What does IPF OVRD do?

• A. IPF OVRD: Sets to override, which equates to battle short. The system will continue operation until totally unable
• B. IPF HIGH: Sets to high, most severe
• C. IPF MED: Sets to medium
• D. IPF LOW: Sets to low

Answer: (A)

IPF OVRD is an override that forces the IPF into battle-short behavior, so the system keeps operating even in degraded conditions until it cannot function any longer. This override is used when you need to maximize availability and maintain Link 16 communications despite faults or damage, accepting continued operation at risk of reduced protection. The other options set IPF to a fixed severity level (high, medium, or low) rather than forcing continued operation; they adjust how strict the IPF protections are but don’t guarantee the system keeps running once it reaches a failure point.
