25.107(e)(3) Take-off speeds
ED Decision 2003/2/RM
In showing compliance with CS 25.107(e)(3) –
a. Rotation at a speed of VR-9,3 km/h (5 kt) should be carried out using, up to the point of lift-off, the same rotation technique, in terms of control input, as that used in establishing the one-engine-inoperative distance of CS 25.113(a)(1);
b. The engine failure speed used in the VR-9,3 km/h (5 kt) demonstration should be the same as that used in the comparative take-off rotating at VR;
c. The tests should be carried out both at the lowest practical weight (such that VR-9,3 km/h (5 kt) is not less than VMCG) and at a weight approaching take-off climb limiting conditions;
d. The tail or tail skid should not contact the runway.
