5. How many newtons of lift are
exerted on the wings of an
airplane that have a total area of
100 m^2 when the difference in
air pressure below and above the
wings is 5% of atmospheric
pressure. Recall atmosperic
pressure is 14.7 psi or 101.3
kPa.
Best efficiency - for climbing, cruising, descent
Increased wing area - for take-off and initial climb
Maximum lift and high drag - approach to landing
Maximum drag and reduced lift - for braking on runway
