To get a complete weather briefing for the planned flight, the pilot should request what type of briefing?
You should request a standard briefing any time you are planning a flight and you have not received a previous briefing.

(Refer to Figure 25, area 5.) The navigation facility at Dallas-Ft. Worth International (DFW) is a
Reference FAA Legend 1. There is a VOR/DME at DFW.

(Refer to Figure 25, area 4.) The floor of Class B airspace overlying Hicks Airport (T67) north-northwest of Fort Worth Meacham Field is
The thick blue lines on the sectional chart indicate the boundaries of the overlying Class B airspace. Within each segment, the floor and ceiling are denoted by one number over a second number or the letters SFC. The floor of the Class B airspace is 4,000 feet MSL.

(Refer to Figure 26, area 4.) The CTAF/UNICOM frequency at Jamestown Airport is
CTAF (Common Traffic Advisory Frequency) is a frequency designed for the purpose of carrying out airport advisory practices and/or position reporting at an uncontrolled airport (which may also occur during hours when a tower is closed). The CTAF may be a UNICOM, MULTICOM, FSS, or tower frequency and is identified in the appropriate aeronautical publications. A solid dot with the letter 'C' inside indicates Common Traffic Advisory Frequency; it may be a UNICOM, MULTICOM, FSS, or tower frequency.

(Refer to Figure 14.) The wind and temperature at 12,000 feet MSL as reported by a pilot are
080° at 21 knots and -7°C.

Refer to Figure 18. Of what value is the Weather Depiction Chart to the pilot?
The Weather Depiction Chart is computer-prepared from METAR reports to give a broad overview of observed flying category conditions as of the valid time of the chart. From it, you can determine general weather conditions more readily than any other source. Therefore, the Weather Depiction Chart is a choice place to begin the weather briefing and flight planning.

(Refer to Figure 21.) What course should be selected on the omnibearing selector (OBS) to make a direct flight from Mercer County Regional Airport (area 3) to the Minot VORTAC (area 1) with a TO indication?
Use the following steps: 1. Plot a direct course from Mercer Airport to the Minot Airport VORTAC. 2. Note the radial (magnetic course FROM Minot VORTAC) on which the plotted course lies (179°). 3. Determine the course TO Minot VORTAC by finding the reciprocal: TO = FROM + 180° TO = 179° + 180° TO = 359°

(Refer to Figure 27.) An aircraft departs an airport in the eastern daylight time zone at 0945 EDT for a 2-hour flight to an airport located in the central daylight time zone. The landing should be at what coordinated universal time?
Use the following steps: 1. Convert the EDT takeoff time to UTC: 0945 EDT takeoff time + 0400 conversion = 1345Z UTC (also called 'ZULU' time) 2. Add the flight time to the ZULU time of takeoff: 1345Z takeoff time + 0200 = 1545Z time of landing

An ATC radar facility issues the following advisory to a pilot flying on a heading of 360°: 'TRAFFIC 10 O'CLOCK, 2 MILES, SOUTHBOUND...' Where should the pilot look for this traffic
If an aircraft is proceeding on a heading of 360° (north), traffic located at the 10 o'clock position would be 60° (left) of the nose, or to the northwest.

Refer to Figure 15. The only cloud type forecast in TAF reports is
Cumulonimbus clouds are the only cloud types forecast in TAFs.

(Refer to Figure 19.) Interpret the weather symbol depicted in Utah on the 12-hour Significant Weather Prognostic Chart.
What is Moderate turbulence, surface to 18,000 feet symbol depicted on the 12 hour Significant Weather Prog Chart in Utah ?

