I think GPS can still work for tracking. You don't have to wait for the plane to crash to see smoke. Even though GPS may be useless under water or after the crash, it will still give the last known position because the airline operation centrea are always tracking the aircraft. Something like 'Last Known Good Location.'

Under water a GPS is totally useless.
The black box may also emit a distress signal, hence giving away its location

Good people,

its amazing how airlines havent considered the use of GPS in their
tracking systems( IEC Broadband reporting) yet every other
valuable(cars, phones, laptops n even kids!) is GPS enabled. This is
quite shocking considering the NSA's rating of GPS systems as having
accuracy rates of 99.3% for last mile applications. With GPS the crash
site would have been located within minutes of going off radar. Guess
its something our local airlines could score a first in. Over to KQ
and KCAA.

Regards,
nyarotho.
