Re: Boeing 737MAX Grounded Worldwide Q2 2019

Trimming is about second or third one learns during pilot training. It shouldn’t require an AD to tell pilots to put the plane in trim. Trim is like managing thrust. In UPT, if you weren’t “in trim” they’d just reach under your arm and push up hard to get you to release the stick, followed by an ab...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

What I think is missing here is that the AD was written for Boeing 737 pilots, not A3XX, Cessna, MS Flight Simulator or even us desk pilots, but 737 pilots. So I would defer to those pilots in any opinion of whether the AD was understandable, clear as mud or crystal. It was written for people who a...

Nobody can argue against the fact that MCAS 1.0 was a horrifically bad design. That said, the key reason for pilots to exist is to get the aircraft on the ground when things go wrong. It doesn't matter if the emergency is caused by a single failure or a chain of 65 events. The job of the pilots is ...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

One factor that has not been mentioned, is the elevation of ADD; 7500 feet. Your climb out will take longer due to the reduced air density. Thus, if you get into a stall situation soon after takeoff, you are a lot closer to the ground! And that means you may not have enough distance between you and...
