A pilot needs a approach the runway at a constant angle of 3°.
a pilot landing at Edmonton International Airport beings the final approach 30 380 ft from the end of the runway.
At what altitude should the plane be when beginning the final approach?
:
solve this as right triangle where the plane's path to the runway (30380ft) is the hypotenuse, The altitude (h) is the side opposite the angle of 3 degrees
sin(3) = h%2F30380
h = sin(3) * 30380
h = 1590ft is the altitude
