory functions enabled in the aircraft's avionics suite. Federal Aviation Administration - Pilot/Controller Glossary, FAR 91.103 that "Each pilot in command shall, before beginning a flight, become familiar with all available information concerning that flight" which includes, If you don't own an airplane, you probably rent your favorite aircraft at the same FBO each time you fly however, for many, that may not be a possibility, Variations in airplanes which you are licensed and probably signed off to rent by your local FBO must be considered, While normal procedures can generally be done at the pilot's pace, emergency procedures cannot, making their understanding crucial, Aircraft perform differently based on the environmentals and type of operation expected, Be cognizant of "what is different today" and brief to it up front, so factors like density altitude and weight and balance are taken into consideration, Review and print, or tab a copy of the arrival and departure airport, as required, Be wary of "expectation bias;" listen to what a controller actually says, not what you expect, Enroute sector boundaries can be found on enroute charts allowing you to anticipate where about a switch will occur, and to what frequency, Don't ignore what you are flying over as water conditions/temperatures and terrain may impact what you bring and how you may react to an emergency, Pilots must be familiar with what equipment is installed in the airplane, Just as important, pilots must be familiar with where that equipment is installed, The most obvious example is the instrument panel, where equipment like transponders maybe in a new location, even across the same brand of airplane but a different model, Less obvious examples are safety equipment. This is limited only to systems that allow along-track waypoint construction, Pilots of FMS-equipped aircraft, who are assigned an RNAV DP or STAR procedure and subsequently receive a change of runway, transition or procedure, must verify that the appropriate changes are loaded and available for navigation, For RNAV 1 DPs and STARs, pilots must use a CDI, flight director and/or autopilot, in lateral navigation mode. 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. (Reference AIM 1-1-3f). 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. For times under 3 minutes, the small arrow may need to be utilized, Navigation logs, or NAVLOGs, is the printed, either physically or digitally, plan, This plan accounts for the environment's effects on the aircraft, as well as aircraft anomolies like deviation, NAVLOGs come in many forms and there is no perfect form; its about personal preference. In the U.S., these minimum functions include capability to calculate and perform RF turns, scalable RNP, and parallel offset flight path generation. On procedures with both PBN elements and ground-based equipment requirements, the PBN requirements box will be listed first (See FIG 5-4-1. Information on available Canadian charts and publications may be obtained from designated FAA chart agents or by contacting the: Information on available Mexican charts and publications may be obtained by contacting: A free ICAO Publications and Audio-Visual Training Aids Catalogue is available from: The FAA publishes a list of charts and publications with the, Additional information regarding content on aeronautical charts can be found in the. Still looking for something? It includes aeronautical and topographic information of the conterminous U.S. That required capability will be listed in the PBN box. 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.
