SOP to call RAD ALT below 20 ft?Rubbish.
Again,people trying to reinvent the wheel...
If you finished the flare maneuver (pitch up) and your thrust is at idle(without delaying and chopping at 10FT as so many do)then its not time to read this damn RAD Alt but to release the elevator force and let it settle down.
The only useful countdown would be time of flare maneuver..after 3 secs,,let it be.
Chinese fos and in general aim for a smooth touchdown and QAR are a daily reminder for them that the technique to fly it down like the Autoland would is not only not appropriate nor safe.
If passengers really care for smooth landings,then it should always be Captain's landings and their future captains with little hands on will be waiting for them during this dark stormy night...
Being a First officer is the time to make mistakes and learn from them...Captains should only intervene if safety is at risk and not ones pride.
