What occurs alongside a rapid decay of ITT during an engine failure?

During an engine failure, as the Inlet Temperature (ITT) rapidly decays, the aircraft experiences a loss of thrust or power, which directly correlates to a decrease in airspeed. This is because the engine is no longer able to produce the necessary thrust to maintain the current flight conditions. When engine power is lost, the aircraft cannot maintain the same airspeed, resulting in a reduction in both power and speed.

In this scenario, the initial phase of engine failure often leads to a quick reduction in thrust first, making it crucial for the pilot to identify the issue and implement the appropriate corrective measures, such as executing emergency procedures. While some aircraft might adjust altitude temporarily or experience a momentary increase in certain engine parameters, such as Np (propeller speed), the overall effect is a loss of power and airspeed, which is a critical aspect to manage during such an emergency.
