This is where most students fail. The wind triangle involves four variables: True Course (TC), True Airspeed (TAS), Wind Direction & Speed, and resulting Ground Speed (GS) & Wind Correction Angle (WCA).
You traveled 45 NM in 20 minutes. What is your groundspeed? Steps:
To achieve true mastery, consistency is key. Here is a suggested roadmap: e6b flight computer exercises verified
Slide the wind mark to align with your True Airspeed (TAS) on the grid. The grommet then reveals your Ground Speed , while the wind mark's horizontal displacement shows the Wind Correction Angle (left or right). Practical Exercises for Verification Standard exercises used in Private Pilot (PPL) Ground School
Slide the grid until the mark rests on the 100-knot airspeed arc. Read the groundspeed under the center grommet. This is where most students fail
: Similar to speed, set the fuel burn rate (gallons per hour) at the speed index to determine total fuel burned for a specific flight duration. Wind Correction & Groundspeed : Set the wind direction under the "True Index." Mark the wind velocity up from the center grommet. Set your True Course under the True Index.
The core of E6B work involves the 60:1 proportion used to compute time, speed, or distance when any two are known. Use the following exercises to master this fundamental skill. What is your groundspeed
The Learn to Fly blog features a "CFI Brief" specifically on enroute questions requiring an E6B, which closely resemble what you will find on the FAA knowledge exam. These exercises cover:
Why practice these specific exercises? Because in the air, you cannot trust your gut.
A rotating disk used to represent time (minutes/hours) or calibrated airspeed.
You have been cruising at a groundspeed of 95 KT for 38 minutes. How far have you traveled? E6B Steps: Align the 60 pointer with 95 on the outer scale. Locate 38 on the inner scale. Read the distance directly above 38 on the outer scale. Verified Answer: 60.2 NM. Category 2: Fuel Consumption Calculations
