Apollo 16 - Guidance and Control Checklist

The Guidance and Control (G&C) Checklist provides the crew with a quick reference to the actions needed to operate the Command Module Conputer in its Guidance and Navigation functions.  Like similar checklists in aircraft, the Apollo Checklists are intended as memory joggers, and are normally used by one cremember reading out the action, and the other crewmembers carrying out the requisite task.

The Checklists are derived from Volume 2 of the Apollo Operations Handbook, which contains the detailed operating procedures for the various systems in the spacecraft, under both normal and emergency conditions.  The Checklists are then developed through simulation, and from experience in previous missions.  This section contains scans of the 220 pages of the G&C Checklist . 

The basic version of the document here is dated 8 December 1971, 3 months before the intended flight date.  It was then amended by Change A on 17 March 1972 and the handwritten Change B on 29 March 1972.  The Checklist will probably have continued to be amended up until, and during, the flight. 

For faster viewing over a slow connection, individual  pages can be accessed as GIF images.  The separate sections of the Launch Checklist can also be downloaded for viewing in PDF format using Adobe Acrobat
