I have entensively studied photo's and video's of 747 landings and it seems to me that the 1,2, & 300 models will make a rather high angle of attack final approach and landing similar to that of the DC-10 , MD-11, and L1011. The 747-400 seems to make a much lower agle of attack approach and landing similar to other aircraft like the 777 and 767. If you look at the specs, the 1,2,300's have a wingspan of 195 ft whihe the 400 has a span of 211. Could the extra lift of the 400 be what makes the low angle of attack landing possible. I would like to hear all comments and questions. Personally as a student pilot a like to make low aoa landing's bacause they facilitate much greater pilot visibility, plus the plane seems to handle better / more responsive, and a smoother landing will usually follows.
