LU AVIA 305 Test 3 • Question 1 2.5 out of 2.5 points Which statement is true with respect to Lift Coefficient (CL) and the Effect of Sweepback on Coefficient of Lift - Angle of Attack (AOA) curves. For a safe takeoff, the Critical Field Length must be no greater than the runway available An increase in density altitude has what effect on takeoff performance

An airplane is towing a glider to altitude. The tow rope is 20° below the horizontal and has a tension force of 300 lb exerted on it by the airplane. Find the horizontal drag of the glider and the amount of lift that the rope is providing to the glider. Sin 20° = 0.342; cos 20 °= 0.940.Drag: Cos 20° = D/T (Rearrange) D = Cos 20° X Tension D = 0.940 X 300lbs D = 282lbs Lift: Sin 20° = L/T (Rearrange) Lift = Sin 20° X Tension Lift = 0.342 X 300 lbs

The difference between the CL curves for straight-wing aircraft is that a) the swept wing aircraft has a lower value of CL (max) b) the straight wing aircraft does not fly at as high an AOA for CL (max) c) the swept wing aircraft does not have an abrupt loss of lift at CL (max) d) all of the above d) all of the above

The equation Ta = Q (V2 - V1) shows thatyou can get more thrust from a jet engine by using water injection. you can get more thrust from a jet engine by decreasing the exhaust pipe area. Q in Ta = Q (V2 - V1) is the mass flow (slugs/sec). The mass flow depends onthe cross‐ sectional area of the turbojet engine inlet. the engine inlet velocity. the density of the air at the same point.

Dynamic hydroplaning Is a condition where the tire is lifted completely above the surface of the runway. Can occur at slower speeds and rather than the water lifting the tire from the pavement, the tire slips on a thin film. Is where the water turns to steam and steam pressure lifts the tire from the runway. None of the above Question 2 2.5 / 2.5 pts Directional control during a crosswind takeoff in a C172 should be maintained with coordinated use of ailerons and the rudder. True Fa...
