- 1why we have season on earthThe earth is titlted on its axis at aprox 23,4 degrees
- 2Lines that divide the earthMeridians
Latitudes - 3What is a great circle?Any circle that divides the earth in two equal parts. Its projection will always give the shortes path to two pojnt on the surface of the earth
- 4What is a Rhumb lineIt's a line corssing all meridians of longitude at the same angle
- 5Notable parallelsArtic circle (66 N)
Tropic of cancer(23 N)
Equator (0)
Tropic of Capricorn (23 S)
Antartic circle (66 S) - 6After how many degrees of earth rotation hour cangesEvery 15 degrees to the east add one hour
every 15 degrees to the west subtract one hour - 7In time prospective , when does the day starts/ends30 min before sunrise
30 min after sunset - 8What is True course (TC)The course measured on the chart
Direction measured by reference to the true north on the chart - 9What is true heading (TH)It's the direction at which the nose of the aircraft is pointing
- 10What is Variation?Variation is the angle between the true north(TN) and magnetic north (MN)
- 11What are isogonic lines? agonic line?Line that connect the surfaces with the same variation
Agonic line is the line that connects 0 variation - 12Three aspect that must be corrected for navigationMagnetic variation
compass deviation
win correction - 13how to correct variation? to get MHIf variation is to the east we have to subtract
if variation is to the west
we have to add
"West is best East is least" - 14equation of heading and varTH = MH + VAR
in this case East is +
West is - - 15what is deviation?When compass reading is deflected
by circuits ecc
unique to each aircraft - 16what is compass headingMagnetic heading corrected by the deviation
- 17What are isoclinic lines?Lines that join points of equal magnetic dip
- 18what is trackCombination of aircraft and wind movement
- 19convert knots to mphmph= knotsx1.15
- 201nm = how many m1852
- 211nm = feet5280
- 22the distance between 1 * of longitudine on equator111km
- 23equator lenght21600NM
- 24different type of projections of the earthmathematicly generated projections
conical projections
cilindrical projection
azimutal projections - 25what is pilotage?Pilotage is navigation by reference withlandmarks and checkpoints
- 26what is navigation by dead reckoning?is based on ime, airspeed, distance, direction
- 27how to corect deviation of track with a simle ruleThe 1 in 60 rule!
track error = (distance off track/ distance traveled)*60
closing angle = (distance off track/ distance to go)*60 - 28radio navigation systems for VFRVHF omnidirectional range (VOR)
