“LOS RATE, RANGE, RANGE RATE VS TIME FROM TPI” CUE CARD 

FLOWN instrument panel cue card made of heavy stock paper, for use inside the Lunar Module, 3¼ by 4 inches, with four small Velcro squares to verso; small loss to front of card. A LOS (Loss of Signal – for communications) rate curve and rate tables are plotted on a graph vs times for TPI (Terminal Phase Initiation), being a LM ascent engine burn to intercept the Command/Service Module to allow rendezvous after return from the lunar surface.

The three rate tables along the lower edge plot time from TPI in minutes, beginning at 0 to +45. The second table shows decreasing range in nautical miles from 32 to 0, and the third gives the range rates in feet per second from -135 to -33.
