FEAST test. The First European Air Traffic Controller Selection Test ( FEAST) is a tool that helps Air Navigation Service Providers (ANSPs) identify the most suitable candidates for the job of air traffic controllers. FEAST was designed by and made available by ( EUROCONTROL ), the European Organisation for the Safety of Air Navigation.
Proportional–integral–derivative controller. A proportional–integral–derivative controller ( PID controller or three-term controller) is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control.
Hardware-in-the-loop ( HIL) simulation, also known by various acronyms such as HiL, HITL, and HWIL, is a technique that is used in the development and testing of complex real-time embedded systems. HIL simulation provides an effective testing platform by adding the complexity of the process-actuator system, known as a plant, to the test platform.
LoadRunner is a software testing tool from OpenText. It is used to test applications, measuring system behavior and performance under load. LoadRunner can simulate millions of users concurrently using application software, recording and later analyzing the performance of key components of the application whilst under load.
The Ziegler–Nichols tuning method is a heuristic method of tuning a PID controller. It was developed by John G. Ziegler and Nathaniel B. Nichols. It is performed by setting the I (integral) and D (derivative) gains to zero. The "P" (proportional) gain, is then increased (from zero) until it reaches the ultimate gain , at which the output of ...
A controller designed using classical theory often requires on-site tuning due to incorrect design approximations. Yet, due to the easier physical implementation of classical controller designs as compared to systems designed using modern control theory, these controllers are preferred in most industrial applications.
A launch status check, also known as a "go/no go poll" and several other terms, occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed. For Space Shuttle missions, in the firing room at the Launch Control Center ...
C3 - Senior Controller - a special rating awarded to users at the discretion of their local region/division for seniority/recognition, giving unrestricted access to all ATC in their division I1 - Instructor - validated to train and instruct all virtual Air Traffic Controllers, they have the ability to control the same positions as an enroute ...
