Mathematics in Aviation Maintenance
(CHAPTER 3) with Verified Solutions
How do you convert inches to feet when measuring aircraft components?
✔✔To convert inches to feet, divide the number of inches by 12.
If a wing panel measures 72 inches long, how many feet long is it?
✔✔The wing panel is 6 feet long (72 inches ÷ 12 = 6 feet).
What is the formula for calculating the area of a rectangular aircraft component?
✔✔The area is calculated by multiplying the length by the width (Area = Length × Width).
If an aircraft component is 4 feet long and 2 feet wide, what is its area?
✔✔The area is 8 square feet (4 feet × 2 feet = 8 square feet).
Why is it important to measure the weight of aircraft components accurately?
✔✔Accurate weight measurements are crucial for maintaining proper balance and ensuring safe
flight operations.

, If an aircraft weighs 3,500 pounds and you add an additional component weighing 250 pounds,
what is the new weight of the aircraft?
✔✔The new weight of the aircraft is 3,750 pounds (3,500 pounds + 250 pounds = 3,750
pounds).
What is the significance of understanding fractions in aviation maintenance?
✔✔Fractions are important for calculating and measuring parts, especially when dealing with
small components or precise tolerances.
How do you convert a fraction to a decimal?
✔✔To convert a fraction to a decimal, divide the numerator by the denominator.
If a repair requires 3/4 of a gallon of oil, how many gallons is that in decimal form?
✔✔3/4 of a gallon is 0.75 gallons (3 ÷ 4 = 0.75).
What is the Pythagorean theorem, and how is it used in aviation maintenance?
✔✔The Pythagorean theorem (a² + b² = c²) is used to calculate distances and ensure proper
alignment of aircraft components.
