Narrative:

On nov/xa/00, I was a crew member assigned to aircraft abcd, flight abc from sea-bna-fll. I was notified nov/xd/00 that the operational performance computer data had expired prior to the flight on nov/xa/00. I feel the problem could be fixed by adding a program or command to the operational performance computer that will not allow users to operate the operational performance computer with expired data. Callback conversation with reporter revealed the following information: the company has installed laptop type computers in all their aircraft. These do all the aircraft performance, gross weight, and runway length calculations. The computer database is supposed to be checked for currency by the first officer on the first use of the day. He missed the fact that the data was expired.

Title: B737-300 CREW USED OUT-OF-DATE PERFORMANCE INFO.

Narrative: ON NOV/XA/00, I WAS A CREW MEMBER ASSIGNED TO ACFT ABCD, FLT ABC FROM SEA-BNA-FLL. I WAS NOTIFIED NOV/XD/00 THAT THE OPERATIONAL PERFORMANCE COMPUTER DATA HAD EXPIRED PRIOR TO THE FLT ON NOV/XA/00. I FEEL THE PROB COULD BE FIXED BY ADDING A PROGRAM OR COMMAND TO THE OPERATIONAL PERFORMANCE COMPUTER THAT WILL NOT ALLOW USERS TO OPERATE THE OPERATIONAL PERFORMANCE COMPUTER WITH EXPIRED DATA. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE COMPANY HAS INSTALLED LAPTOP TYPE COMPUTERS IN ALL THEIR ACFT. THESE DO ALL THE ACFT PERFORMANCE, GROSS WT, AND RWY LENGTH CALCULATIONS. THE COMPUTER DATABASE IS SUPPOSED TO BE CHKED FOR CURRENCY BY THE FO ON THE FIRST USE OF THE DAY. HE MISSED THE FACT THAT THE DATA WAS EXPIRED.
