TKOF FLAP SETTING IN ERROR. CAUGHT BY FLT CREW BEFORE TKOF.

Narrative

DURING THIS PHASE OF FLT THE FLAP/SLAT HANDLE WAS SELECTED TO 5 DEGS WHILE 15 DEGS WAS REQUIRED. THIS IMPROPER SELECTION WAS INITIALLY MISSED ON THE CHKLIST; HOWEVER WAS CORRECTED BEFORE THE TAXI CHKLIST WAS CALLED COMPLETE. THE ENTIRE FLT WAS NORMAL W/O ANY OPERATION CONTRARY TO THE FEDERAL AVIATION REGS. SUCH POSITIONING ERRORS MAY BE A RESULT OF 1 OR MORE OF THE FOLLOWING: WHEN THE FLT CREW OPERATED 3 SERIES OF ACFT WITHIN A SINGLE ACFT TYPE WITH VARIATIONS ON EACH ACFT WITHIN EACH SERIES. OPERATING THESE DIFFERENT ACFT ON A DAILY BASIS. TRANSFER OF CREWMEMBERS FROM ACFT TO ACFT ON A RAPID FAST MOVING FLT SCHEDULE. SUCH ERRORS MAY BE REDUCED WITH SOME OF THE FOLLOWING SUGGESTIONS: A TYPE OF REGULATORY ENVIRONMENT FOR COCKPIT STANDARDS. FLT CREW SCHEDULING FLTS WITH ACFT WITH MINOR DIFFERENCES AND VARIATIONS. COCKPIT STANDARDS OR LACK THEREOF HAS RESULTED IN VARIOUS AREAS THROUGHOUT THE COCKPIT. CAREFUL REVIEW OF THE COCKPIT CHKLIST CORRECTED THE FLAP SETTING. SUCH MAY NOT ALWAYS BE THE CASE. AN EXAMPLE SEEMS TO BE DEVELOPING IN THE ADVANCED AUTOMATED COCKPIT CONSISTING OF FMS/INS/OMEGA LONG RANGE NAV SYSTEMS. IT HAS BEEN MY EXPERIENCE THE MANY KEYBOARD DIFFERENCES TO ACCOMPLISH THE SAME FUNCTION NOT ONLY OCCURS BTWN ACFT TYPE AND SERIES; BUT NOW MAY RESULT WITHIN THE SAME COCKPIT. SOME TYPE OF REG GOVERNING COCKPIT/KEYBOARD STANDARDS MAY PROVIDE THE ANSWER. AS ALWAYS; CAREFUL CHKLIST REVIEW BY THE FLT CREW IS ALWAYS REQUIRED.
