The E6B Circular Flight Computer combines high-quality construction with easy-to-read lettering to deliver the most efficient, accurate, and convenient manual flight computer availalble. Perform multiple calculations ranging from basic arithmetic and flight planning problems to complex in-flight computations.
The calculator side of the computer uses conventional slide rule procedures to solve for multiplication, division, and unit conversion and employs scales for performing time, speed, distance, rate, fuel consumption, altitude, airspeed, air temperature, and pressure pattern calculations.
The wind side of the computer provides a graphic method of solving problems and displaying the answers in a useful form. Use the wind side for simple addition and subraction problems and also to solve for true wind, winds in flight, true course and ground speed, true heading and true airspeed, and off-course correction calculations. The matte finish on the wind side of the calculator can be marked with a pencil during use, and easly wiped clean to allow input for the next problem.
The E6B Circular Flight Computer is a great tool to use during flight planning, flight training or studying, and may be used during FAA written knowledge exams. Pilots flying faster aircraft at higher altitudes will find this computer useful in gaining insight to the external atmospheric conditions and the effects they have on in-flight performance.
I needed a replacement for my Jeppesen CR-1,completely worn-out. This 6 plastic circular computer from ASA is more than I had hoped for. Large,Readable,dependable and no batteries required.
Bought for theory exams. Solid made good quality device, instruction though is not detailed. Excellent service from Aircraft Spruce - great price and fast delivery, thank you!
Id prefer a metal unit so that it wont get scratched up, but otherwise, perfect! Its big and easy to read (but not too big for one-handed use), and I far prefer the circular Jeppesen CR-* style like this to the traditional E6-B with the big rectangular plate underneath. You can do all the same calculations, but its just easier to hold and use, and looks better.
