Operation Checkout Procedures (OCPs)
Here is the Cover page for an OCP (Operational Checkout Procedure) written for LM3 FEAT (Formal Engineering Acceptance Test) Number 61015, Dated March 30, 1968. The OCP was signed by Howard Wright (S/CAT Deputy) and Red Hafter ( LM 3 Test Team Manager). It was written by me (using the full resources of LM3 Test Team). The OCP was broken up into four volumes and was more than one foot high in size. This was the first time the OCP was run, and took more than 10 days to complete. When testing was completed, there were over one hundred TDR's (Test Discrepancy Reports) written - most of which were procedural errors.
What is an OCP?
The LM Subsystems and Integrated systems were tested as the vehicle was being
assembled in work stands in plant 5. The LM sampled measurements, (i.e., 5x per
sec., 100x per sec. . . . etc.) were transmitted in a Pulse Coded Modulation (PCM)
mode, were down linked , were coupled with plugs in "carry on" measurements,
were signal conditioned and then sent to the ACE (Acceptance Checkout Equipment)
station. The ACE station displayed hundreds of measurements per second to test
engineers manning positions in the ACE room. These measurements were "real time"
displayed on "paged" CRT's, bush recorders, and event lights.
OCP's were written in a script like manner, with the Test Conductor (TC) reading to the appropriate support personnel.
