Abstract

A device for indicating during the flight of an airplane, the approach and the existence of any flight condition characterized by Certain pre‐determined combinations of the variables of acceleration acting on the airplane in a direction substantially perpendicular to the lifting surface of the airplane and the dynamic pressure due to the velocity of the airplane through the air comprising indices having pointers, some of said indices comprising members shaped in accordance with the contour of curves obtained by plotting positive and negative accelerations against dynamic pressure for said combinations, means for moving one of said indices in proportion to the variable of acceleration, said means including an accelerometer, a device responsive to variations in dynamic pressure connected to said indice members, the relative motions of the indices being such that their relative positions indicate at any instant the relation between the actual value of one of said variables and the values of the same variable which would be required to produce one of said combinations at the existing value of the other variable.
