E6b Flight Computer Exercises Verified May 2026

1. Basic Rules for Verified Solutions

To ensure your E6B results are accurate:

• Always check the “10” index (the large triangle or diamond on the inner scale) – it often represents 10, 100, 1000.
• Use the correct window:
  • Rate window (triangular cutout) → for speed, distance, time.
  • Temperature/pressure window → for density altitude, true airspeed (TAS).
• Round conservatively – FAA answers are within ±2% usually.

5. Fuel Consumption

Exercise 5.1

• Fuel burn rate: 9.5 GPH
• Time: 3 hr 20 min = 200 min
• Find: Total fuel needed

Place 9.5 over 60. Opposite 200 min → fuel.

Verified:
31.7 gallons

Exercise 5.2

• Fuel used: 45 gal
• Time: 4 hr 30 min = 270 min
• Find: Fuel flow (GPH)

Place 45 opposite 270 min. Read fuel flow over 60.

Verified:
10.0 GPH

2. Distance, Speed, Time – True Airspeed (TAS)

Problem:
Fly 120 NM in 48 minutes. What is TAS?

Solution:

• Set 48 on inner scale over 120 on outer scale.
• Over 60 (inner) → read outer: 150 kts.

✅ Verified: 120 NM / (48/60 hr) = 150 kts.

1. Fuel & Time – “How Long Can I Fly?”

Problem:
You have 28 gallons usable. Burn rate = 9.5 GPH. How many hours/minutes endurance?

Solution (E6B):

• Set 9.5 on outer scale over 60 (minutes) on inner scale.
• Find 28 on outer scale → read inner scale: 176 minutes → 2 hr 56 min.

✅ Verified: 28 ÷ 9.5 = 2.947 hrs × 60 = 176.8 min. e6b flight computer exercises verified

The "Verified" Guide to E6B Flight Computer Exercises

The E6B is two tools in one: a calculator (slide rule face) and a vector plotter (wind side). Most errors occur not because the math is hard, but because the setup is wrong.

Use this guide to perform the exercise, then use the "Verification Step" to confirm your answer is correct.

Part 3: Wind Correction & True Heading (The Tricky Part)

Wind problems are the most failed portion of the E6B oral exam. Verified practice is non-negotiable.

Exercise 4.2 – True Airspeed (TAS)

Problem:
Pressure altitude = 8000 ft, OAT = -10°C, Indicated airspeed (CAS) = 120 kts. Find TAS. Always check the “10” index (the large triangle

Steps:

1. Set OAT (-10°C) over pressure altitude (8000 ft).
2. Find CAS (120) on inner scale.
3. Read TAS on outer scale.

Verified answer: ~139 kts

Exercise 1: Time, Speed, and Distance

• Given: Distance = 200 NM, Speed = 120 KT
• Find: Time = ?
• Solution: Set the outer scale (STATUTE) to 120 KT, then align the inner scale (TIME) to 200 NM. Read the time: 1 hour 40 minutes.
