ACS Written Test codes for Instrument Pilot FAA Written Test Results

Below are the ACS codes (formerly known as PLT codes) that you will find on your FAA written test results. If you missed any questions on your Instrument FAA written exam (most people do!) you will have a few of these codes listed on your computer test report.

While the FAA dosen’t tell us exactly which questions we missed, they do give us the ACS question codes that are directly associated with the subject area we missed question(s) in.

You can use your browser’s find function to look up ACS error codes in the table below, and click on the subject to the right of that error code to review content associated with that subject.
