The Navigation Computer uses the old-fashioned engineer's slide rule theory except that instead of the scales being presented on a straight ruler they are on 2 circular discs.
Find out how you can add,subtract, multiply and divide if you have never learned how to do arithmetic. Understand what a logarithmic scale is and for what calculations we use the "10 Index" and the "60 Index"

If you look at the circular slide rule face of the navigation computer you will notice that there is no number smaller than 10 or larger than 99. For that reason we insert the decimal point ourselves. But how do we do that? Watch the lecture.
Moreover, you will be able to learn how to solve practical problems, such as finding time to climb between two altitudes at an average climb ratio.
Utilising the "60 Index" we can solve time calculations quickly and accurately. Find out what is the purpose of the yellow scale and how you can convert between minutes and hours.
By remembering that the outer scale is always distance or speed and the inner scale is always time you will be able to solve distance, speed and time calculations in a matter of seconds. In that way you will have more time for the other, more complex questions when sitting your exams. Once you have completed the lecture, practice your knowledge and skills by taking the quiz below.
Fuel consumption problems work exactly like distance/speed/time calculations. We get a fuel consumption per hour, use index 60, and read the answer in minutes. If the result exceeds 60 minutes, we use the yellow scale to read the answer in hours and minutes. The lesson is divided In three parts
Learn how to convert between nautical miles, statute miles,kilometers, yards, feet and metres. These conversions are easy learn and perform. Understand what a common mistake is when doing these types of calculations and how you can avoid it.
For Weight conversions we use the red indices against KG for kilograms and lb for pounds.
Learn how to convert between Imperial Gallons, US Gallons and Litres.
The lecture provides an insight of what specific gravity (CG) is and how to convert volume to weight and vice versa.
Learn how to calculate True Altitude and Density Altitude. Understand how corrected outside temperature and pressure altitude help us to solve such problems.
If you are not completely sure what density altitude is, you will be able to find the answer in this lecture.
The Airspeed indicator measures dynamic pressure, not speed. Before making airspeed conversions, it is essential to understand some definitions, which are clearly explained in this lecture. Find what is the difference between IAS,CAS,EAS and TAS.
The Airspeed Indicator is calibrated to allow for compressibility according to ISA at mean sea level. When flying at any other density, which is nearly always, there is compressibility error which is significant at true airspeeds above 300 knots.
The sound travels at a speed referred to as Mach 1, which is a function of temperature. If you align the 10 index with 60 on the outer scale we will see the Mach number index in the airspeed window. Learn how to use it by watching this lecture.
We will learn how to calculate the heading we must fly to make good a desired track and the groundspeed we will achieve along it. This is the most frequent navigation calculation carried out by private pilots when planning a cross country flight.
Suppose now you are in a Cessna 172 and you know the wind velocity, TAS and HDG and would like to find your track and groundspeed. Learn how to solve this problem by watching the lecture and practice your skills completing Quiz 17.
Wind forecasts are quite accurately these days but usually serve as a general guide for your area. If you want to find out exactly what wind is affecting you in your local area at the present time, the Navigation Computer can be used to find the wind.

Learn how to solve flight planning and navigation calculations, in order to pass your pilot licence ground examinations. Know what examiners are looking for and how to solve problems quickly and accurately without losing time for other more time consuming questions. The course provides you with the support and knowledge which brings you closer to achieving your dream of becoming a pilot.
Majority of students find operating a navigation computer challenging and difficult to learn. This course includes over 22 lectures and 2 hours of content. Lectures are mashup, which means that you will be presented with a video and a PDF document side-by-side so you can easily follow the lecture notes while watching the video. Each lecture is then followed by a quiz, which tests your skills and knowledge and provides you with feedback of your performance. Once you have completed all lectures you will be able to undertake ATPL Practice Exams and identify your strengths and weaknesses. Any questions that may arise from following the course will be answered within 24 hours by the instructor.
I designed this course to be easily understood by student pilots and serve as an exam preparation tool for them. Qualified pilots will also benefit from the course by keeping their skills and knowledge sharp and up to date.
At the end of the course you will be able to perform all types of calculations quickly and accurately, understand the full potential and benefit of the navigation computer and receive a verifiable certificate of completion.
