Until when is the CRUISE page displayed before being replaced by the WHEEL page?

The CRUISE page is displayed as long as the landing gear is retracted. This is because the display is designed to provide optimal information about the aircraft’s performance and flight status during the cruise phase. When the aircraft begins its descent and the landing gear is extended, it shifts the focus from cruise management to landing preparations, at which point the WHEEL page takes over to show relevant data regarding the landing gear status and other important parameters for approach and landing.

In contrast, when the landing gear is extended, or during critical phases of flight such as final approach or upon reaching the destination airport, it signifies a shift in operational focus from cruising to preparing for landing, necessitating the change to the WHEEL page. Thus, the correct response emphasizes the condition that maintains the CRUISE page until the transition to the WHEEL page is required.
