Great writing fdr as well as technical insight. A pleasure to read your views. Especially on the vagaries of the 737 stabilizer trim. Regardless of the MCAS debacle I have long mulled over the fact that stabilizer trim issues that I have witnessed in the sim have had potentially catastrophic outcomes. And to suggest that one of the solutions is the fabled rollercoaster technique implies that there is fundamentally an outdated or even fundamentally flawed design not fit for purpose in 2022. A small elevator combined with a large and powerful stabilizer backed up by a Heath Robinson handle so what can possibly go wrong?
