Narrative:
Inbound V308 to bilit intersection. Cleared to cross bilit at 11000 ft; we were 40 NM from bilit at 14000 ft. Entered 11000 ft into altitude window and FMGC; forgot to start descent and realized it about 5 NM from bilit. Advised ATC. They advised it was not a problem and we started down. Very; very fatigued; it was a 13.5 hour duty day with 5 legs on the last day of trip. Previous day was also 13 hours and 5 legs; fatigue is a constant problem with long duty days. Coffee only goes so far.
