Ground instructor training v. ground instructor signoffs
highflying said:
If I take the test and get the AGI doesnt that mean I can also teach instruments students, so then I dont need to take the IGI do I?
You can hold anything you want to hold to teach instrument ground and sim. You have to hold the appropriate ground instructor ratings in order to sign off your students for writtens.
You have to read through
14 CFR 61.215 in its entirety to understand the privileges given under each ground instructor rating. In particular, 14 CFR 61.215(d) provides clarification:
Sec. 61.215 - Ground instructor privileges.
(a) A person who holds a basic ground instructor rating is authorized to provide:
(1) Ground training in the aeronautical knowledge areas required for the issuance of a recreational pilot certificate, private pilot certificate, or associated ratings under this part;
(2) Ground training required for a recreational pilot and private pilot flight review; and
(3) A recommendation for a knowledge test required for the issuance of a recreational pilot certificate or private pilot certificate under this part.
(b) A person who holds an advanced ground instructor rating is authorized to provide:
(1) Ground training in the aeronautical knowledge areas required for the issuance of any certificate or rating under this part;
(2) Ground training required for any flight review; and
(3) A recommendation for a knowledge test required for the issuance of any certificate under this part.
(c) A person who holds an instrument ground instructor rating is authorized to provide:
(1) Ground training in the aeronautical knowledge areas required for the issuance of an instrument rating under this part;
(2) Ground training required for an instrument proficiency check; and
(3) A recommendation for a knowledge test required for the issuance of an instrument rating under this part.
(d) A person who holds a ground instructor certificate is authorized,
within the limitations of the ratings on the ground instructor certificate, to endorse the logbook or other training record of a person to whom the holder has provided the training or recommendation specified in paragraphs (a) through (c) of this section.
(emphasis added)
So, perhaps any ground instructor can provide any kind of instruction. But it takes an appropriately-rated ground instructor to provide the signoff.
Hope that helps a little.
PS-If you hold a Basic Ground Instructor certificate and take and pass the Instrument Ground Instructor written, you will be issued a Ground Instructor certificate with Advanced and Instrument ratings upon presentation of your written test report and 8710 to the FAA. You will not have to take the AGI written.
