If you read 121.513 it says “in place of the flight time limitations in 121.503 through 121.511 a certificate holder conducting supplemental operations may elect to comply with the flight time limitations of 121.515 and 121.521 through 121.525 for operations conducted (international blah blah)”
Then go to 121.523 Crew of three or more pilots and additional airmen AS REQUIRED
(C)”no certificate holder conducting supplemental operations may schedule any flight crew member to be on continuous duty for more than 30 hours.”
That as required part covers the fact that very few people fly with FEs or Navs anymore. It’s just a crew of 3 or more pilots.
