Abstract:
A device and method of monitoring the measurement of a fuel flow rate fed to an airplane engine includes delivering the measurement from a mass flowmeter. The monitoring also includes evaluating whether at least the following conditions are satisfied: a signal delivered by the flowmeter is less than a given value; and the engine is running on its own. The measurement is invalidated if these conditions are satisfied simultaneously.
