A TH-57 Sea Ranger helicopter takes off for a training flight at Naval Air Station Whiting Field, June 9, 2014. During the advanced flight training phase of a two-year-long flight school course, future Coast Guard pilots train for 7-8 months in the TH-57, learning aircraft systems and avionics, routine and emergency procedures, flight planning, risk management techniques, and earning their instrument rating, which allows them to fly in clouds and restricted visibility.
