), the applicant should be prepared for questions on any weather product presented in the references for that Task. The abbreviation(s) within parentheses immediately following a Task refer to the category and/or class aircraft appropriate to that Task. Those tasks that have the ATP abbreviation in parenthesis within the Task title (e.g., Weather Information (ATP)) are required for an ATP practical test, but are not required for a type rating only practical test. The meaning of each abbreviation is as follows. • ATP—ATP Certificate only • ASEL—Airplane – Single-Engine Land • ASES—Airplane – Single-Engine Sea • AMEL—Airplane – Multiengine Land • AMES—Airplane – Multiengine Sea ote:N When administering a test, the Tasks appropriate to the class airplane (ASEL, ASES, AMEL, or AMES) used for the test must be included in the plan of action. The FAA encourages applicants and instructors to use the ACS when preparing for the airman knowledge tests and practical tests. Evaluators must conduct the practical test in accordance with the current ACS and FAA regulations pursuant to 14 CFR part 61, section 61.43. If an applicant is entitled to credit for Areas of Operation previously passed as indicated on a Notice of Disapproval of Application or Letter of Discontinuance, evaluators shall use the ACS currently in effect on the date of the test. The ground portion of the practical test allows the evaluator to determine whether the applicant is sufficiently prepared to advance to the flight portion of the practical test. The applicant must pass the ground portion of the practical test before beginning the flight portion. The oral questioning will continue throughout the entire practical test. 61 Appendix 1: Practical Test Roles, Responsibilities, and OutcomesAirline Transport Pilot and Type Rating for Airplane Category ACS (FAA-S-ACS-11A) Instructor Responsibilities The instructor trains and qualifies the applicant to meet the established standards for knowledge, risk management, and skill elements in all Tasks appropriate to the certificate and rating sought. The instructor should use this ACS and its references when preparing the applicant to take the practical test and when retraining the applicant to proficiency in any subject(s) missed on the knowledge test. Evaluator Responsibilities An evaluator includes the following: • Aviation Safety Inspector (ASI); • Pilot examiner (other than administrative pilot examiners); • Training center evaluator (TCE); • Chief instructor, assistant chief instructor, or check instructor of pilot school holding examining authority; or • Instrument Flight Instructor (CFII) conducting an instrument proficiency check (IPC). The evaluator who conducts the practical test verifies the applicant has met the aeronautical experience requirements specified for a certificate or rating before administering the test. During the practical test, the evaluator determines whether the applicant meets the established standards of aeronautical knowledge, risk management, and skills for the Tasks in the appropriate ACS. The evaluator must develop a plan of action (POA) that includes all required Areas of Operation and Tasks and administer each practical test in English. The POA must include scenario(s) that evaluate as many of the required Areas of Operation and Tasks as possible. As a scenario unfolds during the test, the evaluator will introduce problems and simulate emergencies that test the applicant’s ability. The evaluator has the discretion to modify the POA to accommodate unexpected situations as they arise or suspend and later resume a scenario to assess certain Tasks. Prior to and throughout the evaluation, the evaluator ensures the applicant meets the FAA Aviation English Language Standard (AELS). An applicant must be able to communicate in English in a discernible and understandable manner with air traffic control (ATC), pilots, and others involved in preparing an aircraft for flight and operating an aircraft in flight. This communication may or may not involve radio communications. An applicant for an FAA certificate or rating issued in accordance with 14 CFR parts 61, 63, 65, or 107 who cannot hear or speak due to a medical deficiency may be eligible for an FAA certificate with specific operational limitations. If the applicant’s ability to meet the FAA AELS comes into question before starting the practical test, the evaluator will not begin the practical test. An evaluator other than an ASI will check the box, “Referred to FSO for Aviation English Language Standard Determination,” located on the bottom of page 2 of the applicant’s FAA Form 8710-1, Airman Certificate and/ or Rating Application, or FAA Form 8710-11, Airman Certificate and/or Rating Application - Sport Pilot, as applicable. The evaluator will refer the applicant to the appropriate Flight Standards Office (FSO). If the applicant’s ability to meet the FAA AELS comes into question after the practical test begins, an evaluator who other than an ASI will discontinue the practical test and check the box, “Referred to FSO for Aviation English Language Standard Determination,” on the application. The evaluator will also issue FAA Form 8060-5, Notice of Disapproval of Application, with the comment “Does Not Demonstrate FAA AELS” in addition to any unsatisfactory Task(s). The evaluator will refer