,What is the formula used to calculate time/distance/speed first double check if you are in MPH or KTS and make sure each factor is consistent
fo an aircraft or of flight?
D
S/T
d=distance
s=speed
t=time
What is a great circle? 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
latitude or longitude?
for latitude and longitude, 1 degree is equal to how many 60 minutes
minutes?
Rhumb line a line that runs across meridians at the same angle
1 nm is equal to how many feet 6,076.1 feet
1 SM is how many feet? 5,280ft
What is the conversion rate for NM to SM? NM x 1.15 = SM
and
SM x 0.87 = NM
Zulu time is based out of where? Green which England (prime merridean)
A time zone is established for every ____ degrees of 15 degrees
longitude?
When converting from LST to UTC (zulu), what is the time EASTERN STANDARD TIME +5 HOURS
conversion for each US time zone? CENTRAL STANDARD TIME +6 HOURS
MOUNTAIN STANDARD TIME + 7 HOURS
WHAT IS THE EFFECTS OF DAYLIGHT SAVINGS? 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 IAS corrected for temp and altitude
, Mach number 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? True airspeed is higher than indicated airspeed at higher altitudes
Which type decreases?
How are the following times represented in decimal form? 4.00
4+00 4.25
4+15 4.50
4+30 4.75
4+45 5.00
5+00
distance flown 274NM, time flown 2:00 hours. find the 137 knots
speed of the aircraft
Distance flown 300 statute miles, speed of aircraft is 1+30
200mph, find the time interval flown
An aircraft departs point A at 1100Z. point B is located 1600Z
370NM from point A. If the aircraft flies at a speed of
85mph, what will be its ETA?
What does a common wind report look like? how is it 04025
expressed and in what form?
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 450NM
of 40 knots. How far will the aircraft travel in 1 hour and 15
minutes?
true course the intended path of the aircraft over the earth's surface
track the actual path that the aircraft has flown over the earth's surface. "effected by wind,
etc."
Drift angle 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? TH = TC +/- WCA
WCA = wind correction angle
isogonic lines Imaginary lines which connect points of equal declination
variation the angular difference between true north and magnetic north
