ED Decision 2003/2/RM

(a)     Aeroplanes may have no uncontrollable tendency to nose over in any reasonably expected operating condition or when rebound occurs during landing or take-off. In addition –

(1)     Wheel brakes must operate smoothly and may not cause any undue tendency to nose over; and

(2)     If a tail-wheel landing gear is used, it must be possible, during the take-off ground run on concrete, to maintain any attitude up to thrust line level, at 75% of VSR1.
