An aircraft instrument system that informs the pilot of whether, during the takeoff roll, the aircraft's acceleration rate is sufficient to ensure that V1 speed will be achieved at the expected time (and thus distance), and, if not, how far in distance the aircraft is lagging behind the required acceleration schedule.

[ What is claimed is:] [1.] An instrumentation system for use in aircraft, during takeoff roll from standstill to V1 speed, that shows the pilot continuously the airspeed at which the aircraft should be if it is meeting the acceleration required to be at V1 at the anticipated distance as presented in the manufacturers' approved curves of takeoff acceleration graphs, andwherein a related computer database stores information on said curves of takeoff acceleration graphs of the type and model of said aircraft, with relation to speed versus time on said takeoff roll, and thus distance of the same, and an airspeed indicator continuously displaying the actual speed of said aircraft; andwherein during said takeoff roll up to V1 speed, the said computer continuously governs the progressive movement of a needle in said airspeed indicator that points to the speed at which the aircraft should be if it is meeting said computer-stored acceleration curves based on time.
