<P> If an obstacle needs to be cleared , the pilot climbs at the speed for maximum climb angle ( V ) , which results in the greatest altitude gain per unit of horizontal distance travelled . If no obstacle needs to be cleared , or after an obstacle is cleared , the pilot can accelerate to the best rate of climb speed ( V ) , where the aircraft will gain the most altitude in the least amount of time . Generally speaking , V is a lower speed than V , and requires a higher pitch attitude to achieve . Normally ground speed for takeoff varies between 250 km / h to 475 km / h in just 2.94 / s . </P>
