Bo,
You would get your base salary.
+ 10% of actual block flown.
+ 10% of actual block flown at night.
Then if you were to surpass 70 hours of actual credit in the month you would get the total of those hours at your hourly rate.
Example:
50 block hours with a total of 75 credit for the month. (Deadheads, sit time, standby duty, etc). 20 of those hours were at night.
Basic salary
+5 hours of pay for actual block (50 X 10%)
+2 hours of pay for night (20 X 10%)
+5 hours of pay for Overtime (75 actual credit - 70 guarantee)
Total for the month = 82 hours
Don't count on getting a lot of overtime. Sometimes it is there, sometimes it isn't. With a new aircraft, there would probably be a lot for the first year or so then it would start to dry up.
