To HazelNuts39,
The reason for discussing it for so long is that it is not generally true to say that the heavier aircraft decelerates more slowly than the lighter one.
Agreed. When considering AoA of empty AC, AoA may be less, thus producing more efficient aerodynamic profile, than when the same AC weighs more, so it needs more AoA to compensate for more mass = more lift is needed.
That's my understanding.
