List and describe three applications of an internal audit program and describe how control measures and standards are audited in these applications.

Very generic use of the term application here
Examples of 3 audit applications might be: ramp operations, security systems, and personnel OR aircraft, base facilities, and dispatch
Check effectiveness of the controls themselves as opposed to whether or not the controls exist
How you audit the controls and standards depends upon available data. To actually determine if those are working, you would look for evidence, like numbers that tell you if targets are met. Notice the difference where first you are subjectively assessing effectiveness (what is done), but second looking for data as proof of their performance (how well it works).
