FLOWN LM FLIGHT CONTROL PANEL DIAGRAM SIGNED BY LOVELL AND HAISE.
"Control Display," diagram from the Apollo 13 LM Systems Data Book. Single folded sheet, 28 by 10½ inches, with a "CONTROL DISPLAY" tab. Annotations by Fred Haise in red marker made prior to the Apollo 13 launch.

The only single full-sheet diagram of the Apollo 13 Lunar Module's display and control devices carried on the mission, with over 100 switches, knobs, and meters illustrated. The center panel has the two large FDAIs (Flight Director Attitude Indicators) for the CDR and LMP positions, caution and warning indicators, propulsion readouts, abort buttons, and lunar contact light. Fuse panels 11 and 16 are shown at their relative crew positions with additional panels on the left side of the CDR and the right side of the LMP. The "T-Handle" Thrust Translation Controller Assembly (TTCA) device and the Attitude Controller Assembly (ACA, or the pistol grip joystick) are illustrated plus the panel that has the LM engine start button. The Display and Keyboard (DSKY) for computer interfacing and the Data Entry and Display Assembly (DEDA) for the Abort Guidance Section are along the bottom of the diagram.
With an accompanying TYPED LETTER SIGNED BY FRED HAISE, reading in part: "During training for Apollo 13, I made about a dozen notations in red ink to provide a quick glance reference of details on the LM systems. For instance, I numbered which exact batteries the 'Feed Tie' circuit breakers were tied to – 'Bats 3,4,6' on panel 11 and 'Bats 1,2,5' on panel 16 plus the 'AH' (Amp Hours) available from the Descent Stage and Ascent Stage batteries. These and the other notes turned out to be very useful during our emergency situation during the Apollo 13 flight since all power was being supplied by the Lunar Module after the explosion.
Below the panel 11 circuit breaker diagram, I have inscribed and signed: 'Carried around the moon on Apollo 13. The schematic reads LM-6 as there were no changes to the Controls and Displays on LM-7 Aquarius. Fred Haise, Apollo 13 LMP.'"

In addition, the display diagram has been SIGNED AND INSCRIBED "James Lovell, Apollo 13 CD" in the lower left corner.
