Exercise 1
You fly 120 NM at a ground speed of 96 knots. How many minutes will the leg take?

Exercise 2
After 35 minutes of flight, you’ve covered 48 NM. What’s your ground speed?

Exercise 3
True Airspeed (TAS) = 125 knots. Leg time = 42 minutes. Distance flown?

Scenario: Burn rate = 9.2 GPH. You have 37 gallons usable. Headwinds force a lower ground speed.

Questions:

✅ Verified Answers:

Given:

Find TAS

✅ Verified Answer:
118 kt
E6B method: Set OAT (-5°C) opposite pressure altitude (6,500 ft). Find CAS (108) on inner scale; read TAS (≈118) on outer scale.

Before we dive into the exercises, a quick warning. If you grab a random PDF from a forum, the wind triangle solution might be off by 20 degrees. Practicing with bad data builds bad habits.

Characteristics of a verified exercise:

All exercises below have been verified using both a manual mechanical E6B (ASA CX-3) and the electronic Sporty’s E6B app. Discrepancies are within ±1 knot or ±1 degree.

As you climb higher, the air gets thinner. Your airspeed indicator lies to you because it is calibrated for sea level. You need to know how fast you are actually moving through the air molecules.

The Scenario: You are cruising at 8,000 ft. The outside air temperature (OAT) is +10°C. Your Indicated Airspeed (IAS) is 140 knots.

The Steps:

Result: You will see a number higher than 140 (likely around 155-160 knots). That is your True Airspeed. e6b+flight+computer+exercises+verified

This is the most intimidating exercise for new students, but it follows a logical process.

The Scenario: You are planning a flight. Your True Course (TC) is 270°. The Winds Aloft are 330° at 20 knots. Your True Airspeed (TAS) is 150 knots.

The Goal: Find your Wind Correction Angle (WCA) and Ground Speed (GS).

The Steps:

Why it matters: If you don't apply this correction, you will drift off course. If the dot is to the left, you correct left. If it's to the right, you correct right. Exercise 1 You fly 120 NM at a ground speed of 96 knots
