Narrative:

I was notified by a chief pilot that the crew and I operated a flight from ZZZ-ZZZ1. Even after looking at the NOTAMS several times I apparently failed to notice the combination of multiple NOTAMS (ie 3 separate NOTAMS) that left us unable to complete the published single engine procedure and we departed that runway anyway. However; WX at the time was clear and 10+ miles visibility. So even in the event of an engine failure we were able to 'see and avoid.' contributing factors include an extremely long work day (8 hours block; 12 hours duty); large amount of NOTAMS for same airport (sometimes 50 or more); a difficult to read coding system for NOTAMS; poor print quality of the release (ie light ink and poor spacing). In the future I will take more time to read the NOTAMS and confirm if single engine departure procedure is required even in VFR conditions.

Title: AN ACR CAPT RPTS HE AND THE FO MISSED THAT COMBINED NOTAMS LEFT THEM UNABLE TO COMPLETE THE PUBLISHED SINGLE-ENGINE PROC EVEN AFTER CONSCIENTIOUSLY READING THE MANY PAGES OF NOTAMS.

Narrative: I WAS NOTIFIED BY A CHIEF PILOT THAT THE CREW AND I OPERATED A FLIGHT FROM ZZZ-ZZZ1. EVEN AFTER LOOKING AT THE NOTAMS SEVERAL TIMES I APPARENTLY FAILED TO NOTICE THE COMBINATION OF MULTIPLE NOTAMS (IE 3 SEPARATE NOTAMS) THAT LEFT US UNABLE TO COMPLETE THE PUBLISHED SINGLE ENGINE PROCEDURE AND WE DEPARTED THAT RWY ANYWAY. HOWEVER; WX AT THE TIME WAS CLEAR AND 10+ MILES VISIBILITY. SO EVEN IN THE EVENT OF AN ENGINE FAILURE WE WERE ABLE TO 'SEE AND AVOID.' CONTRIBUTING FACTORS INCLUDE AN EXTREMELY LONG WORK DAY (8 HOURS BLOCK; 12 HOURS DUTY); LARGE AMOUNT OF NOTAMS FOR SAME ARPT (SOMETIMES 50 OR MORE); A DIFFICULT TO READ CODING SYSTEM FOR NOTAMS; POOR PRINT QUALITY OF THE RELEASE (IE LIGHT INK AND POOR SPACING). IN THE FUTURE I WILL TAKE MORE TIME TO READ THE NOTAMS AND CONFIRM IF SINGLE ENGINE DEP PROC IS REQUIRED EVEN IN VFR CONDITIONS.
