Which of the following is NOT true about the operation of turbine powered airplanes regarding safety equipment?

The statement that "only passenger aircraft require special safety equipment" is not true because safety equipment requirements apply to all turbine powered airplanes, regardless of whether they are passenger or cargo aircraft. All turbine aircraft must meet specific safety standards and regulations laid out by aviation governing bodies. This includes a variety of safety equipment designed to ensure the safety of all occupants aboard the aircraft, not just passengers.

Moreover, regulations can mandate different safety systems depending on the aircraft's intended operation, and these regulations are applied uniformly across different types of turbine powered aircraft, not solely to those carrying passengers.

In addition, the other statements accurately reflect the requirements for turbine powered airplanes. An alert system is a critical safety feature needed in turbine aircraft, ground proximity warning systems are required in many scenarios to prevent accidents, and non-turbine aircraft—which may include general aviation planes and certain older models—often have different safety equipment requirements that may not meet the same standards as those for turbine aircraft.
