Best Flight Computers Reviewed (E6B, CX-2, CX-3, CR-3)

If you’ve ever wondered about the types of computers used by airline pilots, wonder no more. Just like the rest of us, pilots rely on computers for a variety of purposes, and this includes the analog flight computers that are essentially circular slide rules used both in flight training and in the actual flying of the plane. Although analog in design, flight computers are used on the ground before takeoff and while the plane is in the air, making them very valuable devices a pilot can’t live without.

Flight Computer Knowledge

Metal E6B Flight Computer
Editorial Team Metal E6B Flight Computer

What Is a Flight Computer?

A flight computer is used both before takeoff and while the plane is in the air, and its uses include calculating fuel burn, time en route, and wind correction, while the plane is still on the ground; and calculating ground speed, updating the estimated time of arrival, and estimating fuel burn, while the plane is in the air. You can also use a flight computer to determine how much the wind affects the plane’s course and speed.

Flight computers are commonly known as the E6B, CRP-5, or the CR2 and CR3. In German, it is frequently called the Dreieckrechner.

Electronic Versus Manual Flight Computers

Most flight computers are analog computers, which may be considered unusual for the 21st century. There are, however, electronic versions of flight computers that are still allowed to be used in FAA exams. However, pilots are still required to know how to use an analog computer because that is the type usually found in the plane itself.

How to Use a Flight Computer

Flight computers have various functions, including a few basic functions that all pilots need to learn how to do. These include the rotating slide rule side, which involves three scales that you can line up to calculate things; lining up one number with another one to get a certain answer, including determining your ground speed; and the wind side, or back side, which has a rotating scale and a reference point found in the center of a circle.

Best of all, specific directions for using a manual computer are usually printed on the device itself, making it easier to determine how to use it.

Who Invented the Flight Computer?

Flight computers were invented by Philip Dalton, a Naval Reserve pilot; and P.V.H. Weems, and they have gone through various revisions through the years. The Model B, developed in 1933, came with corrections for True Airspeed (TAS) and Altitude. In 1936, the device was modified again, followed by several other revisions until the E6B was developed. The E6B was used during World War II, when over 400,000 of them were manufactured and used by the military.
