Flight banking turns

Question

I recently watched Neil deGrasse Tyson explains modern airplanes doing turns and how the fluid level wouldn’t change inside the cabin when turning.

I’ve tried observing this myself and it didn’t always work as described. Reminder: you should still hang on to your drink just in case.

The comment section below the video mentions something called a “coordinated turn”.

What is it? When do pilots perform coordinated turns? Presumably a set velocity is required to achieve this for a given banking angle?

Answer 1

Almost any time you turn you’re going to do a coordinated turn. Your bank angle is going to be dependent on the speed you’re cruising at, how quickly you need to make the turn and how much your aircraft is able to safely bank.
