What do the NAVAIDs appearing in the name of an IAP signify?

The NAVAIDs (Navigational Aids) that appear in the name of an Instrument Approach Procedure (IAP) are essential for providing final approach guidance to pilots during the landing phase of flight. Specifically, they denote the type of navigational assistance being utilized to execute the approach, whether it be based on VOR, ILS, RNAV, or other forms of navigation.

Having NAVAIDs indicated in the IAP is critical for pilots, as these references serve to navigate accurately to the runway and ensure safe landings in accordance with the specific approach procedures. The approach can specify the use of various systems that assist with lateral and vertical guidance as the aircraft descends and aligns with the runway during the final approach.

Other options may pertain to different aspects of flight but do not directly correlate with the specific purpose of the NAVAIDs in the IAP name. Recognizing the significance of these aids is vital for pilots in maintaining compliance with procedures and ensuring a safe approach to landing.
