Wind Vector and Airplane Navigation

The video tutorial explains how to determine the deviation of an airplane from its intended course due to wind using trigonometry. It covers vector representation of the airplane's speed and wind, forming a triangle to find the resultant vector, and applying the laws of cosines and sines to calculate the plane's speed relative to the ground and the angle by which it is off course.

What is the initial airspeed of the airplane as it heads due north?

• 800 km/h

• 750 km/h

• 700 km/h

• 600 km/h

From which direction is the wind blowing?

• Southeast

• Northwest

• Southwest

• Northeast

What is the magnitude of the wind vector?

• 50 km/h

• 60 km/h

• 70 km/h

• 80 km/h

What angle does the wind vector form with the vertical axis?

• 30 degrees

• 45 degrees

• 90 degrees

• 60 degrees

Which trigonometric law is used to find the plane's speed relative to the ground?

• Law of Cosines

• Law of Tangents

• Pythagorean Theorem

• Law of Sines

What is the approximate speed of the plane relative to the ground?

• 78.84 km/h

• 750 km/h

• 60 km/h

• 800 km/h

Which trigonometric law is used to find the angle by which the plane is off course?

• East of due North

• West of due North

What is the main factor causing the plane to be off course?

• The wind blowing from the Northwest

• The airplane's weight

• The pilot's error

• The airplane's engine
