TH-73A Systems Practice Test

The lower part of the Primary Flight Display (PFD) is where navigation data is prominently presented. This section typically includes crucial information such as the aircraft’s current position, flight plan data, waypoints, and route guidance. The navigation data section is designed to aid pilots in making informed decisions regarding navigation, including tracking their course and making necessary adjustments during flight.

Positioning this information in the lower part of the PFD allows for an organized layout where pilots can easily reference it without diverting their attention too far from the primary flight instruments that sit above. This design optimally balances the critical functions of flight navigation with other systems related to aircraft control and situational awareness.
