  6. Waldseemuller’s Map of 1507

  7. CHARTS • Graticule - grid over the globe made up of circles • Parallels of Latitude • Meridians of Longitude • Prime Meridian • International Date Line

  8. ADIS ABABA LONDON GREENLAND VANCOUVER CHARTS • Great circle or great circle route will be a circle that cuts through the center of the globe • Small circles – all parallels of latitude except the equator • All meridians are great circles

  9. MEAN TIME • Time between two transits of a meridian is apparent solar day – varies • Mean sun travels at assumed constant speed • Mean solar day same all year • 360o passes in 24 hours so 24 hr = 360o 1 hr = 15o 1 min = 15’ 1 sec = 15” • Local mean time set to mid-meridian 15o

  10. Latitude 0o to 90o from equator to poles Degrees 0 Minutes ’ Seconds ”

  11. Longitude 0o to 360o from prime meridian Degrees 0 Minutes ’ Seconds ”

  12. Meldrum Bay is at 450 55 ’ 35 ” lat 830 07 ’ 10 ” long

  13. One nautical mile is 6080 feet, a statute mile is 5280 A nautical mile is one minute of arc along a great circle 6080 feet to 5280 feet 70 to 60 1.15 to 1 1 knot is slighter faster than 1 mph 60 knots = about 70 mph

  14. Aircraft: Cessna 150 C-GULP White with Red/Orange trim • Owner: Yourself c/o Kingston Federal Pen, Kingston, ON • Radio equipment: 1 NAV/COM, 1 Transponder with Mode C, 1 ADF receiver • ELT: Pointer Sentry Fixed ELT • Route: CYGK (Kingston) Direct CYOW (Ottawa). Set heading point will be overhead Kingston • Power Setting: Closest to 60% at your cruising altitude of 5,500’ ASL • Weather: Assume Standard temperature, Altimeter setting 29.92” Wind at 5,500 ASL forecast to be 220°T at 18 knots • Pilot Licence: PA321123 • Allow 6 minutes at cruise power for circuit before landing at Ottawa. For start, run-up, takeoff and climb, allow fuel as indicated on the charts. Proposed departure time is 0200 EDT. • Complete a flight log and a flight plan for the proposed flight.

  15. Measure track at mid meridian

  17. MAG vs COMPASS HEADING • FROM PLANNING LOG TO FLIGHT LOG INCLUDE DEVIATION (From the magnetic meridian)

  19. Cross Country #2 • Twenty two (22) minutes after setting heading, you pinpoint your position over the town of Perth (N44°54’ W76°15’) • What is your groundspeed? • What winds are you encountering? • What magnetic heading will take you to Ottawa? • When will you be overhead Ottawa?

  20. 1414 042 1414 042 set heading 1436 042 PERTH 43nm in 22 (E6B 76/39) • Twenty two (22) minutes after setting heading, you pinpoint your position over the town of Perth (N44°54’ W76°15’)

  21. 1414 042 set heading 1436 042 PERTH 43nm in 22 (E6B 76/39) 1453 117 • What is your groundspeed? • When will you be overhead Ottawa?

  22. 1414 042 1414 042 set heading 1436 042 PERTH 43nm in 22 (E6B 76/39) 1453 117 Drift left10o open • What winds are you encountering?

  23. Wind Calculation 1 –actual true track 021o (031o – 10o drift left) and gs 117k

  24. Wind Calculation 2 - tas97k (mag hdg 029o – mag trk 021o ) from 8o right

  25. Wind Calculation 3 – 170o @25

  26. 1414 042 1414 042 set heading 1436 042 PERTH 43nm in 22 (E6B 76/39) 1453 117 065 Drift left10o open +13o close • What magnetic heading will take you to Ottawa?
