Furthermore, if you are doing a sim course on the Lear by a FAA certified training facility, you might as well just do the Comm /ATP checkride as well. It is at no extra expense, and will require you to write just one exam. IMHO the Lear really does require a sim course, and the FAA require you to have at least a Co-Jo rating endorsed on your license, to fly in it as a required crew member.
