Thank you. -----Original Message----- From: dba-tech-bounces at databaseadvisors.com [mailto:dba-tech-bounces at databaseadvisors.com] On Behalf Of Heenan, Lambert Sent: Friday, January 09, 2015 12:48 PM To: 'Discussion of Hardware and Software issues' Subject: Re: [dba-Tech] Downed planes and Black-box technology 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.

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?

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 On 8 January 2015 at 13:56, Heenan, Lambert <Lambert.Heenan at aig.com> wrote: > ???
