Question

What are the 3 general types of instrument approaches?

Answer 1

The three types of instrument approaches are the Instrument Landing System (ILS) approach, the Non-Precision Approach (NPA), and the Approach with Vertical Guidance (APV), which includes LPV and LNAV/VNAV approaches.

Step-by-step explanation:

In aviation, there are three general types of instrument approaches that pilots must be proficient in to ensure safe landings in various weather conditions. The first type is the Instrument Landing System (ILS) approach, which provides both lateral and vertical guidance to pilots via radio signals. The second type is the Non-Precision Approach (NPA), which offers lateral guidance but no vertical path, requiring pilots to adhere to a prescribed altitude descent profile. Finally, there is the Approach with Vertical Guidance (APV), which includes approaches like the LPV (Localizer Performance with Vertical guidance) and LNAV/VNAV (Lateral Navigation/Vertical Navigation) that provide a pseudo glide-slope using GPS-based systems or other navigational aids.
