Pilots are constantly making calculations, whether it’s estimating fuel burn, working out a crosswind component, calculating time enroute, or applying the famous 1-in-60 rule. While electronic flight bags and cockpit technology are invaluable tools, there is still immense value in being able to perform quick and accurate mental calculations when it matters most.
Pilot.ie is pleased to announce the arrival of Mental Math for Pilots (Third Edition) by Ronald D. McElroy, now available for €28.95.
Written by a highly experienced airline, military, and FAA test pilot, this practical guide teaches pilots how to solve common aviation calculations quickly and efficiently without reaching for a calculator, flight computer, or even a pencil and paper. Mental arithmetic remains an essential skill throughout a pilot’s career. From student pilots preparing for their first solo flight to experienced airline pilots facing time-critical decisions in the cockpit, the ability to make accurate calculations can improve situational awareness and decision-making.
The book covers a wide range of practical aviation topics, including:
- Fuel planning
- Temperature conversions
- Reciprocal headings
- Turn radius calculations
- Crosswind components
- Time, speed and distance problems
- True airspeed calculations
- The 1-in-60 navigation rule
- Numerous additional cockpit shortcuts and techniques
According to the publisher, the techniques presented are designed to be simple, practical, and immediately applicable in real-world flying situations, helping pilots stay ahead of the aircraft and make better-informed decisions.
In addition to its cockpit applications, Mental Math for Pilots has become a popular resource for pilots preparing for airline interviews and aptitude assessments. Many airline recruitment processes include numerical reasoning and aviation-related calculation exercises, making mental maths proficiency a valuable advantage.
Whether you’re pursuing a commercial pilot career, preparing for an airline assessment day, or simply looking to sharpen your aviation knowledge, this book offers a structured approach to mastering the calculations pilots encounter every day.
