I’m curious about this BEA position of not searching to the south.
Is there something in the ACAR’s transmissions that the BEA have not fully explained.
Now I have no expertise in this area, but is it possible that the transmit time and receive time get shorter (by milliseconds) assuming the satellite is to the relative north of transmission, so if the aircraft turned south the transmit/receive time would increase. Someone here must know the answer to this, if not shoot me down in flames for being naive.
