So you're suggesting that while I Taxy the Aircraft I look down watching the cross on my PFD while the PM also goes heads down watching the Flight Control page to check each surface moves the correct way????????
That sounds like a good way to come to grief.
From the A330 FCTM:---
“Flight Control Check”
PM -Monitor F/CTL page.
PF -Apply full back sidestick followed by full forward sidestick, then release.
PM - "Full up, full down, neutral"
PF -Apply full left sidestick followed by full right sidestick, then release.
PM- "Full left, full right, neutral"
PM -Monitor F/CTL page. Follow through on the rudder pedals to confirm full and correct movement.
PF -Press the PEDAL DISC pb on the steering handwheel, smoothly apply full left and full right rudder and then return the rudder to neutral.
PM -"Full left, full right, neutral"
Ensure that the PM calls are in accordance with flight control inputs
PM Move you own Sidestick as above calling out movements etc.
It's not Rocket Science people.
