The A320 has the advantage of radio altimeter auto call outs approaching touchdown. The more rapid the call outs, the greater is the possibility of a firm touchdown. In any case, the crew will have had simulator training to gain practice of the different perspective between a 45 metre width (standard) runway and a 29 metre width (narrow) runway. In addition, training should have included day and night maximum crosswind take offs and landings (often 20 kts, but depends on individual company procedures) and engine failure during the take-off run (challenging at low speed). I’ve flown one day to/from 60 metre runways and the next 30 metre runways, never had a landing firmer than 1G 🤥.
