Frequently Asked Questions

What is an octant on an aircraft?

add

An octant is a navigational tool used to measure angles, primarily facilitating the determination of one's position by comparing the altitude of a celestial body to the horizon. While pilots don’t typically use octants anymore, they can be useful to have in case of instrument failure.
