E6b Flight Computer Exercises Verified [better]

Find the time en route for a 45 nautical mile leg at a groundspeed of 112 knots.

The most frequent problems you will solve.

Calculating the heading needed to stay on course despite crosswinds.

Slide the grid up or down so that your pencil dot rests exactly on the arc line for your TAS (125 KT). Look at the center grommet to read your .

On the wind side, if the wind dot is on the left of the centerline, you subtract the correction from your course. If it is on the right, you add it. e6b flight computer exercises verified

Take the next step: Time yourself solving 5 wind problems in under 10 minutes. That is the FAA practical test standard. Fly safely, and keep the blue side up.

Your groundspeed is 115 knots. How long will it take to travel 78 NM? Verified Formula: Step-by-Step E6B Execution:

Set Pressure Altitude opposite OAT in the airspeed window. Look at Calibrated Airspeed (CAS) on the inner scale to find TAS on the outer scale.

Set 30°C against the pressure altitude of 5,000 ft in the window. Read the Density Altitude on the outer scale. ~6,700 ft. Exercise 6: Calculating True Airspeed (TAS) Scenario: Pressure Altitude: 9,000 ft Calibrated Airspeed (CAS/KIAS): 130 knots OAT: 5°C Steps: Set OAT (5°C) over 9,000 ft in the window. Find 130 on the inner scale. Read TAS on the outer scale. Verified Answer: ~150 knots KTAS. Verification Checklist for All E6B Exercises Find the time en route for a 45

Before diving into exercises, it's essential to understand the basic layout and functionality of the E6B. The device consists of several rotating scales, each with its own set of markings and labels. The most common scales found on an E6B include:

The dot is to the left of the center line (a left wind correction), showing a WCA of approx. -9° or -10°. GS: The dot is on the 113-knot line. Verified Answer: True Heading (TH): (approx). Groundspeed (GS): ~113 knots. Exercise 4: Complex Wind Correction Scenario: True Course (TC): 178° Wind Direction: 315° Wind Velocity: 35 knots True Airspeed (TAS): 150 knots Steps: Set wind direction (315) under the True Index. Mark 35 knots up from the center. Set TC (178) under the True Index. Slide mark to 150 knots (TAS). Verified Answer: Heading: 189°. Groundspeed: 127 knots. Part 3: Density Altitude and TAS

✅ Many E6Bs give 12° as one-step. Common teaching: turn 10° toward course.

Rotate the wheel to place wind direction (360°) under the True Index. Mark a point 20 units up from the center (grommet).

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.
