  5. FLAPS


  6. When flaps are deployed at constant AOA the lift coefficient will? a)Decrease b)Reamain the same c)Vary as the square of IAS d)Increase


  7. When flaps are deployed at constant AOA the lift coefficient will? a)Decrease b)Reamain the same c)Vary as the square of IAS d)Increase


  8. ANSWERS: x Extending flaps in flight will increase the camber of the wings.lncreasing camber will increase the lift at any pont of AOA.So when flaps are deployed at constant AOA,lift coefhcient will increase


  9. Which flaps offer greatest increase in Cl max? a)Plain b)Split C)Fowler d)Slotted fowler


  10. Which flaps offer greatest increase in Cl max? a)Plain b)Split c)Fowler d)Slotted fowler


  11. Deflection of trailing edge flap will? a)Increase critical angle of attack b)Decrease CL max c)Decrease drag d) Decrease critical AOA


  12. ANSWERS: x When leading edge flaps are deployed they lower the leading edge of the wing.This increases the degree to which the nose must be pitched upwards to reach the critical(stalling) angle of the wings.This is usually interpreted as the meaning that the deflection of leading edge flaps increases the critical AOA.Thus the deploy,ent of the trailing edge flaps will have opposite effect that is to decrease the critical AOA


  13. ANSWERS: Deployment of trailing edge flaps prior to landing increases the camber,angle of incidence & aoa of wings.This increases Cl at any given AOA. & so reduces the landing speed & nose up attitude required for landing.lf the flaps fail to deploy then the AOA at any given attitude will be reduced,so a higher nose up attitude & airspeed will be required.Because of higher airspeed,the landing roll will also increase.
