as a logical observer feel I can draw a broad inductive opinion
Yeah, let's use some logic, shall we ?
So if I'm following the anti-sidestick crowd, the reasoning goes like this
- Observation O1 : AF447 stalled out of control and crashed. It was a FBW Airbus equipped with sidestick. Confusion was apparent on the flight deck.
- Observation O2 : QT8501 stalled out of control and crashed. It was a FBW Airbus equipped with sidestick. Confusion was apparent on the flight deck.
- Cherry-Picking C1 : Even though some posters provide links to other accidents involving similar circumstances but no sidestick, such events can simply be ignored (see reply 101 or 188 for example)
- Cherry-Picking C2 : Even though there is a publicly available report on the matter, the sequence of events of AF447 can be totally re-invented as "one guy pulled all the way back for the whole duration, the other guy had no source of information other than his sidestick"
- General Knowledge K1 : Correlation always means causation
- General Knowledge K2 : Absence of evidence always means evidence of absence
Applying K1 to O1 and O2 we easily deduce that sidesticks cause confusion which in turn causes the crash. Especially in light of C2.
Then combining C1 to K2, I easily deduce that no such accidents happen with yokes
Thus sidesticks are the sole responsible for loss-of-control-in-flight events. Thus should be banned. QED.
My 5th grade math teacher would have kicked me out of class with a hurting backside if I had said proposed such a "logical" reasoning...
Regarding loss of control in flight, here is a source that I hope will be considered acceptable (yes it's a Boeing study !)
See page 22
total fatal accidents for commercial jets since 2005, following loss of control : 17 (yes, 17 )
Of which I count 3 for Airbus FBW (also including XL Airways in 2008)
In other words :
***14 yoke-equipped aircraft crashed in the last 10 years due to loss of control, accounting for a whopping 82% of all such crashes ***.
And that's not including all the yoke equipped turboprops...(the main point being the cockpit design, not the engine type)
Hey, let's count the CFIT accidents as well, as those often involve flight deck confusion.
Total fatal LOC-I + CFIT jet crashes since 2005 : 33
Of which Airbus FBW : 5 (adding Afriqiyah in 2010 and Armavia in 2006)
So that's 28 fatal accidents out of 33 (84%) on yoke-equipped jets. And that's taking a conservative view regarding the sticks, because I haven't even looked into whether or not the flight controls might have possibly perhaps contributed to the event. And as I mentioned, turboprops aren't even included.
Sidestick wins ? Of course not, the world is not black and white. And this is not a case of winning and losing anyway
Sidestick doesn't play a role in any of these accidents ? Of course not, the world is not black and white.
But the contribution of the man-machine interface is not clear-cut and must be looked at in a wider context of psycho- and social behaviors, complex system & organisation characteristics, and other such non-obvious aspects.
So can we cut the simplistic sidestick-is-evil crap, please ?
