When a wing stalls: Group of answer choices The lift is reduced as the air density over the top surface is less than the lower surface Flow separates from the top surface of the wing Flow separates from the top and bottom surfaces of the wing Aircraft wings are designed never to stall The lift stops acting upwards and the plane descends

A 10,000-pound airplane stalls when its 300-ft2 wing reaches a maximum lift coefficient (CLmax) of 2.5. Calculate the airplane's stall airspeed (Vs) in knots during a standard day at sea level. To convert speed to knots, divide ft/sec by 1.69. a- 22.7 kts b- 42.7 kts c- 62.7 kts d- 82.7 kts 2. An airplane is flying at an altitude where the static pressure is 1760.0 lbs/ft2 and the ambient temperature is 44o. Its wing has a surface area of 100 ft2 and a lift coefficient (CL) of 0.8. How much lift (L) would the wing produce flying at 200 knots? Note: to convert speed to ft/sec, multiply knots by 1.69. a- 7,299.16 lbs b- 9,299.16 lbs c- 12,299.16 lbs d- 14,299.16 lbs 3. A 5,000-lb airplane is flying straight and level at 100 knots at an altitude where the air density is 0.002277 slugs/ft3. The wing's surface area is 120 ft2. Calculate the lift coefficient (CL). Note: to convert speed to ft/sec, multiply knots by 1.69. a- 0.08 b- 1.28 c- 2.08 d- 3.28
