Not an automated system, but I believe cabin crew check in with cockpit at least every 30 minutes? If they don’t respond, cabin crew can enter the cockpit (if no response to cockpit door “bell”)
Never heard of that. Maybe on some of those EK longhaul flights with tired skeleton crews?
This thread can only be summarized as a rabbit hole of unfounded assumptions. Maybe we should rephrase the discussion as "what do pilots do in cruise when workload is lower? " or "how does automation in the E170/190 ease pilot workload compared to other jets?".
First, pilots mostly pass the time visiting with each other. Imagine you're going on a road trip with someone from your work... you're going to make small talk at a minimum. It's different in nature than sitting by someone in the PAX cabin. Outside of that, you'll probably do light work tasks like radio comms, review arrival charts, monitor progress, check destination gate status and weather, etc. That only takes up so much time. On turbulent days or in convective weather you'll be quite busy plotting the best course and altitude. When your conversations run dry, the weather is nice, and you've got hours to go, now what? The FAA obviously cannot condone anything but a fixed stare at unchanging dials or reading manuals. I wouldn't recommend that on a transcon redeye. Realistically, it's on you to keep yourself alert without becoming distracted by your time killing activity. Read, do a puzzle, look out the window, eat a meal, ponder the meaning of existence, try not to wake up the CA, etc.
Second, the E175 is a pilot friendly plane. Is it a boring plane to fly? No. What makes a flight boring is more a matter of who you are flying with. From a cruise flight perspective, there's few differences to a Boeing or Airbus. It automatically determines and selects your speeds, and maintains them with auto thrust. Your flight path is visually displayed laterally and vertically, and the autopilot can be armed to auto start the descent at the proper point. All navigation frequencies are auto tuned, including your landing runway ILS. The cabin pressure is all auto, the cabin temp is controlled by FAs, and any abnormality will be annunciated to you. Your wx radar antenna will auto adjust tilt and gain with altitude. All your ETAs and fuel predictions are in view.
