Triangle of Velocity

Question 1

What is your ‘air position’?

Answer 1

It is an imaginary position. It’s where the aircraft would be after a period of time with the given heading and airspeed, but without wind

If we decided to plot this position on a map, we would ignor forcasted wind effects

Question 2

What are the three ways to apply winds to your track?

Answer 2

• Wind triangle
• E6B
• CX-2 or CX-3

Question 3

What is a wind triangle?

Question 4

What is the air vector? What is the wind vector?

Answer 4

The air vector: represents the motion of the aircraft through an air mass. Uses true airspeed and true heading. (drawn with single arrow)

The wind vector: represents the motion of the aircraft over the ground. Uses wind speed and wind direction

Question 5

What two things does every vector need?

Answer 5

Speed and direction

Question 6

What stupid thing do you need to remember when plotting a wind triangle, in terms of the wind direction?

Answer 6

In every other area of aviation, winds are given in the direction the wind is coming from. For example, a wind from 270° is from the west.

In a vector diagram like the wind triangle, wind direction is often stated or drawn as the direction the wind is blowing to. Which is 180°/opposite what every other source is.

Question 7

Wind Triangle diagram

Answer 7

Question 8

What tool makes it so you literally never have to try and draw a wind triangle?

Answer 8

E6B

Question 9

How do you convert KTS to MPH?

Answer 9

KTS x 1.15 = MPH
MPH / 1.15 = KTS
