Landing on the numbers...
Look, each and every landing should be planned and thought out. Do you have an excellent runway well in excess of requirements for YOUR type of plane? then you don't have to land on the numbers and you have an extra reserve on both ends...stopping scenario and in case you came up short. I know one case who came up short by six inches, and managed to pull the landing gear off on the edge of the runway!
When I was instructing (CFIIMEIATPMEL) at a 2,500 foot strip, I selected the second stripe in the runway centerline as my, and my students, target for landing.
You should ALWAYS have a target, a spot, for landing in mind. I disagree with some of the advice given so far on this thread....IF YOU REALLY WANT TO KNOW HOW TO LAND...buy a copy of "Stick and Rudder" and read about it...especially what is called the stall down landing.
