Non-precision approach

Question 1

what is a Non Precision approach

Answer 1

A non-precision approach provides lateral, but not vertical guidance to a runway. There are various types of non-precision approaches, such as VOR, GPS, and Localizer approaches. Non-precision approaches do not take you as close to the ground as precision approaches (like an ILS). Non-precision approaches are more common in smaller airports, larger airports tend to use the ILS.
