Instrument Rating Checkride Practice Test

LPV stands for Localizer Performance with Vertical guidance and it represents an approach that provides both lateral and vertical guidance to the pilot. The key feature of an LPV approach is the ability to use Global Positioning System (GPS) technology to create a precise approach procedure that mimics the precision of an instrument landing system (ILS) approach.

LPV approaches offer significantly improved accuracy compared to traditional non-precision approaches, which lack vertical guidance. LPV approaches typically have lower decision heights, making it possible for a pilot to descend closer to the runway with a higher level of certainty regarding the aircraft's position. This capability allows pilots to maintain a more stable approach profile, reducing the workload and enhancing safety.

Additionally, while an ILS is an example of a precision approach with both lateral and vertical guidance, LPV approaches fall under a category that leverages satellite-based navigation systems, allowing for precision-like performance without the need for ground-based navigation aids. Therefore, the concept of an LPV approach relates directly to the type of approach that provides this vertical guidance, distinguishing it from other approaches that do not include such capabilities.
