General Description These are the major components of the wing and body overheat detection system: * Wing/body overheat sensing elements * Compartment overheat detection controller * Air conditioning panel. The wing and body overheat detection system uses a single overheat sensing loop. The detector loop in the left and right wing and body supplies overheat and fault signals to the compartment overheat detection controller. This controller uses the signals to give overheat or fault indications in the flight compartment on the air conditioning panel. The fault signals show on the compartment overheat detection module.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
