![]() If a pilot knows how long each leg of the flight takes, then they know how long the entire trip will take. This extra work has even more benefits, though. Or, in other words, they’ll know where they’ll be in 15 minutes, 30 minutes, or an hour. By figuring out the plane’s speed and course over the ground, the pilot can determine where they are based on how long they’ve been flying. With dead reckoning, a pilot has a little help finding objects in low visibility or when they can’t see from one landmark to the next.ĭead reckoning also involves a little bit of math. Another problem is that it doesn’t provide the pilot with any information like how long it will take to get to their destination and do they have enough fuel left to make it there? Dead Reckoning in Aviationĭead reckoning is one step up from pilotage it adds another level of formality. ![]() For one, if the visibility is low, it could become easy to get disoriented. Pilotage is basic and easy, but it does have a few disadvantages. A pilot can follow a straight line to where they’re going or navigate from one landmark to another along the way. These things are easily visible from the air and shown on aeronautical charts. The same trick works for coastlines or rivers, power lines or railroad tracks. If you want to navigate from Fort Lauderdale to Naples, Florida, and you know that Interstate I-75 connects the two, then why can’t you fly along I-75? Following roads is a great example of pilotage. There’s an old pilot’s joke about flying everywhere “IFR–I Follow Roads.” It’s a fun pun when talking to an instrument-rated IFR pilot, but there is truth in this joke. In its most basic form, it means that the pilot looks out the window. The most basic form of air navigation is called pilotage. And all three are required tasks on the Private Pilot checkride. Pilots use all three types of navigation every day, whether they realize it or not. Types of Navigation in AviationĪll pilots are trained to use three types of navigation: pilotage, dead reckoning, and electronic. Dead reckoning is the skill of figuring out where you are using basic direction, time, speed, and distance calculations. Whatever the precise origins of the term are, it all means the same thing. “Dead,” on the other hand, is when you only have your compass, speed, and course to make estimates between sights.įinally, some believe that the term refers to the accuracy of the results, as in “dead right” or “dead on.” In celestial, “live navigation” is taking sights and making accurate fixes using the stars, planets, or sun. Some believe this was shortened to ded reckoning, which later morphed into “dead.”ĭead reckoning was (or is, depending on your hobbies and professions) an important part of celestial navigation. ![]() What Does the Term Dead Reckoning Mean?įirst, what’s with the funny name? The proper term is “deduced reckoning,” but this is a bit of a mouthful. Then you can estimate your position along your course at any time based simply on how long you have been flying.
