Which button must be used to clear all maintenance faults from the MFL page?

• A. CLR OSB
• B. RESET OSB
• C. MAINT OSB
• D. CHECK OSB

Answer: (A)

The correct choice for clearing all maintenance faults from the Maintenance Fault List (MFL) page is associated with the function that specifically addresses the clearing of error messages or faults. The CLR OSB (Clear Operator Selection Button) is designed precisely for this purpose. When activated, this button removes all displayed maintenance faults, allowing the operator to reset the maintenance display and ensure that any resolved issues are no longer presented in the list. The CLR OSB provides a straightforward way to manage fault displays, which is crucial for maintaining operational efficiency and safety in avionics systems. By clearing the faults, the operator can confirm that the system is functioning without outstanding issues, thereby aiding in effective maintenance management. Other buttons, such as the RESET OSB, might serve different functions, such as resetting systems or components, but they are not specifically designated for clearing faults from the MFL page. Similarly, the MAINT OSB typically relates to maintenance information access rather than clearing faults, while the CHECK OSB may be involved in validating system status or performing checks. Thus, CLR OSB remains the precise option for this action.
