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? - ANSWER 60
minutes
Rhumb line - ANSWER a line that runs across meridians at the same angle
1 nm is equal to how many feet - ANSWER 6,076.1 feet
1 SM is how many feet? - ANSWER 5,280ft
What is the conversion rate for NM to SM? - ANSWER NM x 1.15 = SM
and
SM x 0.87 = NM
Zulu time is based out of where? - ANSWER Green which England (prime merridean)
A time zone is established for every ____ degrees of longitude? - ANSWER 15
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? - ANSWER EASTERN
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 - ANSWER IAS corrected for temp and altitude
Mach number - ANSWER ratio 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? - ANSWER True 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 - ANSWER 4.00
4.25
4.50
4.75

distance flown 274NM, time flown 2:00 hours. find the speed of the aircraft - ANSWER
137 knots
Distance flown 300 statute miles, speed of aircraft is 200mph, find the time interval
flown - ANSWER 1+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? - ANSWER 1600Z
, What does a common wind report look like? how is it expressed and in what form? -
ANSWER 04025
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? - ANSWER 450NM
true course - ANSWER the intended path of the aircraft over the earth's surface
track - ANSWER the actual path that the aircraft has flown over the earth's surface.
"effected by wind, etc."
Drift angle - ANSWER what 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? - ANSWER TH = TC +/- WCA
WCA = wind correction angle
isogonic lines - ANSWER Imaginary lines which connect points of equal declination
variation - ANSWER the angular difference between true north and magnetic north
agonic line - ANSWER line of 0
What is the formula to calculate the magnetic heading? - ANSWER MH = TH +/- VAR
wind in weather reports and forecasts are given in reference to... - ANSWER true north
What is the saying to help remember whether to add or subtract when calculating TH,
MH, CH? - ANSWER east is least (-)
west is best (+)
What is the formula to calculate compass heading? - ANSWER CH = MH +/- DEV
What are some of the things that can cause errors in the magnetic compass? -
ANSWER electrical circuits
