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.
