A system for detecting and responding to a flameout condition in a gas turbine engine includes a probe, a spectral data receiver unit, and a flameout relay. The probe detects a radiation from a gaseous content resulting from a combustion reaction within the gas turbine engine. The spectral data receiver unit processes a signal associated with the radiation for four different wavebands and deduces four different current signals. The flameout relay is triggered to move fueling valves to a shutdown state to halt fuel supply into the gas turbine engine based on at least one of: one or more of the four different current signals meet a predefined condition, or a turbine rotor inlet temperature (TRIT) derived or calculated from the four different current signals is below a temperature threshold or a rate of drop of the TRIT is below a rate threshold.
