In this part of the video, the narrator explains that standard instrument approach procedures (IAPs) in the U.S. are based on Terminal Procedures (TERPS), outlining the criteria for developing instrument approach procedures. Approach charts provide essential vertical and horizontal information for successful airport approaches. Jefferson introduced a new chart format called the briefing strip format, tested by various aviation professionals. The briefing strip format consists of four sections: heading, plan view, profile view, and landing minimums, arranged to help pilots review and use chart data effectively. The heading portion of the chart includes airport location details, procedure type, equipment requirements, index numbers, filing order, and revision dates. It is essential to use charts with current and up-to-date information.
00:05:00
In this segment of the video, the speaker discusses the airport identifier for Dallas Fort Worth International Airport (DFW) and details about the approach section in an approach chart. Key points include the communication frequencies for arrival, navigation aids, final approach course, altitude information, missed approach procedure, and minimum safe altitude (MSA) for obstacle clearance. Additionally, the speaker explains that MSA is based on the primary navigation facility, with adjustments made if full azimuth reference information is not available. The plan view section of the chart provides an overhead perspective of the approach procedure and surrounding airport vicinity with a mileage scale for distance measurement.
00:10:00
In this segment of the video, the narrator discusses the depiction of latitude and longitude lines on approach charts, primary airports with runway layouts, nearby airports with instrument approaches, and significant orientation details like terrain high points and man-made structures. It’s highlighted that structures above 400 feet above airport elevation are shown, along with symbols representing terrain features. The video emphasizes the importance of not relying solely on depicted terrain and obstruction altitudes for descent. Navigational aid symbols and information are detailed, including VORs, DMEs, and other facilities, with various symbols and identifiers explained. Approach transitions, obstacle clearances, and flyable routes on the chart are also discussed, stressing the distinction between flyable routes and radials or bearings. Initial approach fixes, minimum altitudes, and guidance on how to identify flyable routes are explained in this section.
00:15:00
In this segment of the video, the speaker explains the different segments of an approach procedure, including the initial approach segment, course reversals, intermediate segment, and final approach segment. They detail the altitude clearances, distances, and specific procedures for each segment. The profile view of Jefferson approach charts is discussed, emphasizing the depiction of altitudes, fixes, distances, and magnetic courses. The video also covers mandatory altitudes, course reversals, and procedure turn requirements, providing insights into interpreting profile views for approach procedures.
00:20:00
In this segment of the video, various important points about approach charts are discussed. This includes details about the final approach fix, glide slope indicators, missed approach procedures, threshold crossing height, touchdown zone elevation, and distance markers on the chart. Additionally, variations such as visual descent points and conversion tables for maintaining a glide slope are explained. Different information in the conversion chart based on ground speed and descent rate for precision approaches is highlighted, as well as timing considerations for non-precision approaches.
00:25:00
In this segment of the video, the lighting box on approach charts displays symbols representing the type of lighting installed for a runway. PAPI or VASIS indicators are shown on the left or right side corresponding to the runway. Missed approach information is depicted with icons on the chart, detailing procedures like climbing to specific altitudes and following designated routes. The landing minimum section outlines minimum altitudes and visibility requirements, which can vary based on the aircraft category and operational components. Decision altitudes and heights, as well as varying visibility requirements for different inoperative components, are explained. Minimums are categorically divided, and missed approach procedures are detailed, emphasizing the importance of understanding and following these guidelines accurately.
00:30:00
In this segment of the video, the speaker discusses circle-to-land minimum altitudes, approach categories, and various approach details. The protected airspace during a circle-to-land maneuver differs based on the aircraft’s approach category. It is essential to adhere to speed limits for obstacle clearance. The altitudes shown are above the airport and not the touchdown zone. Circling approaches may have limitations due to obstructions. Straight-in landing minimums are omitted if the final approach is misaligned. Different minimums apply if a specific DME fix is identified. Category two and three ILS approaches have lower minimums and require specialized equipment and pilot authorization. Required Navigation Performance (RNP) is introduced to offer greater flexibility in defining routes and airspace, transforming navigation technology.
00:35:00
In this segment of the video, the speaker explains the concept of Required Navigation Performance (RNP) levels, which are expressed in nautical miles. Currently, in the United States, there are three RNP levels: 0.3, 1.0, and 2.0. RNP 0.3 represents the highest level and is used for final approach segments, RNP 1.0 for defining terminal routes, and RNP 2.0 for enroute operations. The speaker emphasizes the importance of understanding aircraft requirements for operation in a given RNP environment and notifying air traffic control of any equipment failure. The video highlights the implementation of a worldwide RNP standard and the upcoming GNSS Landing System (GLS) as the next generation of air navigation. GLS will enhance GPS signals for various types of approaches and navigation systems, supporting the integration of area navigation into the national airspace system. New charting formats for RNP procedures aim to avoid duplication and simplify approach procedures, with specific details and requirements outlined on RNP charts.
00:40:00
In this segment of the video, the importance of understanding operational capabilities of GPS/FMS systems for compliance with vertical navigation requirements is highlighted. Differences in Minimum Safe Altitude (MSA) being waypoint-based rather than facility-based are explained. Terminal Arrival Areas (TAA) are introduced as efficient transition points for aircraft, reducing the need for procedure turns. Flyover and flyby waypoints are discussed, impacting approach procedures. Vertical navigation information in the profile view of an RNAV chart, including descent path guidance and ground speed information, is emphasized for stabilized descents. The appearance of notes on non-precision approaches, such as VNAV Decision Altitude (DHA) authorization, is detailed. Lastly, a new descent minimum format and terminology on RNAV charts, including minimums for LNAV, VNAV, and circling approaches, is mentioned.
00:45:00
In this part of the video, it is explained how aircraft capable of using RNAV (Rnav) with vertical guidance (VNAV) can make their final descent using a descent path generated by onboard navigation equipment. The minimums will be published and flown as a decision altitude. Elnav minimums are for non-precision approaches with only lateral navigation. Pilots need to consider the notes and plan view on charts when using RNAV procedures. The pilot carries the responsibility in determining the ability to use RNAV procedures, as these approaches are increasing. Continual updates are made to regulations to expand RNAV use, and pilots can contact their local Flight Standards District Office (FSDO) for guidance on RNAV operations.
