It's a basic tenet of air safety that everything can be done by hand when equipment fails.

For example, it's a requirement that you should be able to do vector calculations to account for wind: using only pen-and-paper tools.

Although licensed pilots are allowed to use technology to assist, you shouldn't imagine that the ancient day-to-day processes will change.
