ATC BASICS BLOCK 3 QUESTIONS WITH CORRECT ANSWERS GRADED A+

What is the formula used to calculate time/distance/speed fo an aircraft or of flight? - 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? - 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? - latitude for latitude and longitude, 1 degree is equal to how many minutes? - 60 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 longitude? - 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? - 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 - 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? Which type decreases? - 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 - 4.00 4.25 4.50 4.75 5.00 distance flown 274NM, time flown 2:00 hours. find the speed of the aircraft - 137 knots Distance flown 300 statute miles, speed of aircraft is 200mph, find the time interval flown - 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? - 1600Z What does a common wind report look like? how is it expressed and in what form? - 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? - 450NM 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."
