Again, it depends. Normally a level B requires you to perform some maneuvers in the aircraft but, depending on the applicant's qualifications, there can be waivers to that requirement. And it has to be done in accordance with the training center's approved program. The only -6 sim I see on the FAA list is operated by FSI. They may have more restrictive requirements than the regulations. Or they may have authorization to do stuff not normally allowed by the regs. You need to talk to the training center.
