About the FAA Flight Engineer Exam
The FAA Flight Engineer Knowledge Test is the airman knowledge test required under 14 CFR Part 63 Subpart B for the flight engineer certificate. It is class-specific: FEX for turbojet-powered aircraft, FET for turboprop-powered, and FEN for reciprocating-powered. The basic test is 80 multiple-choice questions covering regulations, aircraft systems, powerplants, performance and weight-and-balance, meteorology, systems monitoring, and emergency procedures.

Frequently Asked Questions
How many questions are on the FAA Flight Engineer knowledge test?
The FAA flight engineer basic knowledge test has 80 multiple-choice questions. An added class-rating test, taken when an applicant already holds a flight engineer certificate in another class, is shorter at 50 questions. This free practice bank provides 100 selected-response items spanning the basics.
What are the FEX, FET, and FEN test codes?
The flight engineer knowledge test is class-specific. FEX is the turbojet-powered class test, FET is the turboprop-powered class test, and FEN is the reciprocating-powered class test. You take the test that matches the class of aircraft for which you are seeking a flight engineer rating.
What score do I need to pass, and how long is the test?
You must score at least 70% to pass the FAA flight engineer knowledge test. You are allotted 3 hours to complete the 80-question basic test, which is administered by computer through PSI testing centers.
What are the eligibility requirements under 14 CFR Part 63?
Under 14 CFR Part 63 Subpart B, a flight engineer applicant must be at least 18 years old and able to read, speak, write, and understand English, and must meet the aeronautical experience requirements. To exercise flight engineer privileges, you must hold at least a second-class FAA medical certificate.
Is the flight engineer certificate still offered in 2026?
Yes. The FAA still issues the flight engineer certificate and administers the FEX, FET, and FEN knowledge tests through PSI under 14 CFR Part 63. While most modern transports use two-pilot crews, the certificate remains valid for aircraft and operations that require a flight engineer.
