alt Hacker NewsIf you expect every aircraft to land, it seems to meet the very definition of "normal" operation.
An abnormal landing would be something like trying to land with a broken elevator surface.

And you contend that autopilot makes that situation more dangerous? Do you have any support for this?

The circumstance doesn’t have to be that dramatic to be abnormal.
Landing after a merely unstable approach, too many significant changes too close to landing, increases risk.
Landing too fast may result in overrunning the end of the runway, pilot induced oscillation, or loss of control. Energy being proportional to the square of velocity means the margin doesn’t have to be huge to pose significant danger. Landing too slow risks an aerodynamic stall or worse a spin, which at low altitude is nearly certain to be fatal.
Landing safely with a crosswind requires technique changes. Too much crosswind or “running out of rudder” is extremely dangerous.
Landing after accumulating airframe icing is triply bad because the ice reduces the control surfaces’ aerodynamic effectiveness, makes the airplane heavier, and requires a faster landing.
