In the engine model, the throttle-commanded steady-state thrust level and the dynamic response characteristics of the engine are based on airflow rate as determined from a table look-up.

Afterburner dynamics are switched in at a threshold based on the engine airflow and commanded thrust. For example, in a popular electronic circuit simulation program called SPICE, the user will specify a stop-time for the simulation (the simulation assumes the start-time is t=0), and a time increment to use for periodically reporting the simulated circuit's status.

The actual progression of the 'time' variable within the simulation model is. Modelling and Simulation of the Dynamic Behaviour of the Automobile Raffaele Di Martino G.
