I did landings two weeks ago after a couple of weeks of waiting. The cal sim was running and certified to use but the techs were working out a few visual issues. Used the 777b. I think the instructor issue may be a plausible cause. Heard all cal instructors will reinterview. Many are not happy with current situation thus leaving plenty of opportunity for ual 757 instructors to fill there spots. I could care less who shows up for the ride, just get me out early to make my flight home. Gotta love the politics of this industry.
