Narrative:
Noticed airspeed at 300 KTS descending through 9000 ft. PF corrected immediately and ATC said nothing about it. We were probably distraction by 2ND runway change as descending through 10000 ft. Main factor for this error was the schedule though. Trips need to be looked at for onerous flight scheduling with no regard to circadian rhythm. On this trip; we arrived from an all nighter into ZZZ; in the morning. 11 hour layover then flew to ZZZ1. 12.5 hour layover then started another long day! This is a complete reversal in our sleep schedule within a 24 hour period. Fatiguing schedules. I have two days off after this trip followed by a 5 day trip. Then 1 day off; followed by another 5 day trip. How safe are these scheduling practices?
