A B737-300 ENTERS A HOLDING PATTERN INCORRECTLY BECAUSE HIS NAV SYS IS IMPROPERLY PROGRAMMED. THIS OCCURS IN ZID AIRSPACE.

Narrative

LAST MIN HOLDING INSTRUCTIONS ISSUED BY ATC BECAUSE ZOB COULD NOT ACCEPT HDOF. INSTRUCTED TO HOLD AT APE VOR 270 DEG RADIAL; R TURNS; 20 DME LEGS; FL290; EFC XA35Z. CAPT (PF) ENTERED DATA FOR HOLDING INTO FMS WITH FO (PNF) CONCURRING WITH INPUT. PNF USED RAW DATA FOR BACKUP. HOLDING COURSE ENTERED INCORRECTLY; RESULTING IN INCORRECT ENTRY INTO HOLDING AIRSPACE. JUMP SEAT RIDER NOTICED ERROR AND ATC WAS NOTIFIED OF CORRECTION BACK TO HOLDING AIRSPACE. NO CONFLICT; BUT VERY EMBARRASSING. CONTRIBUTING FACTORS: EFC WOULD REQUIRE LNDG SHORT OF DEST DUE TO INSUFFICIENT HOLDING FUEL (MAX TKOF WT LAS- PHL). NO ALTERNATE REQUIRED ON FLT PLAN. WITHOUT ANY PRIOR KNOWLEDGE OF DELAYS AT DEST; FLC BECAME VERY BUSY ALL AT ONCE: 1) CLRED TO A HOLD FIX OFF AIRWAY. 2) MINIMUM FUEL COMPUTATION. 3) FLT ATTENDANT CALLING ON INTERPHONE WITH CABIN PROB. WORKLOAD MGMNT SUFFERED AND THE FMS ERROR WAS NOT CAUGHT IN A TIMELY MANNER. VERY LITTLE TEAM WORK BTWN CAPT AND FO DUE TO EARLIER DISAGREEMENT. JOB WELL DONE BY JUMP SEAT RIDER.
