Understanding the Ground Instructor Certificate

The Ground Instructor Certificate is a Federal Aviation Administration (FAA) certification that allows individuals to teach aeronautical knowledge to students on the ground. Unlike a Certified Flight Instructor (CFI), CGIs do not conduct in-flight training; instead, they focus on theoretical training in classrooms or online settings. The CGI certificate has several categories, such as Basic Ground Instructor (BGI), Advanced Ground Instructor (AGI), and Instrument Ground Instructor (IGI), each tailored to different levels of instruction.

Ground Instructor License vs. Certificate

Many use the terms Ground Instructor License and Ground Instructor Certificate interchangeably, but the official terminology used by the FAA is "certificate." This certificate qualifies instructors to teach ground-based aviation knowledge but does not permit in-flight instruction. A CGI certificate is issued once candidates pass the required exams and meet the eligibility criteria.

Key Points:

Requirements to Become a Certified Ground Instructor

To become a CGI (Certified Ground Instructor), individuals must meet specific requirements set by the FAA. The requirements are less stringent than those for flight instructors, as no in-flight experience is required. Here’s a quick breakdown of the main eligibility criteria:

General Requirements:

For those pursuing the Instrument Ground Instructor (IGI) certificate, additional knowledge and testing in instrument flying rules are required.

Sample CGI - Certified Ground Instructor Practice Questions

Try these questions from our free CGI - Certified Ground Instructor practice tests. The correct answer and an explanation follow each question.

  1. How does the FAA ensure airspace safety?

    • A. By issuing flight delays
    • B. By offering flight deals
    • C. By managing air traffic and enforcing safety rules
    • D. By providing travel insurance

    Answer: C. By managing air traffic and enforcing safety rules

    The FAA ensures airspace safety primarily through its Air Traffic Organization (ATO), which controls air traffic movements across the nation. Additionally, it enforces strict safety regulations and standards for aircraft, pilots, and air carriers, minimizing risks and preventing accidents to maintain a safe flying environment.

  2. What is the standard lapse rate of temperature in the standard atmosphere?

    • A. 2°C per 1,000 feet
    • B. 3°C per 1,000 feet
    • C. 2°F per 1,000 feet
    • D. 4°C per 1,000 feet

    Answer: A. 2°C per 1,000 feet

    The standard lapse rate is approximately 2°C (3.5°F) per 1,000 feet of altitude increase in the troposphere.

  3. Which factor must be calculated for fuel planning?

    • A. Passenger weight only
    • B. Fuel price at destination
    • C. Trip and reserve fuel requirements
    • D. Aircraft paint color

    Answer: C. Trip and reserve fuel requirements

    Fuel planning is critical for flight safety and involves calculating the fuel needed for the intended trip, plus additional reserve fuel. Regulations mandate carrying enough fuel to fly to the destination, then to an alternate airport (if required), and then for a specified reserve period to account for unforeseen delays or diversions, ensuring a safe margin.

  4. Under 14 CFR 61.213, an Advanced Ground Instructor (AGI) is authorized to endorse applicants for which of the following knowledge tests?

    • A. Instrument rating only
    • B. Pilot certificates through the commercial pilot level
    • C. Airline transport pilot (ATP) certificate
    • D. Sport pilot only

    Answer: B. Pilot certificates through the commercial pilot level

    An AGI may endorse applicants for all knowledge tests through the commercial pilot certificate, including sport, recreational, private, and commercial.
