Talk:Horizontal situation indicator

The picture in this article is not of a HSI, but rather a VOR direction indicator!

Ignoramus here. Requires info on how to tune-in to a particular VOR. Basys (talk) 21:17, 19 April 2008 (UTC)

This is not a VOR indicator in the picture... It is a Pictorial Navigation Indicator or Horizontal Situation Indicator. Giving you Heading information and alleviating the dreaded reverse sencing of a VOR Indicator.

This article needs a History section!
Who invented the HSI? What year was it introduced? When did it become standard equipment on most passenger aircraft? To what extent have newer military situational displays made it obsolete?

I was shocked by how little I could find online about the history of the invention and adoption of the HSI. Would make great content to improve this article if anyone has the energy for some research... ErikTownsend (talk) 12:20, 23 November 2020 (UTC)
