PID |
Proportional-Integral-Derivative |
Generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired set point by calculating and then outputting a corrective action that can adjust the process accordingly. |

|
UAV |
Unmanned Aerial Vehicle |
|
UTM |
Universal Transverse Mercator |
Coordinate system is a grid-based method of specifying locations on the surface of the Earth. It is used to identify locations on the earth, but differs from the traditional method of latitude and longitude in several respects. The UTM system is not a single map projection. The system instead employs a series of sixty zones, each of which is based on a specifically defined secant transverse Mercator projection |
VNE |
Never Exceed Speed |
Speed that must not be exceeded at any time. |
VPD |
Maximum Demonstrated Parachute Deployment Speed |
Maximum speed at which safe deployment of para.chute has been demonstrated. |
VST |
Stall Speed |
Flight speed at which the aircraft stalls |
