Time, Latitude, Longitude, Magnetism Flashcards
factors to keep in mind while flying cross country? (4)
change in wind, weather & icing, fuel consumption, restricted airspace
what are the 4 methods of navigation?
pilotage- reference by landmarks
dead reckoning- pre determined vectors, wind, true airspeed, heading and ground speed
radio navigation- radio aids (VOR & NDB)
satellite navigation- satellite navs, transmitters & receivers
Zulu is also known as? and what is it?
Zulu is also known as Greenwich mean time GMT or UTC time
time zones in order from east to west canada ?
Newfoundland, Atlantic, Eastern, Central, Mountain, Pacific.
starts at UTC plus 3.5hrs then 4, 5, 6, 7, 8
unless daylight saving then each minus 1
longitude
(LONG) each meridian is one degree of longitude.
can go east or west for 180°. oppoaite side is called the international date line
prime meridian
0° longitude, UTC
latitude
(ladder) horizontal lines around earth
middle one is the equator
north pole is 90° north, south pole is 90° south
longitude and latitude are measured in?
degrees minutes the seconds
ex N 53° 18’ 35’’
S 113° 34’ 47’’
one minute of latitude is equal to ?
one degree of latitude is equal to ?
1NM
60NM
great circle
- shortest distance
- imaginary circle around earth
- crossing meridians at slightly different angles
rhumb lines
- not the fastest route
- easier for navigation
- crossing meridians at same angle
magnetic variation
true north is not the same at magnetic north
- poles are slightly off of the magnetic poles
agonic lines
magnetic lines with no magnetic variation from true north
isogonic lines
lines of equal magnetic variation
for eastern magnetic variation you should add or subtract from true track?
subtract
