A light airplane attains an airspeed (speed of the plane with
respect to the air) of 500km/hr. The pilot sets out for a
destination 800km due north, but discovers that the plane must be
pointed 20.0◦ east of due north for the plane to reach there
directly (i.e., the nose/front of the plane is pointed 20.0◦ east
of due north, but the plane itself moves due north as seen by
someone on the ground). The plane arrives in 2.00hr. P,...

2. A recreational airplane has a rectangular wing of constant chord c 1.0m and spanb 10m which uses the same airfoil section from tip to tip. The lift curve slope of this airfoil is shown in the figure below. It is flying at the cruising speed of 50m/s through SSL ISA conditions. Assuming no 3D (finite span) effects (we will cover these in subsequent weeks), compute the following: (a) Cruising at sea level the angle of attack of the wing...

An airplane is heading due north at a constant height with an airspeed of 950 km/h, but there is a constant wind blowing from the northeast at 100 km/h. We will use two-dimensional vectors to work out how far off course the plane is blown, and what its ground speed is. (a) Write down a vector, p, that represents the intended flight path of the plane in one hour. (b) Write down a vector, w, that represents the movement of...
