| You will travel by jet airliner on a trip around the world. Each
part of your trip is called a leg. Each leg will be between fuel stops.
You will be given two choices of where you can stop on each leg of the
trip.
You will be give the latitude and longitude of the two choices where
you can stop. You will identify and mark these possible stops on your
globe.
You will determine the distance that each possible stop is from the
place you are leaving. One choice is usually too far and too many miles
to stay within the fuel capacity of your aircraft. Choose the shorter
distance.
You must fly within the range of your fuel capacity. Your plane has
just enough fuel to fly 4,000 miles. You must travel less than 4,000
mile on each leg of the trip. You may meet bad weather, which causes you
to use more fuel.
The jet liner travels at the speed shown on the outer ring of your
Horizon Ring globe, 600 miles per hour. Sometimes, you will be asked how
long it takes to travel a leg of the trip.
Use the Horizon Ring to draw and measure the better route for each
leg. When you have finished you should have the complete route plotted
around the world.
| Start in Chicago |
| Remember how to draw a straight line
on a globe? Put your thumbs on each location. Turn the
globe until your thumbs touch the Horizon Ring. Draw a
line using the Horizon Ring as a straight edge that
connects the locations. |

You will start in Chicago, Illinois. 42 N, 88 W. Your first
possible stops are 61 N, 150 W or 21 N, 158 W. Locate both
choices for the first leg of your trip. Write the name of the
cities in the blank space below. Place a check in front of the
better choice. Use the Horizon Ring to draw a straight line
between Chicago and this location.

Your next stop will be at one of these locations: 31 N, 121
E or 36 N, 140 E. Locate both choices for the next leg of your
trip. Place a check in front of the better choice. Again, use
the Horizon Ring to draw the great circle route between these
locations.
