what is the gauge is some airplanes that has two bars, one horizontal and one of them vertical? sometimes it is on the attitude indicator, sometimes it is separate.  i havent found out what this does yet, and am wondering.

do you mean the ILS gauge? used in smaller aircraft i believe to basically intercept the ILS when they are in a perfect cross you are on the glideslope, if the vertical line is to the left or right you need to go the way the bar is and if the horizontal line is up or down again you need to follow it to center it.
I believe thats correct but i will let people correct it all they want

OK

You have a ILS indicator (horizontal and vertical bar)
- The cessna has a round one (OBI 1), close to the other nav instruments
The King air has one on the gyro compass
- The 737 has a single direction bar on the HSI, and arrows on the bottom and right side of the ADI.
- The 777 has a single direction bar on the HSI, and a small direction speck at the bottom

And you have a Flight Path indicator, this gives a hint how to turn the aircraft on the ADI
- The cessna doesn't have one when using a standard panel
- The mooney and the kingair have a yellow one, looks like a stretched and inverted V
- The 737 and 747 have a ILS like indicator, it does the same as the ILS indicator on the OBI 1 when you are on ILS

The bars on the ADI usually are linked to the FD switch, goes together with the autopilot if you use a NAV mode.
The bars on the seperate one are striclty ILS, sometimes combined with the HSI

Hi

Fly the instrument training courses it teaches you all about them, but try and take the exam, it's an impossible joke. :-/
