Navigational Question of the Day

What are the 4 situations where course, heading and track are all equal?
JJ Sinclair

I think this is a trick question since I see only 3 choices and I have to
answer 4 questions! Waiting for the answer, since I am not smart enough to
figure it out.

How about from the north pole going south, the south pole going north, and
on the equator east or west. All directions relative to true north and zero
wind.

Zero wind is one of them, but that relationship works anywhere on earth, we
don't have to go to the poles or to the equator to have course, heading and
track equal, in a zero wind situation.

1. At the north pole (all 180).

2. At the south pole (all 0).

3. In absolutely still air.

4. In a trailer ( unless skidding wildly).

One must be in motion to have a track.

Ok, I know three of them what is the 4th.

The only time Course and Heading are equal is when you happen to be
pointed the same direction as your desired course. The also assumes
Coordinated straight and level Flight.(maybe you considered this #4)

If course and Heading are equal the only time The Track will be equal
is:

1. With no Wind

2. With a direct Headwind (on course)

3. With a direct Tailwind (on course)

Very good Brian. You go to the head of the class. The fourth situation where
course, track and heading are all equal would be on takeoff roll, prior to lift
off.

Well, just for fun I'll split a hair. According to the listed sources,
"Track" is defined as the "...intended or desired horizontal direction of
travel..." The term "course over ground" refers to the "..actual path of a
vessel with respect to the earth..."

American Practical Navigation, Bowditch, 1977
Dutton's Navigation & Piloting, Maloney, 1978

Clearly my sources are founded in nautical navigation, and so where did you
locate the aviation definition?
