True or False: Pilots should make all Special Departure Procedure turns at a 15-degree angle of bank unless otherwise stated.

The statement is true because pilots are generally required to adhere to standard procedures for turns during Special Departure Procedures (SDPs) to ensure safety and consistency. When the procedure specifies a 15-degree angle of bank for making turns, it provides a uniform method for all pilots, which helps to maintain a predictable flight path and ensures that aircraft remain within the appropriate airspace confines during departure. The use of a standard bank angle minimizes the risk of excessive maneuvers that could lead to loss of control or increased workload on the pilot, especially during critical phases of flight such as takeoff.

In the context of SDPs, clear instructions regarding turns facilitate effective communication between pilots and air traffic control, as well as between different aircraft operating in proximity. Deviating from this standard unless explicitly stated in the procedure could introduce variability that may compromise operational safety.

Other choices suggest conditions or variations that do not apply universally to all pilots or aircraft operating under the specified procedures. The requirement for a specific bank angle is intended to promote best practices and enhance safety across the board, making the true statement the most accurate in this context.
