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

9
CHARTS
ADIS ABABA LONDON GREENLAND VANCOUVER
  • 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

10
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

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

  • 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 220T 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.

Cross Country 2
  • Twenty two (22) minutes after setting heading,
    you pinpoint your position over the town of Perth
    (N4454 W7615)
  • What is your groundspeed?
  • What winds are you encountering?
  • What magnetic heading will take you to Ottawa?
  • When will you be overhead Ottawa?
