Ground Instructor is a certificate issued in the United States by the Federal Aviation Administration (FAA).
There are three classes of holder, licensed to provide the ground instruction element in the training of three groups: Ground Instructor is a certificate issued in the United States by the Federal Aviation Administration; the rules for certification, and for certificate-holders, are detailed in Subpart I of Part 61 of the Federal Aviation Regulations, which are part of Title 14 of the Code of Federal Regulations.
Ground Instructor certificates are issued with ratings, and these determine the exact areas in which the holder may give instruction.
[4] This is a written exam similar to, but showing a higher knowledge, of aviation than those required for a private or commercial airplane license, or an instrument rating.
To be eligible to give instruction, though, the holder must have either served as an instructor in the preceding twelve months or have received from a ground or flight instructor an endorsement certifying the holder's proficiency in the subject matter which the certificate authorizes teaching.
