OPERATIONAL TEST AND FUNCTIONAL TEST
An operational test (or operational check) is a task used to determine that an item is operating normally. It does not require quantitative tolerances.
A functional test (or functional check) is a quantitative check to determine if one or more functions of an item performs within the limits specified in the appropriate maintenance data. The measured parameter should be recorded.
