A

56 days

24
Q

what is the CAP, what information does it give us and how often updated

A

Canada air pilot
IFR arrival and departure procedures, noise abatement procedures
56 days

25
Q

what is the WAS and how often updated

water aerodrome cupplement
annually

26
Q

what is the DAH, what does it tell us and how often updated

A

designated airspace handbook
airspace and classes in canada
56 days

27
Q

what is the DAH, what does it tell us and how often updated

A

designated airspace handbook
airspace and classes in canada
56 days

28
Q

what is the lambert conformal conic projection

A

great circle
shortest distance

29
Q

i’m using a VNC, am i flying a consitent heading from point A to B?

A

no a VNC is great circle lines, so you’ll be changing heading during your route
change heading 2º for every 3º of longitude
flying east the 2º is added
flying west the 2º is subtracted

30
Q

what is a mean solar day

A

the pass of the sun over a specific meridian of longitude (24h or 360º longitude/day)

31
Q

if UTC is 1am, what is the local time in ontario?

A

UTC to EST is -5h so 8pm the day before

32
Q

what is the time difference between UTC and CST?

A

-6h

33
Q

when does night officially begin,

A

after evening civil twilight ends and before morning civil twilight begins

34
Q

does civil twilight count as day or night to Tc

A

day

35
Q

what is the standard meridian for the CST time zone

A

90ºW

36
Q

1º = _____ mins

A

4 mins

37
Q

i start with knowing my true track, what must i account for to know my true heading

A

wind correction angle

38
Q

i know my true heading, what must i account for to know my magnetic heading

A

magnetic variation

39
Q

i know my magnetic heading, what must i account for to know my compass heading

A

deviation

40
Q

the double track error method for getting back to your desired track only works for

A

first half of flight

41
Q

what is DR navigation

A

dead reckoning
flying with time, distance and direction only

42
Q

what is pilotage

A

flying to destination using visual landmarks only

43
Q

what is air position vs ground position

A

ground position = point on the earth directly underneath the plane

air position= where the plane would be after a period of time based on heading and true airspeed (where would i be if no winds)
