Sure, if you trust the correctness of the computer's software with your life and the lives of any passengers. There are popular apps now that do some of what you suggest, especially trip planning.

I've seen enough bugs in my day job to want to at least verify the computer's work and have backup instruments, even if just my own senses. Aerospace software is known for relatively low bug counts[1] but also causing fatal crashes[2].

I trust my car controls to be correct and if they aren't I can brake to a stop if anything else seems off. (Unless of course the brakes stop working!) But since you have to take off to fly, you might not realize you can't control the plane until it's already at dangerous speeds.[3]

2: See https://en.wikipedia.org/wiki/List_of_software_bugs sections on Space, Military, and Transportation for examples.

3: Amazing story about an airliner that took off not knowing its controls had been reversed (a maintenance mistake). Pilots declared "MAYDAY plane is completely uncontrollable we plan to ditch" but eventually figured out how to fly the reversed controls and landed it safely—super impressive. https://www.youtube.com/watch?v=kIc8Rr-cKd8
