Disclosed is a sensor for detecting temperature of an aircraft. The sensor comprises a temperature sensor elongated with respect to an axis. The temperature sensor comprises a sheath elongated with respect to the axis. The temperature sensor comprises a central conductor disposed within the sheath and elongated with respect to the axis having a conductor material defining a conductor temperature coefficient having a conductor coefficient magnitude. The temperature sensor comprises an optical fiber disposed within the sheath. The temperature sensor comprises a thermistor disposed within the sheath and surrounding the central conductor, the thermistor having thermistor material defining a thermistor temperature coefficient defining a thermistor coefficient magnitude greater than the conductor coefficient magnitude.

A thermionic sensor is disclosed. The sensor includes a sensor housing at least partially defining an emission chamber in which at least a partial vacuum is maintained; a cathode disposed in the emission chamber; an anode disposed in the emission chamber and spaced apart from the cathode; and an electrically conductive layer disposed in the emission chamber facing the anode and cathode. The thermionic sensor is configured to output a detection signal when the anode and cathode are at substantially the same temperature.
