2.1 Characteristics of Aircraft

Parameters to be considered are as follows.

a) size;

b) the number of landing gear and wheels;

c) traction connection point;

d) total weight, empty weight and wheel weight distribution;

Under e) following the direction of the initial motion, aircraft breakaway force as a percentage of the weight of the aircraft.

1) a straight line;

2) turning;

f) under different road surface conditions uniform motion aircraft rolling resistance accounts for a percentage of the weight of the aircraft.

1) horizontal surface;

2) slope;

g) aircraft turning radius;

h) aircraft towing device angle limit;

i) at the following load direction, aircraft towing strength of the device.

1) a straight line forward or backward;

2) minimum intensity direction;

j) thrust engine idle condition.

Airport Environment 2.2 Parameters to be considered are as follows.
