The indicator (1A) according to the invention comprises means (13) for determining first and second target values respectively of a variable and of its derivative with respect to time, and display means (5, 6, 7) which depict on a display screen (7) a means of indication (14) of the first target value, which is arranged in such a way as to indicate this first target value on a graduated scale (8), and a means of indication (16B) of the second target value which is associated at least with an indicator element (11) indicating said derivative so that, when the latter points toward said means of indication (16B), said variable of the aircraft becomes equal to and remains equal to said first target value and said derivative is equal to said second target value.

1. An indicator of a variable and its derivative for an aircraft, comprising:first means for determining the variable and its derivative with respect to time; display means which depict on a display screen: to indicate said variable, a graduated scale which bears values relating to said variable and which is rectilinearly mobile past a fixed mark, marking the value of said variable of said aircraft; and to indicate said derivative, an indicator element, second means for automatically determining at any moment a first target value relating to said variable and a second target value relating to said derivative, and wherein said display means furthermore depict on said display screen: a first means of indication of the first target value, which is arranged in such a way as to indicate said first target value on said graduated scale; and a second means of indication of the second target value, which is associated at least with said indicator element so that, when said indicator element points toward said second means of indication, said variable of the aircraft approaches said first target value until said variable of the aircraft is substantially equal to said first target value and as appropriate remains substantially equal to said first target value, while said derivative is substantially equal to said second target value.
