but the only way to calculate Cl (coefficient of lift) is in a wind tunnel
Generally, the bigger the wing (compared to the fuse) the more lift you get and the slower the plane. Jets go faster because their wingspan is shorter. So less lift means you have to go faster to stay up.
you can derive everything from the formula
if you want more lift you can
increase speed (V)
increase wing area (A)
increase wing curvature (Cl)
fly in colder air or higher pressure (P)
