I'm sure you meant to say on average 40 Km per day (24 hrs). Sea currents can be anywhere from 0.5 knots to 1.5 knots, averaging at 1.0 kts. Tidal currents can be very high in certain parts of the world, but that’s another subject than normal sea currents. At best, we would sail about 300 Km in a 24hr day.
If we take the 7th pings position and the +-300Km as given, 1that still leaves time and distance traveled by the aircraft after the 7th ping. Lets take the worst-case scenario, that after the 7th ping the aircraft traveled another 59 minutes at 900Km per/hr before crashing into the ocean just before the 8th ping. Add the +-300Km, now you are looking at as much as 1200Km from the 7th ping. But supposing the plane made a directional change after the 7th ping and did not continue flying south but instead flew East, North or West. Now the Area to be searched can be as much as 1,440,000 sq/km from the 7th ping if my calculations are correct. 2
Question. We know the pings from the engines are sent once an hour, but when does the hour start? Is it when the engines are turned on or is there a specific time when the hour start? 3 Secondly, does the pilots know this information? size=150] 4[/size] [In other words, would the pilot of MH370 have known when the 7th ping was sent by the engines so that he can then change course from the 6th and 7th pings, assuming the MH 370 was flying in the same direction between those two pings, of course?
Also, can the pilot physically disconnect the cockpit voice recorder and the data recorder, making the Black Boxes completely useless with no useful information at all if they were ever to be found, other than information left to the point of the cut off. Since other important instruments were turned off, one would expect the same to have been done to the Black Boxes too if it was physically possible, no?
1àI have re-estimate those +- 300Km Kikapu now they are down to +- 181Km. Other factors may increase this error to some degree propably make it +-200 Km.
2à You are not far away in your estimates. That’s why the only chance to find the plane is by accident. All that assuming the whole Inmarsat data is not a fabrication.
3àIt seems from the minute the Engines start they send signals to the satellite. That;s what I understood from their pre-take off data. After the plane gets off they increase in frequency.
The plane took off at 16:41, there were what they call "access requests" and "acknowledgements of user data" at 16:42, 16:43. 16:55 16:56 and at 17:07.
Handshakes 3,4,5 and 6 occured at 1 hour intervals sharp 19:41 20:41 21:41 22:41
Handshake 7 occured 1.5 hours later and ping 8 (the partial handshake 9 minutes after that.
I really don't know the difference between handshakes and "access requests/acknowledgements" and why they did not use all of them. We know that prior to ping/handshake 4 they have used at least 6 data from "access requests/acknowledgements"
4àThe pilots may not know but the satellite does. Look what happenned at 17:07
"17:07 - Last Acknowledged Ground to Air DATA-2 ACARS Message. Link lost at sometime between here and 18:03:41." Also look what else the satellite detected
