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

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

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 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

An airplane, approching an airport for landing, had been asked to wait until the runway is clear. The plane flies a "holding pattern," which basically means it will fly in a circle at a constant height and speed. Suppose the 4.900×104 kg airplane has a speed of 405 km/h and needs to fly in a circle with a radius of 6.00 km. To turn, it will bank (tilt) its wings at some angle; this makes the aerodynamic lift force [(L)\vec] point up and to the left as shown below. What does the banking angle need to be for the plane to travel in the circle?

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