A pilot needs a approach the runway at a constant angle of 3°.
\n" ); document.write( "a pilot landing at Edmonton International Airport beings the final approach 30 380 ft from the end of the runway.
\n" ); document.write( " At what altitude should the plane be when beginning the final approach?
\n" ); document.write( ":
\n" ); document.write( "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
\n" ); document.write( "sin(3) = \"h%2F30380\"
\n" ); document.write( "h = sin(3) * 30380
\n" ); document.write( "h = 1590ft is the altitude \n" ); document.write( "
\n" );
