Abstract: An aircraft-based fuel quality monitoring and alerting system is disclosed herein. The aircraft-based fuel quality monitoring and alerting system can include a first sensor configured to output a signal associated with contamination of fuel entering an aircraft through a first fuel inlet. The system can further include a processor configured to determine a first contamination level of the fuel based on the signal and an alerting system configured to deliver an alert if the first contamination level is outside a predetermined range.

Abstract: A multi-tank system and aircraft for dispersing firefighting materials includes a fuselage, a pair of wings, a first storage tank, a second storage tank, a first opening, a second opening, a first closure, a second closure, and an actuator. The first opening is disposed forward of a center of gravity of the aircraft and the second opening is disposed rearward of the center of gravity of the aircraft to maintain stability of the aircraft. The first opening is coupled to the first storage tank and the second opening is coupled to the second storage tank; a fuselage keel beam is positioned around the perimeters of the first and second openings. The actuator is configured to open the first closure and the second closure, in order to disperse firefighting materials such as water, fire retardant, or a mixture thereof.

The first opening is coupled to the first storage tank and the second opening is coupled to the second storage tank. The actuator is configured to open at least one of the first closure and the second closure, in order to disperse firefighting materials such as water, fire retardant, or a mixture thereof.
