<span>an equation that expresses the gross weight of an aircraft as a function of its landing speed will be given as follows: </span><span> V= √1.223w we make w the subject of the equation, we start by dividing both squaring both sides: </span>V²=(√1.223w)² V²=1.223w next we divide both sides by 1.223 to get : V²/1.223=1.223w/1.223 w=V²/1.223 hence the answer will be w=V²/1.223
