At our regional airline, all we carry is iPads which contain all of our charts, manuals, MELs, etc. We can not start a flight without 2, but can continue a flight when one malfunctions. They've had studies on the likelihood of both iPads failing and its very slim. Each Captain is also required to carry a backup battery. If both iPads were to fail, we are instructed to go through our ACARS and have dispatch send us the textual versions of the charts. We are told when and what to download on our iPad and can not use it for anything personal. We carry spares at each hub airport that our fully charged and updated, so that if this were to occur, then the flight wouldn't be delayed.
Tell that to all the pilots, flight attendants, mechanics, dispatchers, schedulers that work for those companies...theyre getting shorted on their paychecks!
Each regional contracted by their mainline partner is responsible for their own paperwork (fuel planning, weather, alternates, etc). Nothing is provided by mainline except the aircraft....
Compass....they are on a completely separate certificate with different dispatchers, pilots, F/As, etc. But its Trans States Holdings that will foot the bill.
