How many of today’s pilots have actually hand flown their ‘frame at cruise altitude at max AUW for that level?
Since RVSM the practice has been discouraged or downright forbidden so when the autopilot quits or something else throws the aircraft at the startled crew to handfly then all hell and worse will break out.
I don’t believe the initial training in a simulator can possibly reproduce the ‘bungee cord effect’’ and the IAS v TAS effect.
Therefore by definition the current crop of “flightdeck managers” is incapable of and not qualified to operate.
