Calculating a standard rate of turn

The approximate bank angle required to accomplish a coordinated standard rate of turn (3°/second) can be calculated by dividing the TAS (in knots) by 10 and then adding 7. For example, if your aircraft is flying at 180 knots, a bank angle of 25° would be required.
