AMES Requirements 2026: Eligibility, Prerequisites & How to Qualify

What AMES Actually Is: A Class Rating, Not a Written Exam

In this article, AMES means the FAA's Airplane - Multiengine Sea rating, the class rating that lets a pilot operate multiengine seaplanes. It is issued by the Federal Aviation Administration. If you arrived here expecting a seat at a testing center, a fixed question count and a percentage cut score, it helps to reset expectations early: none of that applies to this rating.

AMES is an additional class rating. You earn it by training with a qualified instructor, receiving the required endorsement, and passing a practical test, an oral/ground evaluation plus a flight evaluation, with an authorized FAA evaluator, commonly a designated pilot examiner. There is no distinct AMES knowledge-test appointment, and the reviewed FAA sources publish no AMES-specific question count, timer, pass percentage or pass-rate figure. If you want background on the terminology first, see our explainers on what AMES is and what AMES stands for.

Who Can Add It: Certificate Level and Ratings Held

AMES is not a stand-alone certificate. It is added to a pilot certificate you already hold, so the first eligibility question is always: which certificate and which ratings do you have today? The practical test you take depends on that answer. The FAA publishes separate Airman Certification Standards (ACS) for the certificate levels:

• Private Pilot, Airplane Category: ACS FAA-S-ACS-6C
• Commercial Pilot, Airplane Category: ACS FAA-S-ACS-7B
• Airline Transport Pilot, Airplane Category: ACS FAA-S-ACS-11A

The two non-ATP documents are dated November 2023, were published by the FAA in April 2024 and became effective May 31, 2024. Each contains an additional-rating task table for AMES, printed on page 73 of the respective PDF.

A caution about school entry requirements

You will see flight schools state their own entry rules. One school's published materials, for example, are inconsistent about whether a private or commercial certificate is expected. Treat provider-specific entry statements as that provider's policy, not as a universal FAA prerequisite. Ask any school you are considering exactly which certificate level they require and why, and confirm against the applicable ACS and 14 CFR Part 61.

The Regulatory Path Under 14 CFR 61.63(c)

For an additional class rating below ATP, the governing rule is 14 CFR 61.63(c). In plain terms, the path has two required pieces:

1. An instructor endorsement attesting to your knowledge and proficiency for the class rating you are adding.
2. A practical test with an authorized evaluator.

Notably, this regulation does not prescribe a fixed additional training-hour minimum for adding this airplane class. That surprises candidates who assume a mandatory number of hours. The practical consequence is that your instructor decides, based on demonstrated performance, when you are ready to be endorsed. Some pilots finish quickly; others need more dual time, especially if water handling is new to them.

The written-test waiver is conditional

The additional knowledge-test waiver applies only when you already hold a listed aircraft rating at the relevant certificate level. Do not generalize it. It does not automatically extend to every initial pilot-certificate applicant or to ATP candidates. If you are unsure whether the waiver covers your situation, have your instructor or evaluator confirm it before you build a schedule around it.

How Your Existing Ratings Change the Checkride

This is the part most candidates overlook. The AMES additional-rating task tables in the Private and Commercial ACS make required tasks conditional on ratings you already hold. An existing AMEL (Airplane Multiengine Land) rating is treated differently from ASEL (Airplane Single-Engine Land) or ASES (Airplane Single-Engine Sea). The tables are not interchangeable, and the task credit you receive depends on your starting point.

Treat the table above as orientation, not a substitute for the ACS. Your evaluator will use the applicable task table in the ACS for your certificate level and held ratings, so read that table, printed on page 73 of each document, before you train.

ATP-Level AMES Is Governed Separately

If you are pursuing AMES at the airline transport pilot level, the standard is FAA-S-ACS-11A, together with 14 CFR 61.165. This is a distinct framework. Do not assume that the task credit described for private and commercial applicants applies to ATP. If you hold or are pursuing an ATP certificate, work from the ATP ACS and confirm requirements directly with your evaluator rather than extrapolating from the lower-level tables.

The Seven Preparation Areas You Must Master

Our preparation index organizes AMES study into seven areas. To be clear about what this is: it is an unweighted preparation index, not seven official exam domains and not an exhaustive checkride syllabus. No percentage weights are published. The content draws on the FAA's Seaplane, Skiplane, and Float/Ski Equipped Helicopter Operations Handbook (FAA-H-8083-23, 2004 edition, still linked by the FAA), using chapters 1-6 and 8. Chapter 7 covers skiplanes and chapter 9 covers helicopters, and neither belongs in AMES preparation. For a deeper walkthrough, see our complete guide to all seven content areas.

What the Practical Test Looks Like

Expect an oral/ground portion followed by a flight portion. The evaluator works from the ACS tasks that apply to your certificate level and held ratings. Across the Private and Commercial tables, AMES-tagged objectives include:

• Water and Seaplane Characteristics, Seaplane Bases, Maritime Rules, and Aids to Marine Navigation
• Taxiing and Sailing
• Confined Area Takeoff and Maximum Performance Climb
• Confined Area Approach and Landing
• Glassy Water Takeoff and Climb, and Glassy Water Approach and Landing
• Rough Water Takeoff and Climb, and Rough Water Approach and Landing
• Seaplane Post-Landing Procedures

Depending on which table applies to you, additional required work may include performance and limitations, systems, preflight, normal takeoffs and landings, steep turns, slow flight and stalls, simulated engine failures, one-engine-inoperative maneuvering and VMC demonstration.

Aircraft flight-manual limitations and the appropriate checklists govern throughout. Because this is a flight evaluation rather than a written test, there is no universal open-book, calculator or remote-proctoring policy to describe. If you want a data-driven view of outcomes, note that no AMES-specific pass rate is published in the reviewed FAA sources, so our pass-rate page explains what can and cannot be said.

What Training Packages Cost: Provider Examples

No nationwide FAA fee schedule for AMES training or the checkride was verified, and there is no member/non-member pricing. What exists are individual provider packages. The two examples below are illustrations of what some schools display, not national averages and not FAA minimum hours:

When you compare packages, check what is included (aircraft rental, fuel, ground instruction, evaluator fee), whether taxes are extra, and what happens if you need additional dual time. For a fuller discussion, see our AMES certification cost breakdown.

Keeping the Privilege: Currency, Not Renewal

Under 14 CFR 61.19, pilot certificates normally have no expiration date, subject to suspension, revocation, surrender and applicable limitations. AMES is therefore not a biennial CEU-renewal credential. There is no renewal fee cycle attached to the rating itself.

What does apply are the ordinary privileges-and-currency rules:

• Flight review (14 CFR 61.56): generally based on 24 calendar months, with provisions allowing practical-test credit.
• Passenger carrying (14 CFR 61.57): generally three takeoffs and landings within 90 days in the same category and class, with additional night conditions and exceptions.
• Medical qualification: required as applicable to the privileges you exercise.

Because the 90-day passenger rule is category-and-class specific, staying current in a multiengine sea airplane means flying one, which can be a real constraint if you live far from water or rely on rental availability.

Sequencing Your Preparation

Rather than a generic study plan, sequence your preparation around the order in which AMES skills build on each other. Schedule ground topics before the flights that depend on them, and do the water-specific domains early because they are the unfamiliar part for most land pilots.

Your actual calendar will depend on instructor and aircraft availability and on how much credit your held ratings provide.
