Which instrument displays glide slope and localizer information?

The instrument that displays glide slope and localizer information is the Primary Flight Display (PFD). The PFD is a critical component of the flight deck in modern aircraft, providing essential information such as airspeed, altitude, and navigation data, including glide slope and localizer indicators for instrument landing guidance.

The glide slope provides vertical guidance during an approach, while the localizer provides lateral guidance, helping the pilot align the aircraft with the runway. This information is crucial for executing an Instrument Landing System (ILS) approach. The PFD consolidates this data into a clear and coherent format, allowing pilots to easily interpret their position relative to the desired flight path during landing.

Additionally, the Integrated standby instrument, Multi-function display (MFD), and Flight management system (FMS) serve different purposes and do not specifically prioritize the real-time display of glide slope and localizer information in the same way the PFD does. The standby instrument generally serves as a backup and may not provide the same level of detail or advanced graphics as the PFD. The MFD often displays navigation information but does not exclusively focus on glide slope and localizer data, and the FMS handles route planning and management rather than real-time flight metrics.
