Formulas for the E6-B Air Navigation Computer


in stock


Formulas for the Air Navigation Computer is written for pilots and air navigators at all levels of experience from the novice to the professional. The book is self-help on how to use the E6-B Air Navigation Computer. An E6-B Air Navigation Computer is a circular slide rule with a wind slide on the reverse side. It is dedicated to performing all calculations related to pre-flight planning and in-flight air navigation. Every pilot has an E6-B Air Navigation Computer, which is supplied with a very brief instructional booklet when the E6-B is purchased. However, the booklet only covers a few basic formulas, and many more formulas are required for passing the pilot navigation exams at various levels and, of course, for all operational flying. Obtaining all these different formulas from various sources is time consuming, as this author has discovered over the years. They are not readily available in one book. This is the reason for writing Formulas for the Air Navigation Computer; it is a unique collection of air navigation computer formulas. The formulas are written as they appear when set up on the E6-B Air Navigation Computer. A full description on how to solve each formula is included, along with a worked example and also the methods for using the wind slide to calculate wind triangle and other navigational problems associated with the wind slide. The book is easy to follow by the novice pilot and a convenient reference source for the more experienced pilot. The book is complete with all the formulas a pilot of any level should need to know. It is laid out in a simple way with over 122 formulas and methods, covering Time, Speed & Distance, Air Speed, Altitude Navigation, VNAV, One-in-Sixty Rule, Wind triangle Calculations, Wind Finding methods, Fuel Calculations, Pressure Pattern Navigation and more.

Frank Hitchens


Frank Hitchens was born in Birmingham, England. At the age of seventeen years he joined the British Merchant Navy as a ship’s steward and travelled the world. He settled in New Zealand in 1965 and worked on the Inter Island ferries between Wellington and Lyttleton. While working on these ferries he joined the Wellington Aero Club and gained his Private Pilot Licence within six months of learning to fly and later, his Commercial Licence. He flew charter flights and joy rides for the club and enjoyed the challenges of cross-country flying and air navigation around New Zealand. He flew mostly single-engine light aircraft, including a flight in a rag-wing microlight and a few hours in a Boeing 737-800 flight simulator.
Marriage to his wife Deirdre in 1981 brought an end to his active flying. However, his love for aircraft and flying never waned. He continued his passion in the form of photographing planes and later, his technical interest in aeronautical subjects turned to writing. He has written several magazine articles published in New Zealand and also a book, Range & Endurance – Fuel-Efficient Flying in Light Aircraft published by Airlife/Crowood Press in 2007. Another book is also nearing completion.
