E6b Flight Computer Exercises Verified !!better!! Here

Mastering the E6B flight computer (often called the "whiz wheel") is a rite of passage for every student pilot. While digital apps are convenient, the manual E6B remains a critical, fail-safe tool approved for FAA written exams. Proficiency requires consistent practice with verified exercises to ensure your calculations for ground speed, fuel burn, and wind correction are pinpoint accurate. Core Calculations: The Calculator Side

The front of the E6B operates on a 60:1 ratio, leveraging the fact that there are 60 minutes in an hour.

Time, Speed, and Distance (TSD): The most frequent problems you will solve.

Exercise: At a ground speed of 110 knots, how long will it take to travel 18 NM?

Solution: 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.

Exercise: Your aircraft burns 8.4 gallons per hour (GPH). How much fuel is used in 45 minutes?

Solution: Align the "60" index under 8.4 on the outer scale. Find 45 on the inner scale; the outer scale will show 6.3 gallons.

Conversions: The E6B easily converts between nautical miles (NM), statute miles (SM), and kilometres (KM) using specific index marks. Mastering the Wind Side

The back of the E6B is used for wind vector solutions—determining how wind affects your speed and course.

The E6B flight computer, often called the "Whiz Wheel," is a manual slide rule used by pilots to solve complex navigation and performance problems without batteries. Mastering it is essential for passing the FAA Private Pilot Knowledge Test 🧭 Wind Side Exercises (Wind Correction & Ground Speed) The wind side is used to find your True Heading (TH) Ground Speed (GS) when you know the wind and your True Airspeed (TAS). Exercise 1: Finding Ground Speed & Heading Conditions: True Course (TC) 090°, TAS 120 kts, Wind 180° at 25 kts. Rotate the True Index to 180° (wind direction). Mark a dot 25 units from the center grommet. Rotate the True Index to 090° (your course). Slide the wind dot onto the 120 arc (your TAS). Verify Result: Ground Speed: Read at the center grommet (~117 kts). Wind Correction Angle (WCA): See where the dot falls left/right of center (~12° Right). True Heading: 🔢 Calculator Side Exercises (Speed, Time, Distance)

The calculator side uses a logarithmic scale to solve "60-to-1" ratio problems. The Large Black Triangle (60 Rate) on the inner scale represents 60 minutes (1 hour). Exercise 2: Estimated Time En Route (ETE) How long to fly 150 NM at a Ground Speed of 135 kts? Align the "60 Rate" triangle on the inner scale with (representing 135 kts) on the outer scale. (representing 150 NM) on the outer scale. Read the answer directly below it on the inner scale. Verify Result: ~67 minutes (1 hour and 7 minutes). Pilots of America Exercise 3: Fuel Consumption

The E6B flight computer (or "Whiz Wheel") remains a foundational tool for pilots, functioning as a circular slide rule to solve complex navigation problems. It is still FAA-approved for written exams in both its traditional mechanical and modern electronic forms.

Below are verified exercise examples and a breakdown of how to use the device to solve them. 1. Time, Speed, and Distance (The Front Side)

The front side operates on a 60-to-1 ratio, aligning with the 60 minutes in an hour. The "60" index (often a large triangle) is your primary reference point.

Example Exercise: Calculate groundspeed if you fly 13 NM in 6.8 minutes.

Step: Align the distance (13) on the outer scale with the time (6.8) on the inner scale.

Result: 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)

The back side uses a sliding card and a rotating azimuth to solve wind vector problems.

Example Exercise: Find your Wind Correction Angle (WCA) and Groundspeed (GS).

Given: Magnetic Course 328°, Wind 270° at 5 knots, True Airspeed (TAS) 112 knots.

Set Wind: Rotate the azimuth to the wind direction (270°). Use a pencil to mark the wind speed (5 units) up from the center grommet. Align Course: Rotate the azimuth to your course (328°).

Adjust TAS: Slide the card so the wind dot rests on your TAS line (112 knots). Mastering the E6B flight computer (often called the

Read Result: The grommet now shows your Groundspeed, and the dot's horizontal offset indicates your WCA in degrees. 3. Density Altitude Calculation

Density altitude is critical for determining aircraft performance in different atmospheric conditions.

  • True Airspeed (TAS): 110 kt
  • Wind: 040° at 25 kt
  • Find: Wind Correction Angle (WCA), True Heading (TH), Ground Speed (GS)

Solution (E6B slide rule method):

3. Exercise Set 2: Fuel Consumption

Exercise 2.1 – Gallons per Hour

Problem:
Burn 36 gallons in 4 hours. GPH?

Steps:

  1. Set 36 on outer scale over 4 hours (inner scale, but convert 4:00 = 240 min? Wait – careful: For fuel rate, treat hours on inner scale as hours directly if using 1-hour index. Easier: Place 36 over 4 (inner). Read GPH at the “1” (or 10) index on inner scale.
    Better E6B method:
    Set 36 outer over 4 inner (hours). Read outer over inner 1 hour index (arrow at 60 min if minutes scale, but for hours use 1 on inner).
    Actually: Align 36 outer with 4 inner (hours). Over the “1” (1 hr) on inner, outer reads 9.

Verified answer: 9 GPH
