  1. Friends with whom I've discussed the MAX believe that the Europeans, (EASA) may not be willing to certify the aircraft until it has a crew alerting system. The reasoning behind this thinking is, every aircraft built in the past four decades has had such a system except the B737, and it has been argued that the absence of such an alerting system contributed substantially to the crew confusion in both MAX accidents. Both JTAR & Congressional Committee Reports reinforce this. Boeing argued strenuously and long against the EICAS requirement due fleet commonality, training & development cos

Apologies if this has been posted previously - From a link in the previous article above: Boeing & Aerospace Business Boeing whistleblower alleges systemic problems with 737 MAX June 18, 2020 at 4:40 pm Updated June 18, 2020 at 9:29 pm Investigators at the scene where the Ethiopian Airlines Boeing 737 MAX crashed shortly after takeoff on March 10, 2019.

Boeing & Aerospace Union for FAA’s safety engineers urges more changes to Boeing 737 MAX before it can fly again Sep. 21, 2020 at 2:54 pm Updated Sep. 21, 2020 at 6:53 pm By Dominic Gates Seattle Times aerospace reporter A union representing Federal Aviation Administration (FAA) airplane safety engineers who work on certifying new aircraft called Monday for substantial upgrades to the flight crew alerting systems and other changes on Boeing’s 737 MAX before the plane is allowed to return to the air. The union’s comments came on the fina

  5. Tx, J.O. Way I read it, there was no EICAS on any B737's but that may not be technically accurate - just going by the report. Pg. 46, 47 of the Committee Report: Engine Indicating and Crew Alerting System (EICAS) Boeing obtained an FAA exception to allow the company to not install an Engine Indicating and Crew Alerting System (EICAS) on the 737 MAX.269 Since 1982, an EICAS or its equivalent among Airbus airplanes has been common in newly certificated transport aircraft. It displays aircraft system faults and failures in the cockpit and helps pilots prioritize responding to multip
  6. In fact, the B737 design has no EICAS at all. On the trim wheel diameter-shrinkage, I did the "how many turns per degree" calculation for the NG/MAX last year sometime using an AMM and the numbers in this article are accurate, (14.6 turns per degree), and as mentioned and as reported in, (IIRC), the Ethiopian accident, the crew together couldn't move the wheel, I don't recall this accurately - I believe it was one of the simulator trials that the pilots couldn't move the wheel...due physical strength limitations due high speed.
  7. Concerns Expressed Over 737 MAX Redundancy, Manual Trim Sean Broderick September 21, 2020 Credit: Boeing WASHINGTON—Calls for an additional angle-of-attack indicator and concerns over the flight crew’s ability to manually trim the aircraft in an emergency are among the issues highlighted in the initial set of comments on the FAA’s proposed requirements to approve the Boeing 737 MAX’s service return. Boeing’s proposed fixes including software modifications that use data from both MAX angle-of-attack (AOA) vanes to activate the maneuve
  8. Same principles at play... Airline self regulation. What could go wrong? It's just not that simple. First of all, SMS is about airlines flight safety management programs, not the manufacturer or the regulator and how each do their work. The manufacturer is expected to adhere to the highest possible standards and the regulator must ensure that that is the case. This whole Boeing thing, from the takeover of Boeing by McDonnell-Douglas in 1997 "reads" like, and I think should be examined from the point of view of NASA's problems which led to both the Challenger and Columbia acc

  10. The plan that tests would be conducted over the U.S. makes either Moses Lake area out of YLW or offshore over the U.S. 200-mile limit out of YVR/YXX likely. Logistics are a bit more complicated if YLW in terms of picking up/dropping personnel. I wish Boeing and certainly the crew and all personnel involved with this work well. It's tough being the lesson for everyone else.
  11. In addition to what I would consider "marginal" lengths to operate an B737-800 off of & into, Boundary Bay may have taxi and/or runway weight limitations. Both YXX & YVR as well as YLW are suitable, though.
  12. Hi AIP; First, it isn't about the popularity of posts that counts . If there is disagreement on matters of serious public interest and not merely an exchange of opinions and cocktail chatter, then when challenged, the parties owe each other evidence that supports their expressed views. The evidence as expressed by experts on the subject of masks is strong and widely available/inspectable by all parties regardless of attitudes towards such prophylactics. Wearing a mask in indoor locations where there are other people and outdoor locations where social distancing is not possible is shown t
  13. The -800 is certified to land with a 15kt tailwind, so how the landing distance was calculated and briefed in the pre-descent phase, what the actual wind was at, say, 100ft and what the touchdown point was are all of interest. Less fatalities than the previous overrun accident, by the same type, on this runway ten years ago -
