how do you get the aircraft to say 500 100 50 40 30 20 10

well, ya download a lil thingy for it like at simviation or flightsim or avsim and ya kinda follow the insructions and walla?
believe me its irratating when some limey suddenly starts screaming out the alltitude rite in the middle of a very important flare.
jerks make it so loud that it blows my speakers, so i don't use it anymore

what is it called

s-combo i think was one, there is many, simviation i think it was,
and theres all sorts o stuff like cabin anouncements fasten seat belts, no smoking, blah, blah, blah, its poo-poo

AVSIM-------mwaltcall10.zip

system that calls out the altitude is called GPWS- geound proximity warning system. You get it with FSPassanger.
