Final answer:
If the outboard MFD fails, you may not be able to adjust the altimeter setting on the inboard MFD. However, some aircraft may have alternative methods or backup systems to adjust the altimeter setting.
Step-by-step explanation:
If your outboard MFD fails, you may not be able to adjust the altimeter setting for display on the inboard MFD. The altimeter setting is typically adjusted through the outboard MFD, and if it fails, you may lose the ability to make that adjustment.
However, depending on the specific system and configuration, there might be alternative methods to adjust the altimeter setting. For example, some aircraft may have backup instruments or manual controls that can be used to adjust the altimeter setting.
In any case, it is important to follow the appropriate procedures and consult the aircraft's documentation or seek assistance from a qualified technician or operator if you encounter any difficulties with the altimeter setting.
