App Description

Practice VOR holdings and intercepting radials using the HSI.
Very easy to use!
Excellent tool!
The horizontal situation indicator (commonly called the HSI) is an aircraft instrument normally mounted below the artificial horizon in place of a conventional heading indicator. It combines a heading indicator with a VOR/ILS display, reducing pilot workload by lessening the number of elements in the pilot's instrument scan to the six basic flight instruments.
