Look at the "60" index (the rate pointer) on the inner scale. It will point to roughly 11.5 on the outer scale, which translates to 115 knots . 2. Wind Correction and Groundspeed (The Back Side)
Rotate the bezel until the plotted dot is centered on the vertical line above the grommet.
. Often intimidating at first glance, this mechanical circular slide rule operates on basic principles of ratio and proportion to solve complex flight navigation problems without the need for batteries. Mastering the Scales: Time and Distance e6b flight computer exercises verified
The "calculator side" of the E6B uses a circular slide rule where the outer scale represents (or Fuel) and the inner scale represents Time . Problem A : You are flying at a groundspeed of and need to cover . How long will it take?
As you climb to higher altitudes, the air gets thinner. This affects both your aircraft's performance (density altitude) and the accuracy of your airspeed indicator (true airspeed). Getting these calculations right is critical for accurate flight planning. Look at the "60" index (the rate pointer) on the inner scale
Pedagogical design
Set the "60" index (the large black triangle) under 11 (representing 110 knots) on the outer scale. Find 18 on the outer scale; directly beneath it on the inner scale is 9.8 minutes . Fuel Consumption: This follows the same ratio as TSD. Wind Correction and Groundspeed (The Back Side) Rotate
The front side operates on a , aligning with the 60 minutes in an hour. The "60" index (often a large triangle) is your primary reference point.
Slide the grid so the center grommet rests on a clean line (e.g., 100).
