B737 nosewheel landing?

[blackmail]

hello gin slinger,

the nosewheel clearance on touch down is function of the body pitch attitude & the body roll angle. the boeing flight training manual, section "manual flight", where for different models 737-2/3/4/5, some charts illustrate the combination of body pitch angles on the vertical axis & body roll angles on the horizontal axis at which nose gear/nacelle/flap track fairing/aft fuselage will contact the runway. a note says: these charts assume struts compressed, flaps40 & are valid for all sink rates. approx. 1 second after touchdown. for flaps 15 & 30, greater clearances exist at some roll angles.

so let us do some math's:according to the graphs, at 0° body angle & 0° roll angle the nose gear touches the rwy. for a b737-300, distance between main gear & nose gear is 12.45m or 40.8464ft.
if we do everything right we come in at 0° pitch attitude/0° roll, flaps40, vref+5(wc<10kts) on a 3°/5% glidepath, in the flare we raise the nose to eg 3°/5% & touch, then simple trigonometric calculations gives nose gear clearance = 40.8464ftx0.05= 2 feet.

0.6°=1%

if we raise the nose 5°/8.3%, then the nose gear clear.= 40.8464ftx0.083= 3.3902512ft.

i think normal flare techniques to be within these values( 3 a 5°).

if we raise the nose to 11° tail strike occurs & nose gear clearance becomes irrelevant.
i let you do all the other intermediate flare combinations.
