Transcript of Applications of Trigonometry in Flight

By: Gavin Goodson, Andrew Carlson, Will Phrrehdriqksuhn Trigonometry in Flight Landing Optimal Heading When pilots are landing they need to visually maneuver their plane to find an aproach angle. They have to take into account obstructions, noise abatement, other planes, and weather conditions. The standard angle though is 3 degrees. The final approach is usually achieved at 500 feet. Your optimal heading is the direction you should fly
your airplane to compensate for the wind. 500 ft With this you may
find your distance (X) from
your destination using the tangent of 3 degrees
( in this example) equals the height (500 ft) over X. Destination Actual Velocity Velocity Velocity of the Wind Start Angle of o.h. from
flight path Angle you must find Path of descent Takeoff Speed If you want to take off successfully, you need to know what angle the wind is coming at you on the runway.

You know what angle the wind is coming at you. You also know how fast it's coming at you, so you'd use cosine to figure out how fast you need to go to take off. Wind speed Wind direction (Degrees) Necessary speed
