“I think that an overweight landing is severely dangerous in every situation on every aircraft.”

Those who think like this may find that they have mistaken beliefs, particularly when the subject is discussed with the manufacturers. Most aircraft type certifications will clear an overweight landing for a touchdown at or less than 6 ft/sec. Although many design safety margins may compromised e.g. wind, drift, brake energy etc, the manoeuvre is perfectly safe; aircraft continue to follow aerodynamic and mechanical laws. The Captains judgement of safety (safety of life) can override AFM limitations – these situations, operations beyond a limit, should trigger additional thoughts about any change of procedure or other mitigating action.
Just remember that the aircraft is heavy, it will involve higher speed and higher energy (V*2). Opportunities for error arise in judging the higher speed and approach path – you may experience an inbuilt bias to slow down to make the landing scene appear normal. The flare manoeuvre, unless specified, should be the same as normal. Remember that the aircraft has taken off at this or a similar weight – the approach and landing capability does not fall off a cliff edge at MLW.
