The requirement to have a ground proximity warning system (GPWS) aboard commences at what maximum certified takeoff weight (MCTOW) and authorized passenger configuration?

• A. 10,000kgs; 6 or more passengers
• B. 12,500kgs; 8 or more passengers
• C. 15,000kgs; 10 or more passengers
• D. 20,000kgs; 12 or more passengers

Answer: (C)

The requirement for a ground proximity warning system (GPWS) is specified for aircraft that have a maximum certified takeoff weight (MCTOW) of 15,000 kilograms or more, particularly for those configured to carry 10 or more passengers. This regulation is based on safety standards aimed at preventing controlled flight into terrain (CFIT) incidents, which can occur in various aviation operations. In this context, having a GPWS is crucial because it provides pilots with timely alerts about potential terrain conflicts, thereby enhancing situational awareness and contributing to flight safety. The specified weight (15,000 kgs) and passenger configuration (10 or more) ensure that aircraft which are generally larger and carrying more occupants are equipped with this vital safety system, reflecting the increased risk associated with larger passenger aircraft. The other options involve either lower weight thresholds or fewer passenger requirements, which do not align with the established regulations that mandate GPWS for certain aircraft configurations. By focusing on the specific criteria at which GPWS becomes mandatory, the correct answer highlights the regulatory framework established to ensure the safety of air travel for passengers and crew.
