What are you trying to compute? If it’s runway weight bearing, the ACN is the number to use. Individual wheel weight pretty useless otherwise except for some airports in the US that still use it. Load per main tyre, 73900x0.94 / 4 wheels = 17366 kg Load per nose tyre 73900x0.06 / 2 wheels = 2217 kg...Jump to post
Guys, Thanks for the responses. I'm a total amateur when it comes to these technical calculations, but will try to figure it out. Can someone please give me a quick example of how I can calculate a single wheel load using ACN numbers. I tried to understand it but got lost way too fast. I should prob...Jump to post

I think a separate thread makes sense since the 2nd quarter MAX grounded... thread has 41 pages of 4-5 guys regurgitating the same stuff over and over again.

In general, I think flaps should work - but you may also ask why Boeing didn't put flaps down as a possible action into the AD. If Boeing put it on a checklist and your MCAS kicked in at 380 knots, would you extend your flaps? Probably no for obvious reasons. So the checklist should say - if you ar...Jump to post
Did any checklist or procedure suggest that they should have? It does. Issued after Lion Air crash and does not even mention flaps. Anywhere. https://www.aviationtoday.com/wp-content/uploads/2018/11/2018-23-51_emergency.pdf So either this is big omission and negligence by FAA and Boeing or there is...Jump to post

Whether or not those pilots did make errors, nothing excuses the casual and blatant racism that has been seen in these threads.

1. There is no AOA indicator/display or Disagree light in the base package, which is what Lion Air had. So the pilots had no way of knowing. (This is true even for most Airbuses, I believe). Also, I think I read that AOA vanes are not reliable under 60 kts, so they are ignored at low speeds. 2. App...Jump to post

So, for the umpteenth time.....
Please help me understand one thing. Before we even start to blame anyone, I think I read somewhere up this thread that there was a discrepancy in AoA readings even before they took off. If true, why did they take off in the first place? Also, why didn't a mechanic from the saved flight inform other...Jump to post
The NTSB would have skin in the game. An agency of the country that produced the frame. Protecting USA reputation, the FAA and Boeing. That does not mean that I would distrust the NTSB. But an agency is not better or more reliable because it is from the USA. One could rather say that the FAA losing...Jump to post

From everything we've learned so far today, the FAA grounding was the result of two new findings: 1) new satellite data and 2) evidence from the crash site on how the aircraft was configured. The FAA basically stated that the two accidents are very similar. In other words, MCAS was probably at fault...Jump to post
Germany apparently refused the recorders because of a lack of the proper equipment/software to analyze them? You would think there is some sense of urgency to figure out what caused this airplane to crash.

Good article, but IMHO it is a bit unbalanced. It lacks the answer at the question WHY Boeing told his customers/pilots nothing about the existence of MCAS.
