same   line,   one   of   which   has   a   large   static  
reservoir.   A   simple   remedy   for   this   problem   if   it  
occurs   is   a   tee-­‐fitting   near   the   static   port,   and   a  
dedicated   line   to   the   instrument.   Obviously,   an  

insufficiently-­‐large   orifice   coupled   with   large  
static   reservoirs   can   aggravate   the   problems  
associated   with   lag.     The   pitot   line   MUST   be  
connected   to   the   Gemini   PFD   for   proper  
operation.
 

RFI/EMI  Considerations  

The  instrument  is  shielded  and  does  not  generate  
any   appreciable   level   of   electromagnetic  

interference.     It   has   a   low-­‐current   draw   and  
cannot   contribute   to   RF   interference.     The   solid-­‐
state  gyros  used  in  the  instrument  are  susceptible  
to  outside  stray  RFI.    Be  sure  all  COM  antennas  are  
properly   installed,   tuned,   and   grounded   as   stray  
RFI  can  cause  unreliable  attitude  information.
