On the HSI why do you have to set the heading bug to follow the VOR direction? should NAV hold not do that on its own? Have I missed something?
Thankfully you are far enough away for me to not hear that squirell  |

Short answer is YES, as others have pointed out it's about aircraft navigation.
The reason you have to, as incomprehensible as it seems is that VOR's work on a radio frequency, your air data computer does not. They don't talk to each other until you do something. That includes telling the aircraft where to go, it doesn't read minds any better than a rock garden does.
Your HSI is slaved into the ADC which does all kinds of things, like talk to the auto pilot system. If you don't turn the HSI to follow a radio frequency based navigation beacon who is going to do it? |
