FAA Written Test Codes Lookup: PLT, ACS, or exam code?

As of July 18, 2026, this lookup covers all 527 FAA PLT learning statements, from PLT001 through PLT527. Current ACS-aligned tests can print an ACS element code instead, while PAR, IRA, CAX, and UAG identify the exam itself. Start by separating those three code families.

Code Triage

Three FAA code families that look deceptively similar

The fastest lookup is the correct lookup. Use the shape of the printed code to decide whether you need a test matrix, the PLT index, or the current ACS.

FAA PLT Code Lookup

Search the complete PLT001–PLT527 index

The index preserves all 527 entries in the FAA guide, including codes the FAA labels deleted, so an older unexpired report remains traceable. Descriptions identify the weak subject; they do not reproduce the missed question.

Enter the exact code printed on an older AKTR, or search the FAA description by topic.

Common private-pilot examples
  • PLT005

    Calculate aircraft performance - density altitude

AKTR Remediation

What to do after the code lookup

  1. 1

    Keep the original AKTR

    The FAA companion guide tells applicants to retain the report. It carries the score, test identity, and every reported deficiency code.

  2. 2

    Identify the code family

    A three-letter exam code such as PAR is not a missed-topic code. PLT### is a learning statement; an ACS code points into an ACS Area of Operation, Task, and element.

  3. 3

    Translate the deficiency

    Search a PLT code below or open the correct ACS revision. Write down the actual subject instead of memorizing the code label.

  4. 4

    Review the governing source

    Study the relevant handbook, FAR/AIM section, chart, or testing supplement and practice applying it in a scenario.

  5. 5

    Close the loop with an instructor

    Use the code list as a diagnosis, not a syllabus. Your instructor should verify the weak area and complete any required retraining or endorsement.

FAA Written Test Codes FAQ
Q1Where can I look up FAA written test codes?
First identify the code type. Search PLT learning-statement codes in the 527-entry FAA index on this page. For a code such as PA.I.A.K1, use the Airman Certification Standards revision effective on the test date. For PAR, IRA, CAX, or UAG, use the FAA testing matrix because those are exam codes, not missed-topic codes.
Q2What does a PLT code mean on an AKTR?
PLT followed by three digits identifies an FAA learning statement associated with a question answered incorrectly. The statement names the deficient subject area; it does not reveal the original test question or provide a complete training syllabus.
Q3Why does my FAA written test report show an ACS code instead of PLT?
The FAA companion guide explains that knowledge tests use ACS element codes after an ACS becomes the effective standard for that certificate or rating. Older valid reports can still contain PLT codes during the transition, so both lookup paths remain relevant.
Q4Is PAR an FAA deficiency code?
No. PAR identifies the Private Pilot Airplane knowledge test. A deficiency code appears on the Airman Knowledge Test Report after the exam and is formatted as a PLT learning-statement code or an ACS element code, depending on the applicable testing standard.
Q5What should I do after I look up a missed FAA code?
Translate the code into the tested subject, review the current governing source, practice applying the concept, and ask an instructor to verify the deficiency is corrected. Keep the original report for retest or practical-test requirements.

Turn the code into a study decision

Use the code to name the weak subject, then work from the current ACS and FAA source material. GroundScholar's practice routes keep the exam, checkride standard, and remediation path connected.
