If You See Me Propping, Go Away! (Unless You Wanna Pull A Few) - AVweb

It is clear to me, there is a basic disconnect by designers/engineering/manufacturing, with the art of flying. Automation is supposed to augment or replace hand-flying. To accomplish that, the design team has to clearly understand flying. Not only from the basic lift/thrust/drag/gravity, but how an airplane feels when flying in all regimes of flight. Likewise, when pilots are largely depending on the automation to bear the heaviest burden of the flight from gear up to short final, it is not hard to understand the loss of hand-flying skills. Throw in the cost matrix of both certification for the manufacturer and hand-flying time expense to the airline, we have created the perfect storm of “who’s flying the airplane”.

Where does automation start/end and where does hand-flying start/end? And who or what should be intervening when either the automation or hand-flying skills go south? And what do you do when both systems are failing at the same time?

I have always believed that in both crashes, the crews were doing everything they could to save the airplane. I have always believed they were well trained. So far, the data from both crashes have demonstrated both crews were facing significant conflicting information and initially did exactly what Boeing said needed to be done, in the order Boeing had dictated. When all of that failed, both crews explored other options…all of this in a matter of a short period of time. Even Sully, well prepared for an MCAS event, seems to barely have managed to regain control…and he was in a sim, not an airplane full of people.

As sims are so good to mimic actual flight, it is still only simulation, in a sim in perfect mechanical condition mimicking a brand new airplane. Throw in 800+ hours air-frame/engine time in a particular density altitude/wind/visibility/cloud cover with 800+ hour engines, control responses, etc… in other words an airplane whose dynamics are slightly different than a brand new one.

But a sim does not mimic a “used” airplane. Real life flying in “used”, dirty, chipped, possibly previously abused airplanes is what the art of flying is all about. The art of flying dictates how we handle an airplane that has had much maintenance done on airplane and the degradation that can cause. All of the above contributes to the actual conditions and the flying characteristics of those two MAX airplanes at the very moment MCAS went bonkers. This is where the art of hand-flying is so important.

We are facing the harsh realities of the collision between automation, eroding flying skills, designers disconnected from the realities of used airplanes while actually in flight. Simulation is great, tactile feed-back is sorely needed, but in the end, the art of hand-flying cannot be replaced by automation that believes every flight is in a brand new airplane, in a flight regime that is only as good as the minds of the programmers. And if those programmers do not fully understand the realities of “used’ airplanes” in a largely polluted environment, it is only capable of simulating things in a perfect world.

We don’t live in a perfect world, nor do we fly perfect airplanes.

I like your comment.

With all due respect to earlier posters, Muilenberg’s public announcements amount to little more than carefully worded lawyer-speak. Boeing has circled the wagons and nothing comes out that hasn’t been sanitized by the legal department. What ever internal changes come out of this will be kept behind closed doors, but we can only hope they have learned a lesson.

With regard to cockpit automation, any new system can lead to a deterioration in flying skills if the pilot is willing to let it happen. Let’s face it; it is human nature to allow something that eases our workload to become part of our flying “process” over time. The insidious problem is that sometimes it tries to help when we least expect or don’t need it. Case in point for GA is the new generation of autopilots that include some measure of envelope protection to keep us from exceeding certain airspeed/AOA/bank angle limits. The autopilot, whether turned on or not, begins nudging us back to where it thinks we should be. Good or bad? You decide. Paul B. has legitimate concerns, especially if there are significant new developments coming soon. In the end it is incumbent on all of us to throughly understand how any new system we install works and to what degree it affects how we fly the airplane.

In the USAF at bases where high value / limited quantity airframes exist and flight time is a problem, they use lessor airplanes to “nimble up” the crews. Example, (SR-71), U-2 and B-2 crews use T-38’s to maintain proficiency. I know of other flight operations which do the same thing with GA airplanes. Why couldn’t airlines do the same IF “muscle memory” is a root cause issue?

Sadly, automation is feeding the biases of the beancounters. Every company out there with an airplane also has a beancounter. The more airplanes on the ramp, the more beancounters behind desks. Beancounters are necessary, just like hangers, ticket counters, maintenance facilities, and belt loaders if the company wants to succeed, or at least stay in business. If nothing else, a good group of beancounters will keep the IRS away from the door.
The problem with beancounters is their totally skewed view towards training. While we aviators all “know the value” of good training it is clear that beancounters do not. They, as a group, tend strongly towards treating training as an overly negative cost center. They scream and yell at meetings that training costs too much for the lack of obvious value received. They love CBT because there is no travel of accommodation costs involved. The fewer times that crews have to get formal training per yer the better!! “Save that penny but we will overlook the potential dollar the training could have saved! We can’t define that saved dollar because it doesn’t really exist”. To add to this negative effect, managers everywhere have become thoroughly indoctrinated into this attitude of “save money-cut training”.
Now. computers and automation are putting beancounters and management into a feeding frenzy of cut-cut-cut. Cut training, cut crew members, heck, cut seats in the cockpit. We don’t really need two (or any?) pilots up there, just somebody to make sure the lights stay on. Computers cannot fail, cannot fail, cannot fail…
Beancounters and the management they have influenced will continue to degrade aviation to the point where I, with my 20K+ hours of flight time won’t climb into any aircraft I am not personally sitting at the controls of. Good luck to the rest of the flying public.

“ … I, with my 20K+ hours of flight time won’t climb into any aircraft I am not personally sitting at the controls of.“

If its a MAX Boeing I ain’t goin’?
