What is the difference between a precision approach and a PA?
Which of the following is an example of non-precision approach?
- Examples include baro-VNAV, localizer type directional aid (LDA) with glidepath, LNAV /VNAV and LPV. A non-precision approach uses a navigation system for course deviation but does not provide glidepath information. These approaches include VOR, NDB and LNAV.
What are the types of instrument approach procedures?
- There are three categories of instrument approach procedures: precision approach (PA), approach with vertical guidance (APV), and non-precision approach (NPA).
Is the MDA of a non-precision approach greater than a precision approach?
- If a runway has both non-precision and precision approaches defined, the MDA of the non-precision approach is almost always greater than the DH/DA of the precision approach, because of the lack of vertical guidance on the non-precision approach.
