CHARTS Graticule - grid over the globe made up of circles Parallels of Latitude Meridians of Longitude Prime Meridian International Date Line
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 ADIS ABABA LONDON GREENLAND VANCOUVER
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 360 o passes in 24 hours so 24 hr = 360 o 1 hr = 15 o 1 min = 15’ 1 sec = 15” Local mean time set to mid-meridian 15 o
Latitude 0 o to 90 o from equator to poles Degrees 0 Minutes ’ Seconds ”
Longitude 0 o to 360 o from prime meridian Degrees 0 Minutes ’ Seconds ”
Meldrum Bay is at ’ 35 ” lat ’ 10 ” long
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 to 1 1 knot is slighter faster than 1 mph 60 knots = about 70 mph
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: PA 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.
