Re: Lion Air 737MAX8 Crashed Jakarta to Pangkal Pinang

I could not find a full logic diagram for Speed Trim Stall recovery. I agree with you this accident could happened to a NG crew not paying attention. Here is the Text I found for the NG: Thanks fadecfault, new and good information. As the AoA bias, for whatever reason, was 20° we are firmly in the ...

Re: Lion Air 737MAX8 Crashed Jakarta to Pangkal Pinang

I guess my question remains. fadecfault or someone else: Is the Stall ID information in the SYMD and FCC different? As is now clear from the traces we are not facing an MCAS range AoA situation for JT610 (or previous flight), the SYMD must have full Stall ID to start the stick shaker. It means the a...

Re: Lion Air 737MAX8 Crashed Jakarta to Pangkal Pinang

Could the remote refer to the elevator feel unit ? I dont think it means left and right. It could, that's why I had the caveat re the red. But it shows something is happening at 22 and at 24. The green goes up at 22 while the red stays, then they change places at 24 when the dive starts. Now red is...

Re: Lion Air 737MAX8 Crashed Jakarta to Pangkal Pinang

I think the FDR trace tells us why the aircraft dives at 24. The 737 has two independent elevator controls, left side which has its own cables to a hydraulic actuator which controls the left elevator (Red trace CCFORCE_PITCHCWSLOCAL_FDR) and an identical system on the right (as I understand it green...

What you are missing is the R64 relay is de-energized with either switch in cutout. Stab Trim Motor would totally be without power.

RE: How Is The A330 Flown Given The Tail Trim Tank?

Thanks all, perfect. I understand the tail trim tank system has been on all Airbus widebodys (A300, 310, 340/330, 380) until the 350. Clever to use the variable camber to also lower trim drag, removes the need for the trim tank system.
