With the advent of GPS, moving maps, tablets with aviation apps, and glass panels driven by software, we now have more choices. Having choices in three displays typically results in heated debates among pilots in FBO lounges and hangars, and especially out in the blogosphere. Those, um, “discussions” focus on three display options.
Our moving maps give us the option to display the map with north up or with track up. (There is a third option: Heading-up, which we will not consider; we are more concerned about the course over the ground, i.e., the “track.” Plus, heading up is similar enough to track up that most of the same arguments apply.)
