I had a waiver for most of my last cruise for flight hours, but I was one of a few only. OPNAVINST 3710.7T Fig 8-4 is the chart for max recommended.
For me, it was:
Single Piloted A/C column with limits of 6.5 hrs a day, 30 hrs/7 days, 65 hrs in 30 days, 165 hrs in 90 days, 595 hrs in 365 days.
The rest is broken down by:
Multipiloted pressurized ejection seat a/c - 12hrs/day, 50 hrs/7 days, 80 hrs/30 days, 200 hrs/90 days, 720 hrs/365 days
Multipiloted non-pressurized a/c - 12hrs/day, 50 hrs/7 days, 100 hrs/30 days, 265 hrs/90days, 960 hrs/365 days
Multipiloted pressurized a/c - 12 hrs/day, 50 hrs/ 7 days, 12 hrs/30 days, 320 hrs/90 days, 1120 hrs/365 days.
