A Boeing 777-200LR loaded to 92% of its maximum take-off weight takes off from Dubai International Airport (24.4 m elevation) during an average day in July
(34.5 °C) with a standard pressure day (101.3 kPa). Assume that the take off
speed is 376 kmph. What is the minimum coefficient of lift needed at the point
where the aircraft just lifts off the ground? A 777-200 has a maximum take-off
weight is 347,452 kg and its wing area is 427.8 m2
