E6b Flight Computer Exercises Verified
Wind problems are the most failed portion of the E6B oral exam. Verified practice is non-negotiable.
Problem: You fly 84 nautical miles (NM) in 28 minutes. What is your ground speed (GS)?
Solution:
Problem: Airport elevation = 3,500 ft. Altimeter setting = 29.85 inHg. Temperature = +28°C. Find density altitude. e6b flight computer exercises verified
Solution (E6B altimetry side):
Verification: Using formula: DA ~ PA + 120×(OAT - ISA temp at PA). ISA at 3,570 ft ≈ 9.5°C. Difference = 18.5°C. 120×18.5 = 2,220 ft. 3,570 + 2,220 = 5,790? Slight variation due to pressure correction. E6B verified within 50 ft of electronic calculator.
Fuel planning is where unverified exercises crash (literally, in the logs). Here are verified examples. Wind problems are the most failed portion of
Problem:
You fly perpendicular to a VOR radial for 2 minutes and note 10° bearing change. Time to station?
Solution (E6B):
✅ Verified: 60 × (time between bearings) / (bearing change) = 60 × 2 / 10 = 12 min. Verification: Using formula: DA ~ PA + 120×(OAT
Why practice these specific exercises? Because in the air, you cannot trust your gut.
If you are in the cockpit and your GPS fails, and you calculate a Ground Speed of 150 knots when your GPS was just showing 110 knots, you must know instantly if your math is wrong. By practicing "verified" exercises with known answers, you build a library of mental benchmarks. You develop a "reality check" that tells you:
Problem:
True course (TC) = 090°, TAS = 110 kts, Wind = 030° at 20 kts. Find wind correction angle (WCA) and groundspeed.
Steps (using E6B wind side):
