 Near the end of the maneuver, the operator negotiates a tight corridor as the PCBM begins to mesh with the ACBM.The operation ends when the RMS Operator either sees four Ready-to-Latch indications on the target ACBM, or concludes that only three can be achieved.Because the RTL is a spring-loaded mechanism, the RMS ends up with stored energy and is left in a state that can resist the separating force.
