The approach path is achieved by extending spoilers the whole approach (I'm not sure if spoiler 1-5 or only partial). Before flare there is a callout "standby - standby - flare", at "flare" the rotation has to be initiated. Touchdowns well within limits. TO has weight limitations of course but on short flights no problem.
RWY length is not the problem, tarmac is!! LCY authorities are studying enlargement. Only after this the A318 might be landing there.
If you ask me its a push further down to the limit but it works...
