#### Transcript of The Trigonometry behind Aviation

Aviators apply trigonometry to
compute distances
from one place to another. It also helps in avoiding
obstacles of land masses
, and mountains for air travel. Vectors are utilised to determine the
plane routes
by putting into consideration the speed, distance, time as well as direction and force of the wind.
The trig applications of finding the angle of inclination/declination can also come quite handy if your plane wants to miss crashing into various objects.
And if you're still not convinced of how trig relates to aviation, here's a video of a simple math problem, regarding a plane solved with trig.

The Trigonometry behind Aviation
Air speed, ground speed, and wind speed are all vectors of force. By creating triangles with those vectors, we can use trig to solve for them.
These force vectors can be used to predict how far off course the plane will deviate in the presence of wind.
Of course it gets a little bit more complicated when the plane's flight path needs to be altered to adjust to the wind
Just a few feet under 267 and you could be crashing into the Eiffel tower...amongst other taller and larger objects (mountains, canyons, radio towers, etc.)
