You will need an endorsement for the Commercial and Instrument writtens. However, none of the CFI or GI tests require a signoff. Remember that the Instrument, FII, and IGI all come from the same bank of questions, but they are different tests. So you would have to take all three, even though the questions are more or less the same. The BGI, AGI, and FIA all come from the same bank as the Commercial. The FOI is a completely different bank of questions.

Thanks to the King. I got it now. :D
Ok, I just need to find someone who'll endorse me. :confused:

BGI, AGI, and IGI are unnecessary if you are going to get a CFI (airplane) and CFII (instrument). A CFI certificate authorizes you to do ground instruction also. Anybody who tells you different just wants to charge 3 x $90 to take more written tests :rolleyes: The only use for a GI cert is for a non-pilot or non-cfi who has a job opportunity teaching groundschools (sometimes students who are working on the COMM/CFI may be able to make extra money teaching groundschools).

The FOI is necessary to get the CFI.

Rick's right, the GI's have no value unless you can get a job with it. That's why I got the AGI. But that's really the only one I'd get anyway, and it's fairly worthless. No matter what, passing the AGI doesn't make you a good ground instructor.

Aren't the GI/AGI's required to get a Gold Seal CFI or something of the sorts? I could get one, but don't really care

I think they are...but if you want to be an airline pilot it's not too relevant.
