Landing distance vs. approach angle
Anyone want to take a crack at this one?
What is the effect on landing distance if the approach angle is steepened, approach-speed and configuration kept the same?
Or, to use an actual case. If the CAA "lifts" the approach angle indicated by the VASI/PAPI from 3.3 to 4.5 degrees, and you fly the approach (maintaining the VASI/PAPI) as you always have done, and flare correctly and at the correct Vth, how will this affect your landing distance if you brake/reverse as you've always done?
And if there's an answer, does anyone have any "official" material backing this up?
