7. Position Measures position of Flaps, engine nozzle, landing gear, and pilot input controls. This device is a Honeywell RVDT weighing in at 1/3 pound.

8. Pressure Measures gage, absolute and differential pressures. Used in bleed air, fuel, engine oil and hydraulic fluid pressures applications. Weighs about 5 oz without addition of fitting.

9. Force Used for pilot input measurements, servo- loop feedback, overload protection and payload measurement. Weighs 1.75 lbs Torque sensor weighs about 2 lbs.

10. Radar Sensor Informs the pilot that the enemy has radar pointed at them. An example is the ALR-69. It is a basic fuzz buster for the military. Has a 3 by 9 in Cathode Ray Tube. Cost less then $15000 per unit and weighs approximately 42 lbs.
