- - Use FoilSim to investigate how an aircraft wing produces lift and drag by changing the values of different factors that affect lift and drag.HI, when we checked this homework in class the GPE was wrong, the loss and the strength of the drag was incorrect. IS there another way to figure out?q: An aircraft is flying straight and level at a certain altitude with a velocity of 214 fps. Determine the power required if the wing area is 115 ft? and the total drag coefficient is 0.067. Assume SSLC (p=0.002377 slug/ft3). Provide answer in ft-Ib/s. and round off to the nearest whole number. Solve using standard English units.

The wing area of the aircraft is 30 m2. During takeoff, the lift coefficient of the aircraft is 0.45. Meanwhile during cruising, the drag coefficient of the aircraft is 0.035. i. Analyze the takeoff speed of the aircraft at standard atmospheric conditions ( = 1.225 kg/m3 )Answer correctly. Here is the Translation.
