PLT399: Display of Certificates
What code PLT399 covers, why the FAA tests it, and how to study Display of Certificates before your checkride.
Recall regulations - display / inspection of licenses and certificates
What this means for your checkride
To act as pilot in command or a required crewmember you must have your pilot certificate, an appropriate photo identification, and, unless exercising privileges that do not require one, a valid medical certificate, in your physical possession or readily accessible in the aircraft. You must present them for inspection on request by the FAA, NTSB, or law enforcement.
Carrying and presenting the required certificates is a basic legal duty, so the FAA tests what you must have and to whom you must show it.
Pilots leave the certificate at home when they know the airplane. You must have the pilot and medical certificates and a photo ID accessible on every flight and present them on request.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
