On my previous types: Dash 8's and BAe146's, if we changed the Alt, we would keep a finger on the FCU readout until the other pilot acknowledged the new value. Airbus SOPs require a vocalisation and acknowledgement of any change or new value seen on the PFD, so this covers the cross-check requirement. Some on other threads have said their company SOPs for flying Airbus do not mandate this vocalisation. I would say to those companies beware !
I like the finger on the FCU technique. I’ve never had to vocalise anything but altitudes though. I’ve seen a few YouTube videos and it seems tiring- to be generous. Still, I’d be more comfortable following Airbus SOP to the letter than some random guy’s technique.
