Both the MD11s and A300s at FedEx are two pilot aircraft. FedEx types all F/Os on the MD11. They do not type any F/Os on the A300. A good prtion of the time I fly with just a F/O, my last trip MEM-ANC, ANC-NRT, NRT-SFS-HKG all with two pilots, the remainder, HKG-ALA, ALA-CDG, CDG-MEM all with a RFO. The first of those actually did not require the RFO but we carry one. Now the A300 fleet are actually A300-600s, or A310s. No A300 F/Os are type rated normally, although there may be a few that work or worked in training that have the rating. The A300 flys all over Asia, and all over Europe and the Middle East with F/Os that are not type rated. They are trained to FAA F/O standards which is really no different than the MD11 type rated F/Os.
The deal is that there must be ONE type rated pilot on the flight deck at all times. If the block time exceeds 8 hours the Captain cannot be scheduled to to be in the cockpit in excess of 8 hours. FedEx could have decided to type rate only a portion of the MD11 F/Os and use them as just relief pilots. They have chosen to rate all because it makes scheduling a lot easier. Any F/O can be either a F/O or RFO, and any Captain can be a RFO.
