VOR and ILS indications in the cockpit are very similar, as they mostly use the same instruments. The most basic instrument that can be used is the CDI (Course Deviation Indicator), and more complex would be an RMI (VOR only), and then a HSI (Horizontal Situation Indicator), which actually contains a basic CDI in the centre.

The CDI indicates which direction the aircraft should fly to get on the desired track, and the amount of deviation. We call these "fly left" and "fly right" indications, depending on which way the indicator goes. You can have 2 dot displays, but more common on training aircraft is a 5 dot display, so you can see the deflection more accurately.

On either display, VORs have a full scale deflection of 10°, meaning that each dot (on a 5-dot display) is a 2° deviation.

ILS Localisers, on the other hand, are much more accurate, with a full scale deflection of only 2.5°, meaning that each dot (on a 5-dot display) is worth only 0.5° of deviation. This is 4 x more accurate than VORs
