Ach, I am not persistent. LOL
Sloppy landings come from sloppy approaches.
When I write "stabilised at 200 ft", read that as.
On centerline, on speed, X-Wind corrected, in gear and flaps landing configuration.
On every landing, one should feel confident in the ability to land the aircraft from this "stable" position.
( Even when fighting a wind or X-Wind, one should be "here" )
But, a wind gust, a deer on the runway, anything can spoil your day.
That is why a GO-AROUND has to be a single move from here till touchdown:
And that is Throttle forward.
All the rest can come later.
= > Throttle forward
= > Positive VVI ( Vertical Velocity Indication) the question was asked. DO not touch ANYTHING untill you have a positive VVI.
And then as per PoH, gear, flaps and so on.
