The best (flattest) glide angle is only achieved atQuestion 48Select one:a.Minimum weightb.The take-off flap settingc.The angle of attack that gives the maximum lift coefficient (CL max)d.The angle of attack that gives the best lift/drag ratio

Lowering flaps in a glide while maintaining the same IAS willQuestion 15Select one:a.Decrease the rate of descentb.Increase the rate of descentc.Increase the stall speedd.Not affect the rate of descent, only the angle of descent

A particular aerofoil is able to produce lift at 0 degrees angle of attack this is because ofQuestion 51Select one:a.The dihedral angle of the wingb.The angle of incidence of the wingsc.The cambered cross-section of the wingd.The aspect ratio of the wing

Gliding upwind as compared to gliding downwind willQuestion 41Select one:a.Increase the dragb.Reduce the groundspeedc.Reduce the stall speedd.Increase the lift

Lowering the flaps from 30 degrees to 40·degrees will result in aQuestion 19Select one:a.Large increase in liftb.Small increase in dragc.Small increase in liftd.Large increase in drag

An ideal glider has drag characteristics given by0D D DiC C C= + , where2D LiC KC=is the induced drag coefficient,LC is the lift coefficient, and K is aconstant. For maximum range of the glider, the ratio0D DiC C is(A) 1(B)13(C) 3(D)32
