Narrative

UNINTENTIONALLY DEPARTED A RWY THAT WAS NOT AUTH BY THE COMMERCIAL CHART USING THE ACTIVE RWY (24) ASSIGNED BY ATC WOULD HAVE BEEN AN 8 KT TAILWIND ON A WET RWY; WITH THE DEP END OF THE RWY HAVING AN APPRECIABLE NEGATIVE RWY GRADIENT; IN CASE OF AN ABORT. THIS MADE A SAFE ABORT QUESTIONABLE. ALL PERFORMANCE AND ARPT NOTES WERE CHKED. ANOTHER CONSIDERATION: THE 'ARPT ATIS' HAD A NOTE STATING; 'TREES PENETRATING THE APCH PATH' TO THE LNDG RWY (RWY 6). THIS WAS NOT LISTED IN THE ARPT NOTAM. THE ABOVE 'ATIS' NOTE AND AN 8 KT TAILWIND; DEPARTING RWY 24 CAUSED A CONCERN ABOUT OBSTACLE CLRNC REQUIREMENTS FOR ENG FAILURE DURING TKOF (SECOND SEGMENT CLB); RWY 6 WAS SELECTED; A REMARK FROM THE CTLR CAUSED US TO RECHK THE PERFORMANCE FIGURES AND ARPT NOTES. THE 'NA' REMARK ON THE COMMERCIAL CHART WAS NOT NOTICED. AFTER LNDG AT THE NEXT STATION; THE 'NA' WAS DISCOVERED. PERFORMANCE CHARTS MADE UP BY COMMERCIAL; DOES NOT REMARK THE 'NA' SHOWN ON THE 'TKOF AND IFR DEP PROC' SECTION OF THE APCH CHARTS. IT SHOWS A 'TURN' REQUIRED AND DEP IN CASE OF ENG FAILURE AND SPECIFIC DEP PROC ON THE 'SPECIAL PROC PLATE' CHKING OTHER COMMERCIAL 'ARPT CHART FORMAT' PLATES WITH THE 'NA' REMARK; OTHER NOTATIONS SUCH AS 'VFR ONLY' ETC; ARE MADE IN THE 'ADDITIONAL RWY INFO.' THE NOTATIONS SHOULD; ALSO BE MADE ON THE PERFORMANCE CHARTS. ALL RWY REMARKS SHOULD BE ENTERED IN ONE LOCATION INSTEAD OF MANY DIFFERENT PLACES. THE PERFORMANCE CHART SHOULD BE THE CENTRAL LOCATION; AS THIS SECTION IS ALWAYS CHKED BEFORE DEP.
