Indicated Altitude 7,000 ft, Calibrated Airspeed (CAS) 120 kts, Temperature 5∘C5 raised to the composed with power C . Find True Airspeed (TAS). 5. Comprehensive Cross-Country Planning Exercise Use all skills to solve this realistic scenario: Route: KLAX to KSAN True Course: 155∘155 raised to the composed with power Distance: 90 NM Altitude: 6,500 ft Temperature: +5∘Cpositive 5 raised to the composed with power C Calibrated Airspeed (CAS): 130 kts Wind (from WX briefing): 270∘270 raised to the composed with power Calculate: Pressure Altitude (Assuming standard altimeter) True Airspeed (TAS) Wind Correction Angle (WCA) Groundspeed (GS) Total Time to Destination (EET) Total Fuel Required (Assuming 10 GPH) Answer Key for Practice
Your aircraft burns 8.4 GPH. How much fuel is consumed during a flight of 1 hour and 45 minutes?
Today's pilots have many resources for practice. Free online simulators like Gleim's Interactive E-6B allow hands-on practice in a browser. Mobile apps such as BasicFlightComputer animate the process step by step, and Sporty's offers an electronic E6B with a comprehensive user manual. The King Schools free E6B course provides structured video instruction.
The rate arrow (the large triangle on the inner scale) is your best friend here. Always set it to your speed to find time or distance. Exercise A: If your groundspeed is , how long will it take to travel Exercise B: You’ve been flying for 1 hour and 40 minutes at a speed of . How far have you traveled? Exercise C: 6.8 minutes . What is your groundspeed in knots? 2. Wind Correction & Groundspeed (The Wind Side)
Mastering the E6B flight computer is more than just a requirement for your pilot checkride; it is an exercise in developing precision, confidence, and a deeper understanding of the forces that govern your flight. Whether you prefer the tactile feedback of a manual "whiz wheel" or the efficiency of an electronic calculator, the key to proficiency is consistent practice. By working through these exercises, exploring digital tools, and continually challenging yourself with new scenarios, you will transform the E6B from a confusing gadget into an essential and trusted part of your pilot's toolkit.
The back of the manual E6B (or the "Wind" menu on electronic models like the Sporty’s Electronic E6B
Calculating how fast your aircraft moves over the ground and how long it will take to reach your destination are fundamental dead reckoning skills. Core Formula
This requires "dropping the dot" to find your Wind Correction Angle (WCA). The Setup: Set Wind Direction under the True Index Mark Wind Velocity up from the center grommet. True Course under the True Index. Slide the wind dot to your True Airspeed (TAS) Challenge: 160° at 20 knots . Your True Course is 270° (West) and your TAS is What is your Wind Correction Angle and Groundspeed? 3. Fuel Burn Calculations Fuel planning is critical for safety and completing a navigation log
Cruise flight is at 9,500 feet Pressure Altitude. OAT is -5°C. IAS is 140 knots. Find your TAS. Answer: 161 knots. Section 3: Wind Face Side Exercises
How to solve: Set the Speed Index to 135. Look at 14 on the inner scale. Read the outer scale. Answer: 31.5 NM.
Slide the grid card so your pencil mark rests directly on the line representing your TAS (125 knots). Read your Ground Speed under the central grommet.
Mark a dot 25 units up from the center grommet using the grid lines.
You are cruising at a pressure altitude of 7,500 feet. The outside air temperature (OAT) is +10°C. Your indicated airspeed (IAS) is 120 knots. E6B Steps:
