- GPC here means GEOINT Professional Certification Aeronautical, specifically Aeronautical Analysis Proficiency Level II (AA-II), issued by NGA.
- AA-II has 110 questions, a 150-minute limit, and is paper-based, delivered in English at authorized government sites.
- Safety of Navigation and Production each carry 25% of the blueprint, making them half the exam together.
- Candidates need valid GPC-F, three years of aeronautical analytic experience, and an active clearance to qualify.
What GPC Means on This Site
The acronym "GPC" is shared by several unrelated credentials, which causes real confusion for anyone searching the term. On this site, GPC refers to exactly one thing: the GEOINT Professional Certification for Aeronautical Analysis, specifically Aeronautical Analysis, Proficiency Level II (AA-II). It is a government-run professional certification for geospatial intelligence practitioners who work with aeronautical data, products and navigation safety.
If you landed here looking for a different credential that happens to abbreviate to GPC, the details below will not apply to you. For a quick orientation on the naming question, see our explainers on what GPC stands for and what GPC certification is. This article is the broad overview: who runs the program, who qualifies, what the assessment looks like, and what the credential signals to employers.
Who Issues and Administers It
The certification is issued by the National Geospatial-Intelligence Agency (NGA). Some third-party catalog metadata labels the issuer differently, but the issuer's own public documents consistently use NGA, and that is the name to rely on.
Day-to-day administration runs through the NGA GPC Program Management Office, working with authorized assessment sites and approved GPC proctors at government facilities. This is a significant difference from commercial certifications: there is no open storefront where anyone can buy a seat. The assessment is free for eligible candidates, but access is gated by role, experience and clearance rather than by willingness to pay.
Passing is determined against a score approved by the program's Governance Council. We were not able to verify a current numeric AA-II passing score or a published pass rate in public sources, so any site quoting a precise cut score or percentage should be treated skeptically. Our coverage of that gap is in GPC Passing Score 2026 and GPC Pass Rate 2026: What the Data Shows.
Where AA-II Sits in the GEOINT Certification Ladder
The GEOINT Professional Certification program is tiered. The foundational credential, GPC-F, is the entry point and is a hard prerequisite for AA-II. AA-II is the proficiency-level credential for aeronautical analysts who have moved beyond foundational knowledge into full-performance tradecraft.
| Element | GPC-F (Foundation) | AA-II (Aeronautical Proficiency Level II) |
|---|---|---|
| Role in program | Foundational prerequisite | Aeronautical specialty proficiency credential |
| Prerequisite | General program eligibility | Valid GPC-F plus aeronautical experience |
| Experience emphasis | At least one year of GEOINT experience in a DoD work role | At least three total years of GEOINT aeronautical analytic experience |
| Renewal | Three-year cycle with professional development units | Expires and renews together with GPC-F |
One practical consequence: AA-II does not run on its own independent clock. If GPC-F lapses, AA-II goes with it. Candidates sometimes assume each credential has a separate three-year cycle; it does not.
Eligibility: Who Can Actually Sit the Assessment
This is where GPC differs most from open-enrollment certifications. Eligibility is built around government workforce status. General requirements include:
- An active GEOINT-related role within the National System for Geospatial Intelligence
- At least one year of GEOINT experience in a Department of Defense work role
- An active U.S. Government or Commonwealth Partner-equivalent clearance appropriate to the assessment classification
- Good standing with your employing agency or component
AA-II layers on specific requirements: a valid GPC-F certification, at least three total years of GEOINT aeronautical analytic experience, and full-performance Aeronautical Analysis tradecraft entry qualifications, demonstrated through a relevant diploma, degree or certificate and/or prior professional experience.
No specific commercial training course, association membership or product purchase is mandatory. That matters for anyone being pitched "required" prep packages. The full breakdown lives in GPC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Assessment Format and Rules
The AA-II assessment has 110 questions and a 150-minute time limit. It is paper-based and delivered in English. That works out to a little under 1.4 minutes per question on average, which is workable for knowledge items but leaves little room to dwell on any single one.
At the program level, objectively scored item types include multiple-choice, true/false, matching and fill-in-the-blank. The program-level list does not establish the exact item-type mix for AA-II specifically, so do not assume a particular proportion of each.
Test-day logistics
- Advance registration is required.
- Valid government-issued photo identification is required.
- Proctors supply assessment materials. You do not bring your own.
- Personal electronics are prohibited in the testing area.
- Sessions are held at authorized assessment sites with approved GPC proctors at government facilities.

The Six Competency Areas and Their Weights
The AA-II blueprint is organized into six formal examination core competencies, and the weights total 100%. These come from NGA's published Essential Body of Knowledge for AA-II and are confirmed in the program handbook. They are exam competencies, not a recommended curriculum order.
| Domain | Name | Weight |
|---|---|---|
| 1 | Safety of Navigation: Aeronautical Governance and Industry | 25% |
| 2 | Customer Requirements: Aeronautical Source | 15% |
| 3 | Production: Aeronautical GEOINT Production | 25% |
| 4 | Quality Assurance: Aeronautical Quality | 13% |
| 5 | Data Processing: Aeronautical Data | 10% |
| 6 | Customer Operations: Aeronautical Customer Service and Data/Product Access | 12% |
Safety of Navigation and Production are jointly the largest at 25% each, so half of the blueprint rests on just two competencies. A deeper walk through each is in GPC Exam Domains 2026: Complete Guide to All 6 Content Areas.
Concrete Topics Aeronautical Analysts Must Master
The competency names point to the kind of knowledge the assessment rewards. Here is how to think about each area in practical, analyst-facing terms, working from the public objectives rather than any controlled content.
Domain 1: Safety of Navigation: Aeronautical Governance and Industry (25%)
This is the governance backbone of aeronautical work: how aeronautical information is regulated, standardized and shared across government and industry.
- Roles of governing bodies and standards that shape aeronautical data and products
- How industry practice and government policy intersect in flight-safety information
- Why accuracy and timeliness are safety issues, not just quality preferences
Domain 2: Customer Requirements: Aeronautical Source (15%)
Analysts must translate what a customer needs into the right sources and data.
- Identifying and evaluating aeronautical source material
- Matching source characteristics to mission or customer requirements
- Recognizing source limitations before they propagate into products
Domain 3: Production: Aeronautical GEOINT Production (25%)
The other half of the heavy weighting. This covers building aeronautical GEOINT products to specification.
- Production workflows and tradecraft for aeronautical products
- Applying standards and specifications during compilation
- Understanding how production decisions affect downstream users
Domain 4: Quality Assurance: Aeronautical Quality (13%)
Quality is a verification discipline, not an afterthought.
- Methods for validating aeronautical data and products against requirements
- Recognizing and categorizing errors and discrepancies
- Feedback loops that correct problems at the source
Domain 5: Data Processing: Aeronautical Data (10%)
The smallest domain by weight, but foundational to everything else.
- How aeronautical data is ingested, structured and maintained
- Data handling practices that preserve integrity through processing
Domain 6: Customer Operations: Aeronautical Customer Service and Data/Product Access (12%)
Delivering products and supporting the people who use them.
- Getting the right data and products to the right customer
- Customer support practices and access mechanisms
- Responding to customer questions and feedback in an operational setting
A cheat-sheet style recap of these areas is in GPC Cheat Sheet 2026: One-Page Review of Must-Know Facts, and the broader prep approach is in the GPC Study Guide 2026.
Cost, Registration and Retake Mechanics
The assessment is free for eligible candidates. Unlike many certifications, there is no public exam fee to budget for, because the program is delivered through government channels rather than sold commercially. Costs that do exist tend to be indirect: your time, any optional study resources you choose to buy, and travel if your site is not co-located with your workplace. See GPC Certification Cost 2026: Complete Pricing Breakdown for the full picture.
Registration is done in advance through the program's administrative channels, and you will need valid government-issued photo ID on test day.
If you do not pass
Retaking the same assessment after a failure requires a 90-calendar-day wait after each exposure, and that applies even if you did not complete the assessment. Treat each attempt as a real one: sitting down underprepared still starts the clock.
Key Takeaway
Because every exposure triggers a 90-day wait, schedule your attempt only after you can consistently perform across all six competencies, not just the two 25% heavyweights. A strong showing in Safety of Navigation and Production can still be undone by neglecting the 38% that sits in the remaining four areas combined with Quality Assurance, Customer Requirements, Customer Operations and Data Processing.
Keeping the Credential Active
AA-II does not carry its own independent three-year cycle. It expires and renews with GPC-F. To maintain all the GPC credentials you hold, you need:
- 100 professional development units earned during the three-year GPC-F cycle
- Good standing
- The required submission through the Certification Management System
Plan renewal activity from the start of the cycle rather than the end. Professional development units accumulate naturally through training, professional activity and continued tradecraft work, but only if you track them.
Who Benefits and Where Careers Go
Because eligibility is tied to the National System for Geospatial Intelligence and DoD work roles, the people who hold AA-II are overwhelmingly government and government-adjacent GEOINT professionals working aeronautical analysis. The credential signals documented, assessed full-performance competence in aeronautical tradecraft, which is valuable for internal advancement, specialized assignments and credibility with customers who depend on safe, accurate aeronautical information.
We do not publish invented salary numbers here. Earnings depend heavily on grade, clearance, location and employer, and no verified AA-II-specific salary dataset exists in the sources we checked. For a qualitative treatment of how the credential figures into compensation and advancement, see GPC Salary Guide 2026, Is the GPC Certification Worth It? and GPC Jobs.
Preparing Without Controlled Content
The AA-II handbook marks the assessment U//FOUO, and actual assessment content is controlled and not authorized for public release or personal use. That has a direct implication for study: legitimate preparation relies on public objectives and original practice material, not leaked or reconstructed exam questions. Any resource claiming to reproduce real test items should be avoided, both for integrity reasons and because possessing controlled content can jeopardize your standing.
Likewise, do not accept GPC-F question banks marketed as AA-II coverage. The two assessments serve different purposes, and foundation-level practice does not map onto aeronautical proficiency content.
A domain-weighted study sequence
If you build a schedule at all, let the blueprint drive it. One reasonable sequencing, tied to the weights above:
Safety of Navigation
- Governance and industry context: the largest single block at 25%
- Build the vocabulary that the other domains assume
Production
- Aeronautical GEOINT production tradecraft: the other 25%
- Connect production decisions to the safety context from the prior weeks
Source, Quality, Data and Customer Operations
- Cover the remaining four competencies (15%, 13%, 10%, 12%)
- Use original practice questions to find weak spots across all six areas
You can test yourself against original, non-controlled practice material on the main practice test site, and the GPC practice exams there are designed around the public competency structure rather than any controlled assessment content.
