What are the statistics for undershoots for similar types over the same sample period?

Once upon a time Bae146-300 series were landing at Berne, 1300m of runway and none of this 300m wasted real estate merde!

Then all runways were fitted with PAPIs for long-bodied aircraft and we were all forced to aim further down the concrete.

Then people like Mr Boeing insisted on factoring the approach speeds with half STEADY headwind component up to Vref+20kts even though windshear was not necessarily present.

Add to these the average performance of line dogs, some of whom should not have been in the front seats and hey presto we have numerous excursions onto the inhospitable terrain in the overrun area with inevitable hull losses and fatalities/injuries.

It's purely an energy management task corrupted by some rather odd presumptions about how the 'frame behaves in IAS and infection by the large eye-wheel brigade.

Why is the runway threshold marked by "piano keys" and are there any medium category jetjocks out there capable of dropping the 'frame onto the concrete just beyond said markings?

Awaiting the undershoot stats with my tin hat on................🙄
