Standard rate at 120 kt TAS
At 120 kt TAS, the coordinated-turn equation gives about 18.2° bank for 3°/second. The 15%-of-TAS shortcut gives 18°.
A full standard-rate turn takes 120 seconds. Use the turn instrument and aircraft procedures in flight rather than treating an estimated bank angle as a command.
Formula and method
A standard-rate turn changes heading about 3° per second. The exact coordinated bank depends on true airspeed.
