25 FEB - get multi-phase cue cards . perigee adjust burn OPS 2 burns 1 [[circled]] no error needles until ITEM 27 is executed (UNIV PTG still controls error needles until then) 2 [[circled]]if burn executed post - TIG, guidance doesn't use computed roll but uses current roll 3 [[circled]] guidance looks at [[delta]] Vx,y,z to compute "line-of-sight" of burn in M50 coordinates.... once it computes that, it will try to burn in that direction, even if burn is executed late (doesn't burn LVLH Vx,y,z, but burns toward previously computed M50 attitude .... not good for perigee adjust burns MLR [[double underlined]] (as of 25 FEB- pre Safety panel) voltage transients (in either malf CRT or orbiter) cause pwr trip off. 1 [[circled]] Capacitors added to CRT 2 [[circled]] J5 change for orb problem. As of now, could expect false alarms going from process back to pre-process. Procedures: 1 [[circled]] shut exp down if trip off while in process [[underlined]]mode (tb-bp) 2 [[circled]] assume false alarm & ignore [[underlined]] tb if in pre-process mode NOTE: malf annunciates OVER T, P, travel in piston
