3. Engineers use the formula: V =
aircraft where:
841L
V CS
to determine safe landing speeds of
V = safe landing speed in feet per second
L = gross weight of aircraft in pounds
C = coefficient of lift
S = surface area of wing in square feet
What is the approximate safe landing speed for an aircraft with a gross
weight of 9000 pounds and a wing surface area of 225 square feet, when
the coefficient of lift is 2.8?
