(4) final approach: low Z mode pulse mode - all fire together, length of firing is determinable: 8 msec is minimum (5) contingency? go back to orbiter PLT ... he's got DAP set up in previous configuration (6) .1 ft/sec: (to build up relative rate...) normal .4 ft/sec (~5 or 6 jets) high ~ 1.3x that low ~ 1/9x normal (7) "free" - attitude changes .1 per second drift from RCS (worst case) grav gradient aero angular momentum (8) +- Y,R,P pulse mode [fixed # of jets known length of firings -IECM DAP requirements? (9) no VRCS contamination problems (10) VRCS "walk" in Z (11) use VRCS any time (for gas) 248A Pat Curtin
Transcription Notes:
Could not make caret symbol over Z on first line and line section 10
Could not make upper 2 in .4ft/sec(squared) in line 6
Needs degree sign for .1 degree per second...under line 7
