Ice detection systems for aircraft and related methods are disclosed. A disclosed example ice detection system includes a thermochromic device to sense a temperature of freestream air relative to a temperature threshold, and a hydrochromic device to sense an amount of moisture in the freestream air relative to a moisture threshold. A controller to detect an icing condition in response to the thermochromic device sensing a temperature that is less than or equal to the temperature threshold and the hydrochromic device sensing an amount moisture that exceeds the moisture threshold.

Ice detection systems for aircraft and related methods

Aspects of the present disclosure relate to systems and methods for automated fire detection, such as in aircraft galleys, or other areas where power sources may result in fire or smoke. The system includes one or more detectors to monitor for smoke or fire in an aircraft galley. Upon detection of smoke or fire, a signal is sent from the one or more detectors to a controller. In response to the incoming signal, the controller sends a signal to a galley power source. The signal provided to the galley power source ceases the application of power to one or more devices located in the galley, extinguishing the source of the fire or smoke. The controller may also send a notification signal to alert the crew to the potential fire hazard. A method of operation is also disclosed.
