![]() When you hear pilots talk about the density of the air, they're usually referring to its altitude. ![]() It's how "heavy" or "thick" the air is and it can be affected by many different things, including temperature and humidity. So let's start with the basics, what is density altitude?ĭensity altitude is basically the pressure exerted by the weight of the air on an object. After all, knowing what something is and why it's important will cause the formula to make much more sense to you and it will stick with you more. But when it’s something like this one that we all do as pilots commonly, it’s a pretty straightforward topic to write about!īefore we get into the formulas and ways to calculate density altitude, it's important that you understand what it is. With a technical topic like this one, we performed extensive research to make sure we’re giving you all the right formulas. SkyTough is a site that was created by pilots with a passion for all things aviation, for pilots with a passion for all things aviation like yourself. By the time you're done reading, you'll know what to do next time you get ready to fly. In this article, we will discuss everything there is to know about density altitude, including what it is and how to calculate it. In short, this is the atmospheric pressure that affects an airplane and can cause problems if it's not taken into consideration. If you're a pilot or are thinking of becoming one, then you need to know about density altitude. Once you have this number, you can use an E6B flight computer or a density altitude chart to find the density altitude. To calculate the density altitude, you need to find the pressure altitude by using the following formula: Pressure Altitude = (29.92 - Altimeter Setting) x 1000 + Field Elevation. One of the biggest factors that can affect how an airplane flies is density altitude, and it’s something that must be calculated and known while flying. ![]() Otherwise, you could put yourself, your airplane, your passengers, and any other air traffic at risk. Use this article as your complete guide to learn how to calculate density altitude.Īs a pilot, you need to know how your plane is going to act and how it’s going to fly. It directly impacts an airplane’s ability to fly effectively.Density altitude can affect the way a plane flies from takeoff to landing. Pilots need to know the density altitude to operate aircraft safely during flight. This is due to the fact that air density decreases at higher altitudes. For example, if the density altitude is 5,000 feet at sea level, your airplane is going to take off like it’s already flying at 5,000 feet. What Is Density Altitude?ĭensity altitude is formally defined as the “pressure altitude corrected for nonstandard temperature variations.” That’s just a fancy way of saying density altitude is where the airplane “feels” like it is. Here are quick and easy tips on how to determine density altitude. ![]() Awareness of the density altitude will help you maintain a realistic perspective of the performance capabilities of your aircraft at all times. It can also affect the distance needed to land safely. Specifically, a high-density altitude can impact aircraft performance during takeoff and climb. Airplanes simply cannot perform as effectively in low-density air, potentially putting pilots, passengers, and other aircraft at risk. Learning how to accurately determine the density altitude is a critical skill that all pilots must master to fly safely.
