[[image]] at 1000', center tanget (SPA3) ~ 2.5° low (that corresponds [[strikethrough]] ) [[/strikethrough]] to SPA3 over [[orbiter?]] C6, not over window)
[[under image]](out of plane)
TECHNIQUE: (1) Pulse size ~ .05
           (2) Deadband About ± ~2.5° (NO INPUT UNTIL 
               DRIFT ~2.5° OFF "CENTER")
           (3) out of plane component will oscillate 
               with orbital period (y-INPUTS NOT REQ'D)
V-BAR APPROACH [[image]]
TECHNIQUE: (1) A/AUTO/NORM - pulse size ~.05
           (2) RANGE RATE ~ 10^-3 x RANGE (1 for 1000', 
               .5 for 500', etc)
           (3) Initial -ẑ input (TO GET CLOSING of 1 
               ft/aec).....
               orbital mechanics of the retrograde burn  
               means orbiter will begin to drift  below 
               TGT (LOWER ORBIT).....
               TECHNIQUE: [[image]]
               As orbiter crosses [[v with a line over 
               it]], put in +x input (Initially go above [[v with a line over it]] because of +X cross-coupling into -Z input)
