Final answer:
To perform the timing aspect of a Timed Turn from 0300 to 1500, subtract the starting time from the ending time to determine the duration of the turn.
Step-by-step explanation:
To perform the timing aspect of a Timed Turn from 0300 to 1500, you will need to subtract the starting time from the ending time to determine the duration of the turn.
In this case, to go from 0300 to 1500, subtract 0300 from 1500:
1500 - 0300 = 1200
So, the duration of the Timed Turn is 1200 hours.
