The E6B calculator is a circular slide rule that pilots use to perform various calculations related to flight planning, navigation, and fuel consumption. It has been in use for more than 75 years and is still a required tool for many pilot training programs around the world. However, with the advancement of technology, many pilots now use electronic flight computers or aviation apps on their tablets or smartphones to perform the same calculations. These tools can provide faster and more accurate results, but they also require a reliable power source, which the E6B calculator does not. Ultimately, the use of E6B calculators is a personal preference for each pilot, but they are still considered an important tool for aviation calculations.
