I might be wrong as I am just a student after all
(my excuse for today)
but is there not a self test function for smoke detectors etc. that tests both the sensor itself and the indicating medium i.e. light/buzzer?
Do you have a particular aircraft type in mind?
Other than that, thank you guys for your input, much appreciated and I am reading up and trying to decide.. good to have some anchor point!
@OverRun.. Thanks! you are spot on with everything, one lecturer spend quite a lot of energy making sure we think about this
I have about two weeks to decide and come up with initial report along with my objectives, so.. will keep you posted! And in the mean time keep the suggestions coming!
