Breakeven load factor, английский
The load factor necessary for an airline to break even. it is a function of the percent of seats filled at a particular yield versus the airlines operating costs.
Dihedral angle, английский
The angle that an aeroplane’s wings make relative to the lateral axis (horizontal plane, when on level ground). a larger dihedral angle gives greater roll(lateral) stability at the cost of efficiency. if the wings angle upwards, it is called the dihedral angle. downward angled wings are said to have an anhedral angle (increasingly referred to as negative dihedral).
