It’s easy to pre-record safety instructions, catering options and so on, because they’re rarely updated.
What if a passenger could choose the language for announcements and an onboard computer system allowed flight attendants to create and send dynamic (that is, not pre-recorded) voice messages? The key challenge here is the dynamic nature of the messages.
Many, if not all, long-distance planes have individual screens today (and local ones have at least different audio channels).
Well, each seat is equipped with headphones.
Considering the quality of the public announcement (PA) systems on the airliners, plus engine noise, crying babies and other disturbances, how can any information be effectively conveyed? Of course, flight attendants don’t typically speak a dozen languages, so they use English, which is not the native language of most passengers. “If your destination is Tallinn, look for gate 123,” “For flight XYZ to Saint Petersburg, proceed to gate 234,” and so on. It’s no wonder, then, that when the plane begins its descent, there’s a barrage of announcements about connecting flights. The vast majority set off for connecting flights to destinations spanning all of Central and Eastern Europe. Every time the plane lands in Vantaa airport, I’m surprised at how few passengers head for the airport exit.
