If the airline has signed up for BHM ( Boeing health monitoring),the down link is continuous thro CARS using VHF data or Satcom.<br />That was so in my airline operating B777. I am sure ET with a large fleet of B777 and B787 would have.

The situation prior to JT043 (Lion Air) was a failed AoA (out of range). The situation on JT043 and JT610 was AoA erroneous output - not a failure, not reported as a failure. We don't know for certain on ET302 yet.<br />http://www.boeing.com/commercial/aeromagazine/articles/2014_q3/pdf/AERO_2014q3.pdfPeter Lemmehttps://www.blogger.com/profile/03362394024096042275noreply@blogger.comtag:blogger.com,1999:blog-3991004594884305625.post-72013276265943029202019-03-23T03:56:14.740-07:002019-03-23T03:56:14.740-07:00Hi peter. Thanks for your analysis. As you were as...Hi peter. Thanks for your analysis. As you were associated with Satcom and connected developments, I have a question on MAX. MAX has a fault reporting system similar to B777 or B787, where maintenance message are set and down-linked to maintenance engineering base continuously. Are you aware of any maintenance messages (Fault codes) sent by both crashed planes. I am asking this question because everyone was waiting for FDR data to determine cause. Normally in every incident, these fault messages give an early clue.Anonymoushttps://www.blogger.com/profile/00103271025608214180noreply@blogger.comtag:blogger.com,1999:blog-3991004594884305625.post-70141738778361079212019-03-22T21:58:19.452-07:002019-03-22T21:58:19.452-07:00The FAA issued an AD informing the flight crews of...The FAA issued an AD informing the flight crews of the flight deck effects possible with an AoA vane erroneous indication, the potential for MCAS to kick in, and how to respond with cutout switch. With no data from Ethiopian, the FAA expected that the MCAS issues would not be a factor - the AD should have ensured that.Peter Lemmehttps://www.blogger.com/profile/03362394024096042275noreply@blogger.comtag:blogger.com,1999:blog-3991004594884305625.post-66941003635264000162019-03-18T08:26:44.743-07:002019-03-18T08:26:44.743-07:00BZ (Bravo Zulu)!!!BZ (Bravo Zulu)!!!Anonymoushttps://www.blogger.com/profile/09790437716060313605noreply@blogger.comtag:blogger.com,1999:blog-3991004594884305625.post-36009380514990182282019-03-18T08:08:54.351-07:002019-03-18T08:08:54.351-07:00great analysis Peter ! thank yougreat analysis Peter ! thank youmpetry912https://www.blogger.com/profile/02434530239246909594noreply@blogger.comtag:blogger.com,1999:blog-3991004594884305625.post-34852665276484008172019-03-16T06:19:21.827-07:002019-03-16T06:19:21.827-07:00"I wonder if this is the a new reality, where..."I wonder if this is the a new reality, where open speculation outside of the official investigation becomes actionable."<br /><br />This is in a way self afflicted isn't it?<br />FAA behaved not "neutral, we will wait and see"<br />but "everything is save and super OK".<br /><br />in both cases (787, MAX) overconfidence in decisions and bad process<br />came to light afterwards. <br /><br />Unknownhttps://www.blogger.com/profile/16962092993475855430noreply@blogger.com
