6. PA 6,000 ft, Temp 10°C, CAS 95 kts → TAS? 7. PA 12,000 ft, Temp -5°C, CAS 145 kts → TAS? 8. PA 2,000 ft, Temp 30°C, CAS 80 kts → TAS? (High DA warning) Exercise 2.2: Finding Density Altitude Directly Goal: Know your aircraft’s takeoff performance.

When you sit for your FAA Knowledge Test, you will not fear the word problems. When you fly your first solo cross-country, you will correct for wind without second-guessing. And when the DPE (Designated Pilot Examiner) hands you a diversion scenario, you will smile, spin the wheel, and answer in 20 seconds.

Pressure Altitude = 8,500 ft. Temperature = +15°C. CAS = 110 kts. Find: TAS. E6B Method: Move the density altitude window so 8,500 ft aligns with 15°C. Read the "True Airspeed" correction: ~124 kts.

The E6B is not a relic; it is a thinking tool. Master the exercises, and you master the skies. Need more practice? Download our free E6B worksheet generator, or join our weekly pilot math webinar.

Groundspeed (GS) = 120 knots. Time = 1 hour 45 minutes. Find: Distance traveled. E6B Method: Rotate inner scale so 120 (outer) aligns with the index (60 minutes). Find 1:45 (105 minutes) on the inner scale. Read outer scale = 210 nautical miles.

However, owning an E6B doesn't make you a navigator; practicing with it does. Many student pilots fail their cross-country planning checkrides not because of poor flying skills, but because they fumble with time-speed-distance calculations or wind correction angles under pressure.
