Before the idle kicks on, the MRP must elevate how many degrees?

• A. 10 degrees
• B. 5 degrees
• C. 15 degrees
• D. 0 degrees

Answer: (A)

The main idea here is safe, correct sequencing of the launcher’s moving parts. Before the idle mechanism engages, the MRP must be elevated to ten degrees so the system sits in the proper plane with enough clearance for the idle components to move freely without rubbing the deck or other hardware. This position also aligns any locking interfaces and keeps hydraulic or mechanical loads within design limits when the idle sequence starts.

If you kept it at zero elevation, there wouldn’t be enough clearance for the idle mechanism and it could bind or contact adjacent parts. A smaller rise, like five degrees, wouldn’t provide full clearance, while a larger rise, like fifteen degrees, could push the assembly beyond its travel limits or misalign with the idle components. Ten degrees matches the intended design spec for this step, making the idle activation smooth and safe.
