411a-
I'm going from memory here but I beleave the 100 ft DH is a requirement to meet lowwer than standard landing minimums under FAR 121. It is also requirement to have either 2 flight directors up and operating or 1 flight director and an opertive approach coupler on the auto pilot available. These do not need to be shown on a type ride but are required for a PC.
For the type ride (PTS) one approach must be hand flown but you can use the flight director and down to an altitude of 200 feet or a normal CAT1 minima.
If you had two pilots getting a type in the same airplane but one pilot operates the airplane under FAR 91 and the other under FAR 121 the type ride would be very simular except the 121 pilot could have a few maneuvers waived (like a circling approach).
Again, I'm going from memory, with out my referance material, I could be wrong.
