Lift rapidly decreases once the critical or stalling angle of attack is exceeded this is becauseQuestion 34Select one:a.The airflow around the wing becomes turbulentb.The airflow separates from the top surface of the wingc.The drag exceeds the liftd.The airflow under the lower surface becomes turbulent

An increase in the angle of attack beyond the stalling angle willQuestion 40Select one:a.Cause the lift to immediately decrease to zerob.Result in a reduction of liftc.Produce a decrease in total drag as lift is reducedd.Cause the angle to increase as the centre of pressure moves further forward

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

The main factors that produce lift from a wing areQuestion 17Select one:a.Camber, angle of attack and airspeedb.Dihedral, camber and airspeedc.Chord, angle of attack and airspeedd.Angle of attack, camber and chord

Wing flaps can alter lift most by: altering the air density and airspeed changing the cross sectional depth changing the approach angle altering the aerofoil shape of the wing

In a steady climbQuestion 23Select one:a.Lift is greater than weight, thrust is greater than dragb.Lift is less than weight, thrust is greater than dragc.Lift is greater than weight, thrust is less than dragd.Lift is less than weight, thrust is less than drag
