I work in a sim and we have a function called chatter rate which if switched on gives pre recorded ATC/pilot chat,tends to get in the way of what we are trying to teach so it is generally switched off.
I am ATC, ground engineer ,company freq etc.As for TCAS events we tell the sim what kind of aircraft we want to come at us and from what direction then try to put the pilots off so that it comes as a surprise,it is possible to get the fire truck airbourne but does not do much for keeping it real.
Before doing this job I thought that a lot of what I did on sim checks was pre programed but it is not,if your pilots want to divert then you are busy pushing buttons in the back to pre load WX ETC as well as digging out App plates to give navigation assistance.
Its good fun,you learn a lot watching other pilots do their thing,sometimes good ,sometimes not.
Oh and for you pilots out there we can hear you ident the beacons through our headset so dont try and blag it!(as if you would)
