Which master mode is necessary to align the HMCS?

• A. COMM
• B. NAV
• C. AIRBORNE
• D. GND

Answer: (B)

The correct master mode necessary to align the Heads-Up Display (HMCS) is NAV. This is because the navigation mode allows for the integration of position data, which is crucial for aligning the HMCS accurately. When in NAV mode, the system utilizes various navigation inputs, such as GPS and inertial navigation, to determine the aircraft's position and orientation. This information is essential for successfully aligning the HMCS, as it directly affects how the system projects the information onto the display. In contrast, other modes like COMM mainly focus on communication functions and do not contribute to navigation alignment. AIRBORNE may pertain to general flight conditions and parameters but lacks the specificity required for the alignment of navigation systems. GND, while relevant to ground operations, would not be applicable for aligning the HMCS in flight. Thus, NAV is the most appropriate choice for ensuring accurate alignment of the HMCS.
