For CRG/AMG with EPU emplacement, time starts when the EPU is positioned over which marker?

• A. When EPU is positioned over the hub stake (marker)
• B. When the order is confirmed
• C. When the AMG engine is running
• D. When the EPU is removed

Answer: (A)

Time starts when the EPU is placed over the hub stake marker. This hub stake provides a fixed ground reference so the emplacement timing is standardized and repeatable across crews. Starting the timer at this exact physical position ensures all subsequent steps are measured from the same point. Other moments aren’t used as the start because they’re administrative or conditional actions (confirming the order, engine running, or removing the EPU) and don’t tie to the initial, verifiable emplacement position.
