HSI Localizer Magic
The HSI is a great instrument, but even seasoned pros can get confused about what to set for a course and which way to correct on a localizer.
Let’s start with an old hangar-flying puzzle. You’re outbound on the localizer back course. Your HSI course points back to the runway and you’ve got a right needle deflection. Which way do you turn?
I get a lot of HSI questions—although rarely that convoluted—now that so many panel mount and portable devices contain an electronic HSI. To better understand the HSI, we’ll have a quick VOR review, then see how the HSI brings it all together.
