The procedure designation for managing instrument outages in instrument procedures is known as?

• A. Dual Instrumentation/Outage
• B. Single Instrumentation Failure
• C. Instrument Data Reversion
• D. Redundant Equipment Protocol

Answer: (A)

The main idea here is redundancy during instrument procedures. The designation Dual Instrumentation/Outage communicates that the procedure is set up to be flown with two independent sources of instrument data, and an outage (one source inoperative) is accounted for within the procedure. This means you have a defined way to continue safely using either the remaining primary source plus a backup, or a specified degraded guidance method, while maintaining situational awareness and adherence to the procedure’s safety margins. The other options don’t represent the formal designation used to manage instrument outages in procedures, because they don’t convey the explicit dual-source/outage framework that this term provides.
