Question

How do airline pilots know the route they need to follow on a flight?

In: Engineering

Answer 1

There’s a flight plan that knows when to turn how many degrees and etc all programmed in. They have multiple navigation systems for the plane to know it’s location, therein knowing if it’s on course. Most planes take more or less the exact same routes so it’s not really something that has to be modified much.
