So, how about we have Boeing trainers train the airline TRI/TREs in the real aircraft, and then have the TRI/TREs train the TCs in their grounded fleet, who in turn may train the line pilots, either in real aircraft or in simulators as available.
What a great idea! On top of everything, to assure the maximum chance of this unorthodox scheme's success, first batch of the program's pilots should be volunteers with unwavering faith in Boeing. I suggest using PPRuNe posts professing belief that there's nothing much wrong with the MAX, just with the pilots, as an initial method of fishing out such distinguished airmen.

Depending on who you send up first.

Not necessarily, there are plenty of non-pilot types around PPRuNe threads dealing with B-MAX, professing their belief in Boeing's finest narrowbody. We could send 'em up as safety observers.

I do not think that MAX will have to be fished out of anything in the next few years but I would really like to know if there's any significant difference between fishing the aeroplane out of the Mediterranean and the Java Sea?

I guess that you're familiar with 737 preMAX FCTM claim that it can be flown and landed with stabilizer in any position.

Well, "flown" part probably requires further qualification. Excessive Vee squared might get in a way at the extremes of the stabilizer deflection.

Interweb posting boards are full of superpilots who faced with simultaneous continual trim, stickshaker and airspeed discrepancy would have cut the trim switches and reduced speed. Thank FSM for the proliferation of good quality training and flying folks who are not inhibited by modesty to admit they 'ave received one.

Dude, as a MAX qualified pilot (hey, up to grounding, as an 738 capt, I was lawfully required just to have a look at a couple of PPTs in order to act as a fully qualified commander on revenue MAX flight, no previous sim or line instruction needed) I deeply sympathize with your plight. However, as someone acquainted with the works of McRaney, Milgram, Fromm, Reich, Arendt et. al. I'm not in the very least surprised by the brand loyalty displayed on the MAX topics. Since it's only anonymous bulletin board affecting almost nothing, I don't find it disturbing, just mildly amusing.

Severe statistical improvement of civil transport aviation safety in last couple of decades is not only due to improvement of today's airline pilots performance but it would definitively have been impossible without one.

Such a trend has not been widely observed outside fear-mongering (mostly anonymous) rants.

I'd estimate reasonableness of such an expectation to be poor to nil.

My totally unqualified guess would be because it was cheaper this way.

I find the lack of recent flying experience on MAXes extremely unsurprising.

No!

They do not have anything to do with the trim! They act on elevators!

David Petit Davies' deathless tract is still very much relevant 52 years after the first publication and 48 years after the last revision... and still quite misunderstood. Pages 130 onward apply. It is pretty clear that any stick pusher has to be designed so it can be manually overridden if it is activated unduly. Colgan 3407 is a case in point; pusher activation was really needed, yet the panicked pilot kept pulling ,overriding pusher, and stalled the aeroplane. Data from the catastrophes of PK-LPQ and ET-AVJ are still sketchy, but what little has leaked strongly suggests inability to stop pitch down with control column alone.
