AVIA 1084 Navigation Notes

Week 10: Flight Planning Overview

  • Key Flight Plan Route: CYXU - CYZR - CYQG - CYXU

Today's Agenda

  • Check homework plan for:   - CYZR to CYXU   - CYZR to CYQG   - CYQG to CYXU

Flight Planning Details

Route: CYZR - CYXU

  • General Weather Analysis:   - GFA indicates no significant weather for the area.   - Terminal Aerodrome Forecasts (TAFs) for London and Sarnia:     - Sky forecast: broken at 8,000 feet.     - No precipitation expected.     - Winds generally from 310 degrees at 10 knots.   - METARs for London and Sarnia:     - The observations are consistent with TAFs.     - Average altimeter setting: 30.12 inHg.     - Average temperature: +8°C.     - Wind at altitude: 305 degrees at 16 knots (from flight data).

  • Cruise Altitude: 5,500 feet.     - Expected temperature: -1°C.

  • Compass Deviation Adjustment: Add +1° to compass heading.

  • Set Heading Point:   - Wyoming during flight.

  • Ground Speed Check Points:   - Watford   - Strathroy

Specific Notes and Calculations

  • Start/Taxi/Run-up/Climb Summary for CYZR - Georgia:   - Ground Speed Checkpoints for reference.   - Notable checkpoints include: Wyoming, Watford, Strathroy etc.

Route: CYZR - CYQG

  • Set Heading Point: Brigden, then direct flights to:   - Tilbury   - Windsor Airport (CYQG)

  • Ground Speed Checkpoints for the route:   - Wallaceburg   - Tilbury   - Belle River

Traffic Warnings

  • Caution advised for:   - Heavy river traffic in climb/descent from surface to 3000 feet ASL.

  • Riverside Descent Area: Consult flight supplement for detailed navigation, especially around Lake St. Clair.

Flight Parameters and Operational Data

For CYZR to Tilbury

  • Winds: 310 degrees at 12 knots at 3000 feet:   - Requested cruising altitude: 4,500 feet.   - Pressure altitude based on altimeter setting (30.12): 4316 feet.

Temperature and Density Altitude Calculations

  • At 4,500 feet CYZR - Tilbury route:   - Temperature: 1°C (based on lapse rate from surface).   - Density Altitude Calculation: 3662 feet.

Additional Leg Information

  • Heeding altitude considerations for the segment:   - From Tilbury to CYQG, descend to 2,500 feet to remain clear of Detroit TCA.   - Recalculated Pressure Altitude: 2316 feet based on established rates.

Wind Calculations

  • Wind at 4500 feet:   - Average speed and direction: (3112 at 3000 feet, 3019 at 6000 feet).   - Interpolated estimates:     - Direction: (310 + 300)/2 = 305 degrees.     - Speed: (12 + 19)/2 = 15.5 knots (rounded to 16 knots).

Cruising Altitude Adjustments

  • Current altitudes:   - CYZR to Brigden 4,500 ASL   - Tilbury to CYQG 2,500 ASL

Fuel Calculations for Climb Scenarios

  • Considerations for Aircraft Weights:   - 1 lb fuel = 1 ton of aircraft for each 1000 feet of climb.   - Max takeoff weight of DA20: 1,764 lbs.   - Expressed in tons for calculations: 1764/2000 = 0.88 tons.   - Total Climb Fuel Calculations:     - For climbing total of 3,600 feet results in fuel needs of 3.17 lbs or approximately 0.5 gallons.

Time and Fuel Required Per Leg

  • CYZR to Brigden: Distance 11 NM, Time 0:06 hours.

  • Brigden to Tilbury: Distance 34 NM, Time 0:18 hours.

  • Tilbury to CYQG: Distance 23 NM, Time 0:14 hours.

  • Total Estimated Time is 5.6 gallons for planned trajectory with 1-hour reserve taken into account.

Final Points

  • A reference note confirms the completion of navigation logs required for cross-country travel essential for the Private Pilot license.

  • Prepare for the following week:   - Flight Planning Quiz focused on CX3 for computing headings, ground speeds, time and fuel, etc.   - Topics include Radio Navigation subjects and relevant theory.
