Captain's speach for passengers with technical problems
Hello... I'm a copilot in an airline and Several times I hear about passenger that get scary out when captain says "we've got a technical problem with the aircraft and we need to land".
I would like to know, in your country or airlines, how is the best way, what are the best words or sentences to say to the passengers about any problem we have with the airplane when we need to land or return, or even divert, but without say exactlly what is the problem (engine failure, apu fire, flaps problem, etc) to prevent passengers get scary??
