When a Boeing aircraft is under manual control, the pilots must trim using the wheel.

This is not the case for manual control in a FBW Airbus, where autotrim is active in every control law above Direct.

Airbus Flight Control Laws

Of course, if the Boeing pilots are using Otto from wheels-up to flare, then the definition of "regularly" must be qualified with "when under manual control"

The important distinction is that in training, any manual control segment in a Boeing will require manual trimming, whereas this is not the case with the FBW Airbus types.

[EDIT : Of course, what CONF iture is not stating is that manual trimming becomes more effective with backdrive, so his call for an immediate drop to Direct is less a safety concern than it is a way of servicing his objective of forcing Airbus to go back to back-driven yokes as a PFC. ]
