Pilot Flight Computers & Plotters

An E6B flight computer handles the core flight-planning math every pilot relies on: groundspeed and time en route, fuel burn, true airspeed, wind correction angle, and density altitude. The first decision is mechanical versus electronic, and both are FAA-legal for the written exam and the checkride.

Mechanical vs. electronic E6B: which should you buy?

• Mechanical (manual slide-rule) E6B: never needs batteries, can't fail on test day, and forces you to understand the relationships behind each answer. This is what most CFIs recommend a student own first. The ASA paper E6B is the low-cost starting point; the ASA aluminum E6B and the Jeppesen metal E6-B add durability that survives years in a flight bag. A round-window circular E6B is a compact alternative for the wind side.
• Electronic E6B: solves the same problems faster with fewer steps, ideal once you are working real cross-countries. The ASA CX-3 is accepted on FAA knowledge tests and adds timer, clock, and unit-conversion functions.

Checkride requirement

The E6B is required equipment for the FAA knowledge test and the practical test, so student pilots should buy early and practice often. Many examiners expect you to demonstrate the manual unit even if you also carry an electronic one.

Don't forget a plotter

Pilotage and dead-reckoning planning need a plotter to measure course and distance on a sectional. The ASA rotating plotter pairs with any E6B to complete your VFR nav-log workflow.
