How many smoke detectors are there on the C-17?

The correct answer is that there are 22 smoke detectors on the C-17. These smoke detectors are strategically placed throughout the aircraft to ensure comprehensive coverage and rapid detection of any fire or smoke hazards that may occur during flight operations or while on the ground. Their placement is critical in maintaining safety and enabling timely responses to potential fire threats, thereby protecting both the aircraft and its occupants.

Having a higher number of smoke detectors enhances the aircraft's safety measures, as it minimizes the risk of undetected smoke in different compartments. The extensive distribution of these detectors underscores the emphasis placed on safety in military aviation, ensuring that emergency conditions can be identified and addressed promptly.
