Which term is commonly associated with GPS Overlays?

• A. LPV approaches
• B. GNSS applications
• C. NDB RWY approaches
• D. PBN procedures

Answer: (A)

The term commonly associated with GPS Overlays is LPV approaches. LPV, or Localizer Performance with Vertical guidance, refers to a type of approach procedure that uses GPS data to provide lateral and vertical guidance to pilots. LPV approaches enable aircraft to fly more precise approaches with a minimum decision altitude, which allows for approach paths similar to those of traditional precision instrument approaches like ILS approaches. GPS overlays are established on existing non-precision approaches where GNSS is used to enhance the guidance provided by traditional navigation aids. This means that when pilots utilize LPV procedures, they are leveraging the advanced satellite technology of GPS to improve their instrument flying capabilities, particularly in terms of accuracy and safety during approach and landing. This is particularly advantageous in areas where ground-based navigation aids may be limited or non-existent. While other terms like GNSS applications and PBN procedures are relevant in the context of modern navigation and flight planning, they broadly encompass various uses of satellite navigation rather than specifically indicating the use of GPS in overlaying existing non-precision approaches, which is the focus of LPV approaches.