(Refer to Figure 21.) Determine the magnetic heading for a flight from Mercer County Regional Airport (area 3) to Minot International (area 1). The wind is from 330° at 25 knots, the true airspeed is 100 knots, and the magnetic variation is 10° east.
Use the following steps: 1. Plot the course from Mercer County Regional Airport to Minot Airport. 2. Measure the true course angle at the approximate midpoint of the route. The true course (TC) is 011°. 3. Find the true heading using a flight computer: Wind direction is 330° (given in question) Wind speed is 25 knots (given in question) True course is 011° (found in Step 2) True airspeed is 100 knots (given in question) Therefore, the true heading is 002°. 4. Calculate the magnetic heading by subtracting the easterly variation (10°) from the true heading (002°). MH = TH ± VAR MH = 002° - 10°E MH = 352°

Under what condition may an aircraft operate from a satellite airport within Class C airspace?
For aircraft departing a satellite airport, two-way radio communication must be established as soon as practicable and thereafter maintained with ATC while within the area.
400
(Refer to Figure 12.) Which of the reporting stations have VFR weather?
KINK, KBOI, and KLAX.
400
(Refer to figure 19.) At what altitude is the freezing level over the middle of Florida on the 12-hour Significant Weather Prognostic Chart?
The dashed line indicates the freezing level above mean sea level. The '120' indicates the freezing level to be at 12,000 feet over the middle of Florida.
400
(Refer to Figure 25, area 5.) The VOR is tuned to the VOR-DME at the Dallas-Fort Worth airport. The omnibearing selector (OBS) is set on 253°, with a TO indication, and a right course deviation indicator (CDI) deflection. What is the aircraft's position from the VOR-DME?
The course selected is 253° and the TO/FROM indicator has a TO flag, which means the aircraft is south of the course but north of the VOR. The CDI needle is deflected to the right, which means the aircraft is left (or east) of the course. Therefore, the aircraft must be to the east northeast of the station to satisfy the VOR indications.
400
(Refer to Figure 21, area 3.) Which airport is located at approximately 47°21'N latitude and 101°01'W longitude?
Graticules on Sectional Aeronautical Charts are the lines dividing each 30 minutes of latitude and each 30 minutes of longitude. Each tick mark represents one minute of latitude or longitude. Latitude increases northward, west longitude increases going westward. Washburn is located at approximately 47°21'N latitude and 101°01'W longitude.

A non-tower satellite airport, within the same Class D airspace as that designated for the primary airport, requires radio communications be established and maintained with the
Radio communications must be established and maintained with the primary control tower even when operating to and from a non-tower airport located within the lateral limits of Class D airspace. On takeoff from a satellite airport, communication must be established as soon as practicable after takeoff.

When the term 'light and variable' is used in reference to a Winds Aloft Forecast, the coded group and windspeed is
When the forecast speed is less than 5 knots, the coded group is '9900' and reads 'light and variable' on the Winds Aloft Forecast

(Refer to Figure 19.) What weather is forecast for the Florida area just ahead of the stationary front during the first 12 hours?
The two left panels are 12-hour progs. The upper left panel is the 12-hour prog of significant weather from the surface (SFC) to 400 millibars (24,000 feet). The Florida area is outlined in a scalloped line, indicating MVFR conditions of ceiling 1,000-3,000 feet inclusive and/or visibility 3-5 miles inclusive. The bottom left panel is the 12-hour surface prog. The shaded area with 3 circles indicates continuous rain.

If receiver autonomous integrity monitoring (RAIM) capability is lost in flight,
The GPS receiver verifies the integrity (usability) of the signals received from the GPS constellation through receiver autonomous integrity monitoring (RAIM) to determine if a satellite is providing corrupted information. At least one satellite, in addition to those required for navigation, must be in view for the receiver to perform the RAIM function; thus, RAIM needs a minimum of 5 satellites in view, or 4 satellites and a barometric altimeter (baro-aiding) to detect an integrity anomaly. For receivers capable of doing so, RAIM needs 6 satellites in view (or 5 satellites with baro-aiding) to isolate the corrupt satellite signal and remove it from the navigation solution. GPS derived altitude should not be relied upon to determine aircraft altitude since the vertical error can be quite large and no integrity is provided.
500
What is the approximate latitude and longitude of Cooperstown Airport?
Graticules on Sectional Aeronautical Charts are the lines dividing each 30 minutes of latitude and each 30 minutes of longitude. Each tick mark represents one minute of latitude or longitude. Latitude increases northward, west longitude increases going westward. Cooperstown airport is approximately at 47°25'N latitude, and 98°06'W longitude.
