ATC BASICS BLOCK 3
What is the formula used to calculate time/distance/speed fo an aircraft or of flight? -
answer first double check if you are in MPH or KTS and make sure each factor is
consistent
D
S/T
d=distance
s=speed
t=time
What is a great circle? - answer the equator is the only one, formed on the surface of a
sphere by the intersection of a plane that passes through the center of the sphere; an
arc of which connecting two terrestrial points constitutes the shortest distance on the
earth's surface between them
when stating or writing coordinates, what comes first, latitude or longitude? - answer
latitude
for latitude and longitude, 1 degree is equal to how many minutes? - answer60 minutes
Rhumb line - answera line that runs across meridians at the same angle
1 nm is equal to how many feet - answer6,076.1 feet
1 SM is how many feet? - answer5,280ft
What is the conversion rate for NM to SM? - answerNM x 1.15 = SM
and
SM x 0.87 = NM
Zulu time is based out of where? - answerGreen which England (prime merridean)
A time zone is established for every ____ degrees of longitude? - answer15 degrees
When converting from LST to UTC (zulu), what is the time conversion for each US time
zone?
,WHAT IS THE EFFECTS OF DAYLIGHT SAVINGS? - answerEASTERN STANDARD
TIME +5 HOURS
CENTRAL STANDARD TIME +6 HOURS
MOUNTAIN STANDARD TIME + 7 HOURS
PACIFIC STANDARD TIME + 8 HOURS
ALASKA STANDARD TIME +9 HOURS
HAWAII STANDARD TIME + 10 HOURS
IF DAYLIGHT SAVINGS TIME IS IN EFFECT, SUBTRACT 1 HOUR FROM
CONVERSION
NOTE: DST starts at 2 AM the seoncd sunday in march and ends at 2am on the first
sunday in november
TRUE AIRSPEED - answerIAS corrected for temp and altitude
Mach number - answerratio of true airspeed to the speed of sound, expressed in
decimal form
521 knots is the speed of sound
What type of speed increases as altitude increases?
Which type decreases? - answerTrue airspeed is higher than indicated airspeed at
higher altitudes
How are the following times represented in decimal form?
4+00
4+15
4+30
4+45
5+00 - answer4.00
4.25
4.50
4.75
5.00
distance flown 274NM, time flown 2:00 hours. find the speed of the aircraft - answer137
knots
Distance flown 300 statute miles, speed of aircraft is 200mph, find the time interval
flown - answer1+30
An aircraft departs point A at 1100Z. point B is located 370NM from point A. If the
aircraft flies at a speed of 85mph, what will be its ETA? - answer1600Z
, What does a common wind report look like? how is it expressed and in what form? -
answer04025
040 = the heading it is approaching from
25 = the speed in knots
040 is the true angle, not the magnetic angle
An aircraft has a true airspeed of 320 knots and a tailwind of 40 knots. How far will the
aircraft travel in 1 hour and 15 minutes? - answer450NM
true course - answerthe intended path of the aircraft over the earth's surface
track - answerthe actual path that the aircraft has flown over the earth's surface.
"effected by wind, etc."
Drift angle - answerwhat any free object will do as the air moves downwind with the
speed of the wind
Difference between true course and track
What is the formula for True heading? - answerTH = TC +/- WCA
WCA = wind correction angle
isogonic lines - answerImaginary lines which connect points of equal declination
variation - answerthe angular difference between true north and magnetic north
agonic line - answerline of 0
What is the formula to calculate the magnetic heading? - answerMH = TH +/- VAR
wind in weather reports and forecasts are given in reference to... - answertrue north
What is the saying to help remember whether to add or subtract when calculating TH,
MH, CH? - answereast is least (-)
west is best (+)
What is the formula to calculate compass heading? - answerCH = MH +/- DEV
What are some of the things that can cause errors in the magnetic compass? -
answerelectrical circuits
engine
