§25.231. Longitudinal stability and control.
14 C.F.R. § 25.231
Landplanes may have no uncontrollable tendency to nose over in any reasonably expected operating condition or when rebound occurs during landing or takeoff. In addition—
Wheel brakes must operate smoothly and may not cause any undue tendency to nose over; and
If a tail-wheel landing gear is used, it must be possible, during the takeoff ground run on concrete, to maintain any attitude up to thrust line level, at 75 percent of VSR1.
For seaplanes and amphibians, the most adverse water conditions safe for takeoff, taxiing, and landing, must be established.
