Abstract: A method for controlling speed of an aircraft in the air. The method compares a variation of the aircraft speed in the air with a variation of the aircraft speed on the ground for an identical period, and detects any significant difference between the variations.

Abstract: A method and device for detecting, on the ground, the obstruction of a pressure tap of a static pressure sensor of an aircraft. The device includes a pressure sensor that measures the pressure inside a probe and a heating system for heating the probe. When the heating system is activated, the sensor carries out a first measurement of a parameter dependent on the pressure inside the probe. After a predetermined duration from the activation of the heating system, the sensor carries out a second measurement of the parameter. A central processing unit calculates the difference between the first and second measurements and compares this difference to a predetermined value. A warning device emits a warning signal indicating the detection of an obstruction if the difference is greater than the predetermined value.

Abstract: The invention relates to a method and device for detecting, on the ground, the obstruction of a pressure tap of a static pressure sensor of an aircraft. The device (1) comprises a pressure sensor (2) provided for measuring the pressure inside a probe (4), which has a heating system (9) for heating the probe (4) and which, when the heating system (9) is activated, carries out a first measurement of at least one parameter dependent on the pressure inside the probe (4), and a predetermined duration after the activation of the heating system (9), carries out a second measurement of said parameter. The inventive device also comprises at least one central processing unit (11) for calculating the difference between the first and second measurements and for comparing this difference to a predetermined value, and comprises warning means (13) for emitting a warning signal indicating the detection of an obstruction if the difference is greater than said predetermined value.
