If you are taking the ride with an FAA guy they will most certainly cover all the FOI stuff, if you are hiring a DPE then its kinda 50/50 if they will cover FOI. some look at the ground cert and skip it, some might ask an easy gimme question or two, and some will cover all of it as stated by the PTS. having the ground cert doesn't skip it in the PTS but some DPEs look at it that way because the regs say the FOI endorsement and test is not required for the eligibility.
