Transponders are only used in short range situations in the immediate
vicinity of airports and other air-traffic control nodes. They rely on
line-of-site communications, and so once an aircraft is over the horizon the
transponders are not usable. Also they do indeed only respond to enquiries
from the ground. They do not continuously transmit.

Forgive me if this is a silly question, but what is the transponder for, if
not identifying and locating the aircraft?

Mark,

Absolutely. Could not agree more. There's just no excuse not to have GPS
tracking. It's completely ubiquitous these days. I'm sure that all of the
victims had smartphones with it so why not the airplanes?

Hi Lambert,

yes, I agree with you that the blackbox has a data logging requirement.
However, I presume that we all now also recognise that planes need an
additional robust location identifier.

You are correct that there is no need to mix up the two, I was doing that.
With this in mind, all that airlines need to do is design, build and install
a second device, the 365 day GPS tracker to existing aircraft.  We can leave
the Black boxes as they are until next generation and then assess how to mix
both parts.

Mark
