Chapter Two: The Numbers Behind the Flights
A pilot makes numerous preparations on the ground so that his/her flight in the air will go
as smoothly as possible. One way that pilots do this is through checklists. They will use a
checklist to check each critical piece of equipment on the airplane to see if it is in working
condition.
One of the items on the checklist is the fuel. Just like you need to put gas in a car before
a long trip, you must put enough gas in the airplane to get where you need to go. If you
run out of gas in an airplane, it’s not so good!
Fuel, distance, time, speed, and cost are all interrelated numbers used in aviation. In
this chapter, we’ll take a look at the numbers behind the flights. There are many exercises
that can be practiced using this data. We’ll use our round-the-world flight numbers
to demonstrate these formulas and relationships.
