Encapsulates a Accelerometer component for the flight control system.
Syntax:
Example:
The only required element in the accelerometer definition is the input element. In that case, no degradation would be modeled, and the output would simply be the input.
For noise, if the type is PERCENT, then the value supplied is understood to be a percentage variance. That is, if the number given is 0.05, the variance is understood to be +/-0.05 percent maximum variance. So, the actual value for the accelerometer will be anywhere from 0.95 to 1.05 of the actual "perfect" value at any time - even varying all the way from 0.95 to 1.05 in adjacent frames - whatever the delta time.
