When the MODE select switch is set in MAP1, which function is inhibited?

Setting the MODE select switch to MAP1 inhibits the AUTO/MAN Switching function. In the C-17 aircraft systems, different modes are designed to provide specific functionalities and operational capabilities. The MAP1 mode primarily focuses on providing a detailed situational awareness display for navigation and terrain avoidance.

When in this mode, the system prioritizes the display of mapped terrain and relevant data over other functionalities. By inhibiting AUTO/MAN Switching, the pilot has a consistent and stable mapping display that does not switch between automatic and manual modes, which could potentially introduce operational complexity or confusion during critical flight phases. Maintaining focus on the primary MAP1 function enhances situational awareness without the distractions that could arise from auto/manual mode transitions.
