A helicopter tactile accedence warning system includes a control stick and a tactile warning device attached to the control stick. A computer or micro processor and a keyboard for entering a safe temperature profile are also provided as well as a thermocouple for measuring the turbine output temperature. The computer compares the actual temperature versus the safe temperature profile and generates a signal to activate the tactile warning device when the actual temperature falls outside of the safe temperature profile to warn a pilot to abort the start. The tactile warning device is also activated during flight operations when an over stress condition occurs to thereby warn the pilot to take corrective action. In addition, the tactile warning may be activated at a first frequency as an early warning and then at a second frequency as an indication of imminent danger.

What is claimed is: 1. A helicopter turbine engine over stress warning system comprising: a helicopter; a helicopter turbine engine mounted in said helicopter; a collective and a tactile warning device including a collective shaker operatively connected to said collective; data storage means and means for inputting a safe turbine output temperature profile for startup of the helicopter turbine engine and other safe operating parameters during flight of the helicopter; means for measuring actual turbine output temperature during startup of the turbine engine and for detecting actual turbine output temperatures and other actual parameters during flight of the helicopter; means to activate said tactile warning device when the actual turbine output temperature during startup falls outside of the safe turbine output temperature profile during startup and when the safe turbine output temperature or other safe operating parameters are exceeded during flight operations to thereby warn a pilot to take corrective action; means for increasing the magnitude of the tactile warning when the turbine output temperature reaches its maximum operating temperature; means for determining an impending dangerous condition associated with the other safe operating parameters; and means for increasing the frequency of the tactile warning in response to the impending dangerous condition when the impending dangerous condition is imminent.
