PSI is currently the provider of over 60 different FAA Exam certification tests and is one of two providers that the FAA has chosen to deliver a variety of exams related to aircraft operation and maintenance.
The most important of them is probably the FAA Airman exam, also known as the FAA Airman Knowledge Test. This test exists in different variations depending on the specific type of aircraft you want to be licensed for, such as the Sport Pilot, Recreational Pilot, Remote (Drone) Pilot, Private Pilot, and Commercial Pilot tests.
The FAA Airman Knowledge Test is composed of multiple-choice questions that are related to proficiency and rules covering the aircraft you are being licensed for. FAA regulations allow candidates to bring a protractor, plotter, calculator (not a scientific calculator), and an E6B flight computer (manual or electronic) if needed. Pens, pencils, and scratch paper cannot be brought into the exam center but will be provided to you.
