Patrol ship Haixun 01 discovered a pulse signal with a frequency of 37.5kHz per second, Xinhua reported.
The Xinhua report said a black box detector picked up the signal at around 25 degrees south latitude and 101 degrees east longitude.
It also reported that a Chinese plane spotted several white floating objects in the search area on Saturday.
An Australian pilot on board the plane reported the information to the Joint Agency Coordination Centre.
Where was the last satellite ping from the plane .... was it in/near this area?
I need to go make a strong cup of coffee
:coffeeup:
I am joining you - and settling in for an interesting morning.
A 37.5 kHz pinger can be detectable 1–2 kilometres (0.62–1.24 mi) from the surface in normal conditions and 4–5 kilometres (2.5–3.1 mi) in good conditions.
I am so glad they have been searching much further north today as I have always had a gut feeling that the plane did not have enough fuel to fly so far south. Can't explain why though as it is nothing to do with any mathematical calculations, just looking at the map.
It will be unbelievably fantastic if this ping is from the black box. If it is they must be within a couple of kilometres of it. Wonder how deep that area is?
