What is a Precision Approach?
A standard instrument approach procedure that has a glide slope/glidepath
What is an example of a Precision approach?
ILS
PAR
What is the difference between ILS and a PAR?
On an ILS, the instruments provide the pilot with the election and azimuth information, where on a PAR the Final Controller (ATC) provides the information to the pilot.
What is a Non-precision approach?
A standard instrument approach procedure in which no electronic glide slope is provided.
What is an example of a non-precision approach?

What is a Final Approach Point? (FAP)
The point (on a non-precision app) where the procedure turn is complete and the descent may start.
What is a Missed Approach Point (MAP)?
A point prescribed in each inst. app. procedure (IAP) at which a missed approach procedure shall be executed if the req visual reference does not exist. (end of the approach)
What is the missed approach point for an ILS/PAR app?
