Re: Individual Wheel Load

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...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

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...

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...

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...
