FAA A&P Practice Tests Compared: Sky License vs ASA vs Gleim

The FAA A&P Test Preparation Landscape

Preparing for the FAA A&P written tests is not straightforward. The three tests cover a vast range of topics — from electrical theory and aircraft drawings in General to complex turbine engine systems in Powerplant — and while the FAA publishes official handbooks, those are reference texts, not practice tools. Unlike pilot exams, where the prep ecosystem is mature, A&P candidates historically had fewer high-quality practice options.

Over the past decade, candidates have relied on a mix of study methods: the FAA handbooks (FAA-H-8083-30B, -31B, -32B), test prep books and software from publishers like ASA (Aviation Supplies & Academics), Gleim Aviation, and Jeppesen, plus free question collections shared between students. Each method has strengths, but none fully addresses the unique demands of the three FAA written tests — until now.

This guide provides an honest, detailed comparison of every major FAA A&P test preparation method available today. We evaluate each option on ten critical criteria: ACS alignment, question quality, adaptive learning, test simulation, mobile access, price, content currency, and more. By the end, you will have a clear understanding of which preparation method — or combination of methods — gives you the best chance of passing all three tests efficiently.

Feature Comparison Table

Detailed Comparison: Each Method Evaluated

1. Sky License — AI-Powered FAA A&P Test Platform

Sky License is a purpose-built FAA A&P test preparation platform designed specifically for the three FAA written tests. Unlike generic study tools that force aviation content into a one-size-fits-all template, Sky License is built from the ground up around the Aviation Mechanic ACS (AM.I, AM.II, AM.III).

Key strengths:

• AI-powered adaptive learning — The platform's core engine analyzes your performance on every question and adjusts difficulty in real time. If you consistently answer electrical questions correctly, the AI challenges you with harder scenario-based questions. If you struggle with turbine engine fuel systems, it serves more questions on that topic until you reach mastery. This targeted approach is far more efficient than linear study methods.
• Complete ACS coverage — Every question in Sky License is tagged to a specific ACS subject area. You can track exactly how much of the syllabus you have covered and identify gaps immediately.
• Detailed answer explanations — Each question includes a thorough explanation of why the correct answer is right and why each wrong answer is wrong, with references to the FAA handbooks and AC 43.13-1B.
• Timed practice test mode — Simulate the exact FAA test experience with time limits and question counts that match the real tests (60 questions/2h for General, 100 questions/2h for Airframe and Powerplant).
• Analytics dashboard — See your pass rate by test, by subject area, and over time. Identify your weakest areas at a glance and focus your study time where it has the most impact.

Best for: Candidates who want the most efficient, data-driven preparation across all three tests, with real-time progress tracking and AI-optimized study sessions.

2. ASA Prepware and Fast-Track — The Established Publisher

Aviation Supplies & Academics (ASA) is the best-known publisher of FAA test prep materials. Its Prepware software and apps cover the A&P tests, and its Fast-Track series — authored by the legendary Dale Crane — provides structured test guides that explain the "why" behind each answer. ASA also publishes the FAR/AMT regulations book and reprints of the FAA handbooks, making it a one-stop shop for print materials.

Strengths:

• Trusted question quality — ASA's questions closely mirror the FAA question bank, and their explanations are written by aviation maintenance educators.
• Timed practice tests — Prepware includes test-mode practice that simulates the real testing experience.
• Print + digital options — Fast-Track books are excellent for deep study away from a screen.

Limitations:

• No adaptive learning — Prepware presents questions in fixed order; it does not adjust to your performance or prioritize your weak areas.
• Separate products per test — You buy General, Airframe, and Powerplant prep separately, which adds up.
• Static explanations — No AI tutor to ask follow-up questions when an explanation is unclear.
• Edition lag — Print editions are updated on publisher cycles, so the newest ACS changes may not be reflected immediately.

Best for: Candidates who prefer established publishers, want physical books, and are comfortable managing three separate prep products.

3. Gleim Aviation — Structured Test Prep

Gleim Aviation produces a comprehensive A&P test prep suite: study units organized by subject area, an extensive question bank, and a test simulator. Gleim's approach is highly structured — the material is organized into study units with knowledge transfer outlines followed by question drills, which suits candidates who like a guided curriculum.

Strengths:

• Structured study units — Gleim's curriculum-style organization tells you what to study in what order.
• Large question bank — Thousands of questions across all three tests.
• Test simulator — Gleim's software replicates the computer-based testing environment.

Limitations:

• No adaptive difficulty — Like ASA, Gleim does not use AI to adapt question difficulty to your performance.
• Desktop-centric — Gleim's software is historically desktop-oriented; mobile experience is less polished than modern web platforms.
• Separate purchases — General, Airframe, and Powerplant prep are sold as separate products.
• No AI tutor — Explanations are static; there is no conversational way to clarify confusing topics.

Best for: Candidates who want a rigid, curriculum-style study structure and are comfortable with desktop software.

4. Jeppesen — Textbook-Style Training

Jeppesen's A&P Technician series is a set of comprehensive textbooks (General, Airframe, Powerplant) used by many Part 147 schools. The books are excellent for building deep theoretical understanding and are often required reading in AMT programs.

Limitations:

• Reference material, not practice tool — The Jeppesen books teach concepts but provide limited exam-style question practice.
• Dated content in places — Some chapters lag behind the latest technology and ACS updates.
• No adaptive features or analytics — Books cannot track your readiness or target your weak areas.

Best for: Building foundational understanding as a complement to a practice-focused platform like Sky License.

5. Generic Quiz Apps (Quizlet, Kahoot, etc.)

General-purpose quiz apps are appealing because they are free or low-cost and available on mobile. Some A&P candidates use them to create simple multiple-choice quizzes from their notes.

Limitations:

• Not designed for FAA tests — These platforms are built for general education. They lack the question formats, figure-based questions, and technical depth that the FAA tests require.
• No ACS alignment — There is no mechanism to ensure your practice covers all subject areas. You could easily miss entire topics without realizing it.
• Minimal or no explanations — Even when answers are provided, generic quiz apps rarely include detailed explanations. This means you are not learning from your mistakes — you are just measuring them.
• No test simulation — These apps are not designed to replicate the pressure, timing, or format of the FAA knowledge tests.

Best for: Quick, casual review of simple facts on mobile. Not recommended as a primary preparation method.

6. Old Question Banks / Free PDF Collections

Word-of-mouth sharing of "old exam questions" has been a staple of A&P preparation for decades. Students compile questions they remember from their tests and share them in PDF format or through online forums.

Limitations:

• Outdated and inaccurate — The FAA updates its test question bank regularly. A PDF from even two years ago may contain questions based on outdated material. Relying on old material can lead to confidently wrong answers on test day.
• No quality control — Remembered questions are notoriously unreliable. Candidates often misremember details, and answers shared online are frequently incorrect — yet spread as "verified" through repetition. Every Sky License question, by contrast, is authored and reviewed by aviation maintenance subject-matter experts.
• Static format — PDFs cannot adapt to your performance, simulate timed conditions, or provide interactive feedback.
• No coverage tracking — PDF collections are rarely organized by ACS subject area, so you cannot systematically track what you have covered.

Best for: Supplemental browsing only. Not recommended as a primary or even secondary preparation method for serious candidates.
