), the applicant should be prepared for questions on any weather product presented in the references for that Task. 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. Combined Private/Instrument Test Applicants for a combined Private Pilot Certificate with Instrument Rating, in accordance with 14 CFR part 61, section 61.65(a) and (g), must pass all areas designated in the Private Pilot for Airplane ACS and the Instrument Rating – Airplane ACS. Evaluators need not duplicate Tasks. For example, only one preflight demonstration would be required; however, the Preflight Task from the Instrument Rating – Airplane ACS would be more extensive than the Preflight Task from the Private Pilot for Airplane ACS to ensure readiness for Instrument Flight Rules (IFR) flight. Applicants for a combined test must present the applicable test reports. A combined certificate and rating evaluation should be treated as one practical test, requiring only one application and resulting in only one temporary certificate, disapproval notice, or letter of discontinuance, as applicable. Failure of any Task will result in a failure of the entire test and application. Therefore, even if the deficient maneuver was instrument related and the performance of all visual flight rules (VFR) Tasks was determined to be satisfactory, the applicant will receive a notice of disapproval. 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 Private Pilot for Airplane Category ACS (FAA-S-ACS-6C)68 Appendix 1: Practical Test Roles, Responsibilities, and Outcomes • 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.

The abbreviation(s) within parentheses immediately following a Task refers to the category and/or class airplane appropriate to that Task. The absence of a class indicates the Task is for all classes. The meaning of each abbreviation is as follows: • ASEL—Airplane – Single-Engine Land • ASES—Airplane – Single-Engine Sea • AMEL—Airplane – Multiengine Land • AMES—Airplane – Multiengine Sea ote:N
