Question

Select the corresponding examples that form a triangle of velocities.

a) Wind & Windspeed
b) Track made good & ground speed
c) Heading & true airspeed
d) Magnetic track & ground speed
e) Wind & true airspeed
f) Track & ground speed
g) Magnetic heading & ground speed

Answer 1

The examples b) Track made good & ground speed, c) Heading & true airspeed, and g) Magnetic heading & ground speed correctly form a triangle of velocities, as they include the necessary vector quantities for constructing a net velocity in aeronautical navigation.

Step-by-step explanation:

The triangle of velocities is a concept used in physics to analyze the relative motion of objects, such as airplanes, in various wind conditions. In the context of the question, the correct examples that form a triangle of velocities would be combinations of vectors that can be added to determine another vector, such as an aircraft's actual path over the ground given its intended path and the wind's effect. The examples that form a triangle of velocities are:

• b) Track made good & ground speed
• c) Heading & true airspeed
• g) Magnetic heading & ground speed

These combinations involve headings, airspeeds, and ground speeds which are vector quantities necessary for constructing a triangle to determine net velocity, essential in aeronautical navigation.
