Final answer:
The CRU-60P oxygen connector is a single block manifold block designed for securing the pilot's oxygen mask to the aircraft's oxygen system, ensuring reliable oxygen delivery during flights. The correct answer is option A.
Step-by-step explanation:
The CRU-60P oxygen connector is a type of single block manifold block used primarily in military aircraft to connect the pilot's oxygen mask to the aircraft's oxygen delivery system. The function of this connector block is to ensure a secure and reliable connection that allows the flow of oxygen when it is needed, especially at high altitudes where the atmosphere contains insufficient oxygen for unassisted breathing. The connector is typically made of durable materials to withstand the rigors of flight conditions.
The standard for restraint harness connectors, the Gentex CRU-60P Connector connects the aircraft oxygen supply hose from panel-mounted oxygen regulators to demand-breathing masks. Designed to assure positive locking and prevent flailing during an ejection, this preferred unit is normally secured to a dovetail mounting plate and attached to an airperson's parachute harness. It connects to a standard three-pin bayonet oxygen mask hose connector, and incorporates an omni-directional disconnect to assure proper alignment of disconnect forces during an ejection. This advanced fitting also warns the pilot when a disconnection has occurred.
