Don't know the specifics of the FBC, but it depends upon their definition of an Attic.
What should be the requirement is that the air handler is placed within the building thermal envelope. So if the air handler is above a ceiling, but the building insulation is at the roof deck, the air handler is within the building thermal envelope, even if the above ceiling area is pitched, has trusses and ceiling rafters, and othewise looks like what normal people call an "attic". this is no different than an air handler above a lay in ceiling in a metal joist building with an insulated steel roof.
Building a room with all walls and ceiling insulated but no insulation on the floor would also put the air handler within the thermal envelope.
