If you need to draw a course line on both sides of the chart, instructions are printed in the top left corner of the backside of a sectional chart.

Practical Knowledge Flight Computer Usage

Using your flight computer, calculate

  • the time to fly 78 NM at 117 knots.
  • the amount of fuel burned for a 1 hour 43 minute flight at 8.3 GPH.
  • the wind correction angle (WCA) and groundspeed given our true course is 113°, the winds aloft for the cruise altitude are 030° at 14 knots, and a planned TAS of 98 knots.
  • the expected IAS if our TAS is 105 knots, the pressure altitude is 6000 ft and the OAT is 10° C.
Study the Using the E6-B Flight Computer guide.
Decision Making and Risk Mgmt Identify the missed hazards and poor decisions in the accident report you analyzed.

Review weather briefing and weight and balance for flight.

Use the PAVE checklist to identify risks associated with the flight.

Research a general aviation accident that was stall/spin related in the NTSB accident database. Bring the accident report to the lesson.
