If anyone has ever seen the inside a cockpit of an aircraft, it may seem overwhelming to most. Some may even see it as complicated and even hard to use. Just like a car, an aircraft has instruments, but just different types to help guide the plane. In a car, one might see the speedometer, to see how fast the vehicle is traveling. In addition, there is the fuel indicator, to see how much gas the car has left before stopping at a gas station. Also, there is the odometer, to see how far the car has driven-the odometer also helps with scheduling routine maintenance services.
