The A-320, 737, CRJ, and so on that I've flown all present me with the same basic information.

What is added with the computers is better and more efficient information presentation. We run around on the autopilot most of the time, it's just that all the other stuff is presented in a more efficient manner. The systems interface on the Airbus is the best I've actually flown (with the 777 going well above and beyond that).

All of them tell you something broke, just on the 737 you get to go on an easter egg hunt to find it... while on other modern airliners there is a centralized message system. The light is the rumor, what is on the screen is the truth.

Now, the DC-9 has no computer interface whatsoever- you're still tuning radios and doing everything like back in the old days. You still crosscheck to make sure you're going to make your crossings and that you're in the right place with the new aircraft, just you are relieved of the grunt task of doing that constantly- just making sure it's doing what it's supposed to be doing. Every airliner that I've flown, the computer from time to time will crap out and test you to see if you're still paying attention. Some of it is from user error, and sometimes (one of the most spectacular examples of this next one was on the 737) the hamster just falls off the wheel.

All in all, if you relegate yourself to computer monitor and stop being a pilot, it will bite you hard. The computers are there just to make the long days easier and keep the higher problem solving levels of your brain available for when the poop really hits the fan.

Every airliner I've flown you can turn it all off and fly it like a 172, even the airbus (though the trimming is done for you)
