How does broadcasting to a satellite reduce current or future costs?
- justinclift 10y agoAs an initial thought, being able to much more accurately locate missing aircraft sounds like it would be a cost saving. eg: * the many months/years of effort + associated resources for searching would be likely reduced * technical/procedural weaknesses that led to aircraft loss could be better analysed, hopefully leading to reduced further aircraft losses, reduced loss of life Realtime data (other than location) sounds like it would have uses too. Not just alerting for impending or actual failure. On the other hand, would doing this open up potential remote vulnerabilities for aircraft systems? That could have long term crappy-ness attached. :(

- justinclift 10y agoIf the software that does the sending has vulnerabilities in it, that would be bad. Although we can all think of approaches to try to minimise/exclude that possibility... reality often has ways of showing up things people didn't think of. :(

- PeterisP 10y agoWhy would a transmit-only device expose any vulnerabilities in its software? It shouldn't have the physical capability to receive any remote signals, much less act in any way in response to them.
- justinclift 10y agoDepends on how "transmit only" is done. If it's using the equivalent of UDP and no encryption of the data, then you're likely correct. But if the "transmit only" has anything that receives data - even just ack signals for what's sent, let alone something to negotiate encryption - all bets are off. :(
- PeterisP 10y agoYou're thinking a few OSI layers too high. Any such radio communications from similar systems have one-way broadcast as the physical layer. If you don't include a radio receiver, then there is no capability to receive a single bit, much less negotiate encryption; the system throws out a waveform and the rest of the world may figure out what to do with it if they manage to receive it.
- justinclift 10y agoThanks. :)
- dave2000 10y agoThe point of this data is to understand why planes crash (or how were hijacked) so that design faults, defects and crew procedures can be altered to prevent them happening again.
- throwaway_xx9 10y agoNot many airliners are lost, so how is your pedantic answer relevant to to answering the question about cost?
- lallysingh 10y agoIt's a cheap win on the customer service front, when a plane goes down.
