Instrument Rating Lesson Plans - CFI Notebook For example, while operating on a Q-Route (RNAV 2), the aircraft is considered to be established on-course when it is within 2 nm of the course centerline, Pilots must be aware of how their navigation system operates, along with any AFM limitations, and confirm that the aircraft's lateral deviation display (or map display if being used as an allowed alternate means) is suitable for the accuracy of the segment being flown. Copyright 2023 CFI Notebook, All rights reserved. When using full automation, pilots should monitor the aircraft to ensure the aircraft is turning at appropriate lead times and descending once established on-course, Pilots flying TSO-C129 navigation system equipped aircraft without full automation should use normal lead points to begin the turn. | Privacy Policy | Terms of Service | Sitemap | Patreon | Contact, Aeronautical Information Manual (1-2-2) Required Navigation Performance (RNP), Aeronautical Information Manual (5-1-16) RNAV and RNP Operations, Aeronautical Information Manual (5-5-16) RNAV and RNP Operations, Federal Aviation Administration - Pilot/Controller Glossary, Required Navigation Performance, or RNP, is RNAV with the added requirement for onboard performance monitoring and alerting (OBPMA), RNP standards are required for operation within a certain airspace, A critical component of RNP is the ability of the aircraft navigation system to monitor its achieved navigation performance, and to identify for the pilot whether the operational requirement is, or is not, being met during an operation, RNP capability of the aircraft is a major component in determining the separation criteria to ensure that the overall containment of the operation is met, OBPMA capability therefore allows a lessened reliance on air traffic control intervention and/or procedural separation to achieve the overall safety of the operation, The RNP capability of an aircraft will vary depending upon the aircraft equipment and the navigation infrastructure [, For example, an aircraft may be eligible for RNP 1, but may not be capable of RNP 1 operations due to limited NAVAID coverage or avionics failure. EPU may also be referred to as Actual Navigation Performance (ANP) or Estimated Position Error (EPE), If unable to comply with the requirements of an RNAV or RNP procedure, pilots must advise air traffic control as soon as possible. ), 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. This means that your aircraft may be eligible for RNP APCH operations, but you may not fly an RF turn unless RF turns are also specifically listed as a feature of your avionics suite.

Preflight Planning - CFI Notebook 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). 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. RNP AR DP has lateral accuracy values that can scale to no lower than RNP 0.3 in the initial departure flight path. RNP 0.3 is not authorized for oceanic, remote, or the final approach segment. The CFI, or Flight Instructor Notebook, is an instructor's guide to navigating the sea of resources to provide useful guidance for their students and themselves. ), The RNP 0.3 NavSpec requires a lateral accuracy value of 0.3 for all authorized phases of flight. 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. notebook-8/,$1 %/$1&+$5'. 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.
