Pablo,
Well lets see,
These figures are WAY approximate, but here goes:-
My 737 produces 40 000lbs thrust.
If it stalls at an AOA of 16 degrees, and the thrust line is parrallell with the chord line, the vertical component of thrust will be :-
40 000 * sine 16= 11025 lbs= 5000KG (Damn! I swear it just came out that neat!!!)
Looking at my (Idle Thrust) stall graphs, a reduction in weight of 5 000 kg at 54.5 tonnes, flap30 gear down reduces stall speed from 119kts to 112kts. Again, neatly, the same magnitude as the difference in your lighty.
Sir, you came on to this forum,brought up this subject, insulted anyone who disagreed with you, and when finally had the facts pointed out to you, responded by saying "It doesn't matter, and I'm too old to change".
If you are to old to stop teaching things which are incorrect, you should consider a career change.
