back of the plane

[looie]

u know the back at the bottom of the fusalage is slanted. wen a  plane lands shud that bit be aligned with the r/w

Generally the back of a plane is curverd (im imagining an airliner here, if you take a flighter jet then its just flat!) maybe light aircraft are flat.. anyway...

when the aircraft lands, the fuselage should be angled up a few degrees from the ground. If you want a better idea, then do the Landing tutorial in flight sim.  8)

Dont believe that angle necessary has to be aligned with the runway, but in general of pitch angle of 4-6 degrees during the flare is normal.

Upwards slant is for takeoff... and the hardware limiter for going over 15 degrees pitch.

FYI, most airliners will hit the tail when exceeding 12 degrees (B744, 777, 737-800/900)
15 degrees may apply to the baby Boeing and A318/319...maybe even A320 as they sit significantly higher on the ground compared to the 737s.
