✪ Want to Become a Pilot? Looking for a Course to Learn How to Operate a Navigation Computer (CRP5) and Practice Hundreds of Questions. Congratulations - You've come to the right place - Enrol Now!

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.

The Circular Slide Rule - General Calculations
6 Lectures 26:33

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"

Slide Rule Theory Notes
5 pages

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.

Multiplication and Division + Polish Your Skills

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.

  • Did you know that the inner scale is always time
Calculating Time

Calculating Time
10 questions

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.

Calculating Distance
5 questions

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

  • Finding Fuel Required
  • Finding Endurance
  • Finding Consumption rate

The Circular Slide Rule - Conversions
5 Lectures 10:40

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.


Converting Distances
10 questions

For Weight conversions we use the red indices against KG for kilograms and lb for pounds.


Converting Weights
5 questions

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.

Altitude Calculations Part 1
4 pages

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.

Altitude Calculations Part 2

Calculating Density Altitude
5 questions

Calculating True Altitude
5 questions

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.

True Air Speed (up to 300 knots)

Airspeed Calculations
10 questions

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.

Airspeed (above 300 knots)

Airspeed Calculations for TAS above 300 knots
5 questions

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.

Heading and Groundspeed

Calculating HDG and GS
10 questions

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.

Airline Pilot

Boeing 737 Airline Pilot and BSc Aviation Technology and Management Graduate, University of Leeds, United Kingdom. 

I create online courses on Udemy, in order to provide future and current pilots with an accessible, interactive and highly informative approach to training. I developed my passion for aviation from flying a Cessna 150 at a local airfield and since then have flown numerous powered aircraft and gliders. Completed my pilot training across Europe, flying in England, Sweden, Norway, Bulgaria and across other European countries during international flights. 

I am also a founder and manager of, author of a start-up airline business plan, co-author of an airline management training programme, have been awarded "The Dean of Engineering Excellence Scholarship" in all three years during university... I also enjoy extreme sports, especially windsurfing and climbing.