the applicant to the appropriate FSO. ASIs conducting the practical test may assess an applicant’s English language proficiency in accordance with FAA Order 8900.1. In either case, the evaluator must complete and submit the application file through normal application procedures and evaluators other than an ASI notify the appropriate FSO of the referral. If the ability of an FAA certificated airman comes into question prior to or during a required regulatory check (e.g., proficiency check) the evaluator other than an ASI will not continue the check or provide an endorsement indicating completion. The evaluator will refer the airman to the jurisdictional FAA field office for further determination of ability to meet the FAA AELS. For additional information, reference AC 60-28, FAA English Language Standard for an FAA Certificate issued under 14 CFR parts 61, 63, 65, and 107, as amended. Possible Outcomes of the Test A practical test has three possible outcomes: (1) Temporary Airman Certificate (satisfactory), (2) Notice of Disapproval of Application (unsatisfactory), or (3) Letter of Discontinuance. 62 Appendix 1: Practical Test Roles, Responsibilities, and OutcomesAirline Transport Pilot and Type Rating for Airplane Category ACS (FAA-S-ACS-11A) If the evaluator determines that a Task is incomplete, or the outcome is uncertain, the evaluator must require the applicant to repeat that Task, or portions of that Task. This provision does not mean that instruction, practice, or the repetition of an unsatisfactory Task is permitted during the practical test. Satisfactory Performance Refer to 14 CFR part 61, section 61.43, for satisfactory performance requirements. Satisfactory performance will result in the issuance of a temporary certificate. Depending upon the pilot flight crew complement required for the test, the pilot is expected to demonstrate competence in crew resource management in an operation or airplane certificated for more than one required pilot crewmember, or single- pilot competence in an operation or airplane that is certificated for single-pilot operations. If a successful check is conducted under an operator’s approved training and checking program, it is considered to have met the flight proficiency requirements of 14 CFR part 61, section 61.157(f) for the issuance of an ATP certificate and an appropriate rating. An evaluator that conducts ATP certificate evaluations in accordance with an approved 91K, part 121, or part 135 training and checking program is not required to use this document. Unsatisfactory Performance If, in the judgment of the evaluator, the applicant does not meet the standards for any Task, the applicant fails the Task and associated Area of Operation and the evaluator issues a Notice of Disapproval of Application. The evaluator lists the Area(s) of Operation in which the applicant did not meet the standard, any Area(s) of Operation not tested, and the number of practical test failures. The evaluator should also list the Tasks failed or Tasks not tested within any unsatisfactory or partially completed Area(s) of Operation. 14 CFR part 61, section 61.43(c)-(f) provides additional unsatisfactory performance requirements and parameters. Typical areas of unsatisfactory performance and grounds for disqualification include: • Any action or lack of action by the applicant that requires corrective intervention by the evaluator to maintain safe flight. • Failure to use proper and effective visual scanning techniques to clear the area before and while performing maneuvers. • Consistently exceeding tolerances stated in the skill elements of the Task. • Failure to take prompt corrective action when tolerances are exceeded. • Failure to exercise risk management. The evaluator or the applicant may end the test if the applicant fails a Task. The evaluator may continue the test only with the consent of the applicant. The applicant receives credit only for those Areas of Operation and the associated Tasks performed satisfactorily. Letter of Discontinuance Refer to 14 CFR part 61, section 61.43(e)(2) for conditions to issue a letter of discontinuance. If discontinuing a practical test for reasons other than unsatisfactory performance (e.g., equipment failure, weather, illness), the evaluator must return all test paperwork to the applicant. The evaluator must prepare, sign, and issue a Letter of Discontinuance that lists those Areas of Operation the applicant successfully completed and the time period remaining to complete the test to receive credit for previously completed Areas of Operation. The evaluator should advise the applicant to present the Letter of Discontinuance to the evaluator when the practical test resumes in order to receive credit for the items successfully completed. The Letter of Discontinuance becomes part of the applicant's certification file. Time Limit and Credit after a Discontinued Practical Test Refer to 14 CFR part 61, sections 61.39(f) and 61.43(f) after issuance of a Letter of Discontinuance or Notice of Disapproval of Application. 63 Appendix 1: Practical Test Roles, Responsibilities, and OutcomesAirline Transport Pilot and Type Rating for Airplane Category ACS (FAA-S-ACS-11A) ATP Certificate Task Table Each column title in the table below identifies the airplane category and class rating sought on the ATP certificate.
