Precision Approaches - Task code prefix: AA.VI.E - Official references: 14 CFR parts 91, 97; AIM; Chart Supplements; FAA-H-8083-2, FAA-H-8083-3, FAA-H-8083-15, FAA-H-8083-16, FAA-H-8083-25; Terminal Procedures Publications - FAA source library: https://www.faa.gov/training_testing/testing/acs ## Official Task objective To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with performing precision approach procedures. ## Knowledge elements - **AA.VI.E.K1** — Procedures and limitations associated with a precision approach, including determining required descent rates and adjusting minimums in the case of inoperative equipment. - **AA.VI.E.K2** — Navigation system displays, annunciations, and modes of operation. - **AA.VI.E.K3** — Ground-based and satellite-based navigation systems (orientation, course determination, equipment, tests and regulations, interference, appropriate use of navigation data, signal integrity). - **AA.VI.E.K4** — A stabilized approach, including energy management concepts. ## Risk management elements - **AA.VI.E.R1** — Deviating from the assigned approach procedure. - **AA.VI.E.R2** — Selecting a navigation frequency. - **AA.VI.E.R3** — Management of automated navigation and autoflight systems. - **AA.VI.E.R4** — Aircraft configuration during an approach and missed approach. - **AA.VI.E.R5** — An unstable approach, including excessive descent rates. - **AA.VI.E.R6** — Deteriorating weather conditions on approach. - **AA.VI.E.R7** — Continuing to descend below the Decision Altitude (DA)/Decision Height (DH) when the required visual references are not visible. ## Skills elements - **AA.VI.E.S1** — Accomplish the precision instrument approaches selected by the evaluator. - **AA.VI.E.S2** — Establish two-way communications with air traffic control (ATC) appropriate for the phase of flight or approach segment, and use proper communication phraseology. - **AA.VI.E.S3** — Select, tune, identify, and confirm the operational status of navigation equipment to be used for the approach. - **AA.VI.E.S4** — Comply in a timely manner with all clearances, instructions, and procedures. - **AA.VI.E.S5** — Recognize if any flight instrumentation is inaccurate or inoperative, and take appropriate action. - **AA.VI.E.S6** — Advise ATC or the evaluator if unable to comply with a clearance. - **AA.VI.E.S7** — Coordinate with crew, if applicable, and complete the appropriate checklist(s) in a timely manner. - **AA.VI.E.S8** — Establish the appropriate airplane configuration and airspeed considering meteorological and operating conditions. - **AA.VI.E.S9** — Maintain altitude ±100 feet, selected heading ±5°, airspeed ±10 knots, and accurately track radials, courses, and bearings, prior to beginning the final approach segment. - **AA.VI.E.S10** — Adjust the published DA/DH and visibility criteria for the aircraft approach category, as appropriate, to account for NOTAMS, inoperative airplane or navigation equipment, or inoperative visual aids associated with the landing environment. - **AA.VI.E.S11** — Establish a predetermined rate of descent at the point where vertical guidance begins, which approximates that required for the aircraft to follow the vertical guidance. - **AA.VI.E.S12** — Maintain a stabilized final approach from the Final Approach Fix (FAF) to DA/DH allowing no more than ¼-scale deflection of either the vertical or lateral guidance indications and maintain the desired airspeed ±5 knots. - **AA.VI.E.S13** — Upon reaching the DA/DH, immediately initiate the missed approach procedures if the required visual references for the runway are not distinctly visible and identifiable (or if in a seaplane); or transition to a normal landing approach only when the aircraft is in a position from which a descent to a landing on the runway can be made at a normal rate of descent using normal maneuvering. - **AA.VI.E.S14** — Use an MFD and other graphical navigation displays, if installed, to monitor position, track wind drift and other parameters to maintain desired flightpath. ## Difficulty methodology Difficulty calibration is ongoing for this Task. Observed difficulty is a privacy-thresholded check-ride.ai mock-oral practice proxy, not an FAA practical-test pass or fail rate. Underlying sample sizes and the private reporting threshold are not published. ## Official Task notes - See Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task. ## Use in practice A mock examiner can ask a pilot to explain the published elements, apply them to the configured aircraft and airport context, identify risks, and defend a decision. Practice prompts are not represented as actual FAA examiner scripts or predictions of the questions a candidate will receive.
