How many satellites make up the Global Positioning System (GPS)?
9.
(Refer to Figure 20, area 3; and Figure 28.) The VOR is tuned to Elizabeth City VOR, and the aircraft is positioned over Shawboro. Which VOR indication is correct?
18 nautical miles from Norfolk VORTAC.
(Refer to Figure 20.) What is your approximate position on low altitude airway Victor 1, southwest of Norfolk (area 1), if the VOR receiver indicates you are on the 340° radial of Elizabeth City VOR (area 3)?
359°.
(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?
196°.
(Refer to Figure 23.) On what course should the VOR receiver (OBS) be set to navigate direct from Hampton Varnville Airport (area 1) to Savannah VORTAC (area 3)?
Briggs private airfield.
(Refer to Figure 23.) What is the approximate position of the aircraft if the VOR receivers indicate the 320° radial of Savannah VORTAC (area 3) and the 191° radial of Allendale VOR (area 1)?
100°.
(Refer to Figure 24.) On what course should the VOR receiver (OBS) be set in order to navigate direct from Majors Airport (area 1) to Quitman VORTAC (area 2)?
Glenmar Airport.
(Refer to Figure 24.) What is the approximate position of the aircraft if the VOR receivers indicate the 245° radial of Sulphur Springs VOR-DME (area 5) and the 145° radial of Bonham VORTAC (area 3)?
East-northeast.
(Refer to Figure 25, area 5.) The VOR is tuned to the Maverick VOR/DME. 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 VORTAC?
East-Northeast.
(Refer to Figure 25, area 5.) The VOR is tuned to the Ranger VORTAC. The omnibearing selector (OBS) is set on 256°, with a TO indication, and a left course deviation indicator (CDI) deflection. What is the aircraft's position from the VORTAC?
VOR/DME.
(Refer to Figure 25, area 5.) The navigation facility at Dallas-Ft. Worth International (DFW) is a
North.
(Refer to Figure 28, illustration 4.) The VOR receiver has the indications shown. What is the aircraft's position relative to the station?
030°.
(Refer to Figure 28, illustration 5.) The VOR receiver has the indications shown. What radial is the aircraft crossing?
Southeast.
(Refer to Figure 28, illustration 7.) The VOR receiver has the indications shown. What is the aircraft's position relative to the station?
A single dot inside a hexagon with tabs on three of the sides.
(Refer to Legend 1) A VORTAC station is represented by
A runway configuration with a dot.
(Refer to Legend 1) What symbol would indicate a VORTAC location on an airport?s
A hexagon with a dot in the center and enclosed within a square.
(Refer to Legend 1) Which of the symbols depicted with a hexagon represents a VOR-DME?
under VFR flight for situational awareness.
A GPS with an expired database may be used
No, there can be too many errors in the vertical height computations of the GPS to rely on it as an altimeter.
Can a GPS be used as an altimeter?
4.
How many Global Positioning System (GPS) satellites are required to yield a three dimensional position (latitude, longitude, and altitude) and time solution?
the pilot has no assurance of the accuracy of the GPS position.
If Receiver Autonomous Integrity Monitoring (RAIM) capability is lost in-flight,
5.
What is the minimum number of Global Positioning System (GPS) satellites that are observable by a user anywhere on earth?
0° FROM or 180° TO, regardless of the pilot's position from the VOT.
When the course deviation indicator (CDI) needle is centered using a VOR test signal (VOT), the omnibearing selector (OBS) and the TO/FROM indicator should read
