 FLIGHT DECK DOOR SIMULATION
-----------------------------
This model simulates the behavior of a flight deck door locking 
control system. It has been connected to a 3D virtual reality 
interactive scene where each AADL devise is bound to a reactive 
3D object (see image).

The simulation can also be run automatically thanks to the 
provided scenario, or interactively with the embedded 2D interface 
that is generated when the simulation starts. To open the 2D 
control board, click on the process icon (fddcontrolsw) in the 
simulation display area.

Simulated behavior is as follows:
- when the pilot puts the switch in the UNLCK position 
(selector = 0), then the door is unlocked (status = 1)
- when the pilot puts the switch in the AUTO position 
(selector = 1), then the door is locked (status = 0), 
but can be temporarily unlocked if the right code is entered 
on the keyboard outside the cockpit (code = 123).
- when the pilot puts the switch in the DENY position 
(selector = 2), then the door remains unlocked (status = 1), 
even if the right code is entered.
