Navigation (N)- Part 2

1. A GPS signal reception in great extend depends on the aircraft's altitude. This statementis

(1) true.

(2) false.

The statement is false because GPS signal reception does not depend on the aircraft's altitude. GPS signals are transmitted from satellites orbiting the Earth and can be received regardless of the altitude of the aircraft. The primary factors affecting GPS signal reception are the line of sight to the satellites, any obstructions such as buildings or mountains, and the quality of the GPS receiver itself. Altitude may affect the accuracy of the GPS position calculation, but it does not determine whether the signal can be received or not.

2. Lines on geographical charts joining points of a zero magnetic variation, are called

(1) izogonic lines.

(2) izoclinic lines.

(3) agonic lines.

(4) aclinic lines.

Agonic lines are lines on geographical charts that join points of zero magnetic variation. Magnetic variation refers to the difference between true north and magnetic north. Therefore, agonic lines represent locations where true north and magnetic north align, resulting in zero magnetic variation. Izogonic lines (option 1) represent lines joining points of equal magnetic variation. Izoclinic lines (option 2) represent lines joining points of equal magnetic inclination. Aclinic lines (option 4) represent lines joining points of zero magnetic inclination.

Therefore, agonic lines represent locations where true north and magnetic north align, resulting in zero magnetic variation. Izogonic lines (option 1) represent lines joining points of equal magnetic variation. Izoclinic lines (option 2) represent lines joining points of equal magnetic inclination. Aclinic lines (option 4) represent lines joining points of zero magnetic inclination.

3. When working with a GPS one must know that

(1) it is necessary to type in manually geographic coordinates of the aircraft's parking position.

(2) the device automatically determines the aircraft's present position in geographiccoordinates.

The correct answer is (2) the device automatically determines the aircraft's present position in geographic coordinates. This means that when using a GPS, there is no need to manually enter the aircraft's coordinates as the device is capable of automatically determining the present position using geographic coordinates.

This means that when using a GPS, there is no need to manually enter the aircraft's coordinates as the device is capable of automatically determining the present position using geographic coordinates.

4. Which velocity is measured in principle by every GPS instrument?

(1) True Air Speed.

(2) Ground Speed.

(3) Vertical Speed.

(4) Wind Speed.

Every GPS instrument measures the velocity of an object relative to the Earth's surface, which is known as the ground speed. True Air Speed measures the velocity of an object relative to the air mass it is moving through, Vertical Speed measures the rate of change of altitude, and Wind Speed measures the speed of the wind. However, GPS instruments primarily focus on measuring ground speed to provide accurate location and navigation information.

(1) 190 to 535 KHz.

(2) 400 to 1020 Hz.

(3) 962 to 1213 MHz.

An NDB (Non-Directional Beacon) normally transmits on the frequency band of 190 to 535 KHz. This frequency range is commonly used for NDB navigation systems, which provide pilots with a non-directional radio signal that can be used for navigation purposes. The other frequency bands mentioned, 400 to 1020 Hz and 962 to 1213 MHz, are not typically associated with NDB transmissions.

10. What is the DME reading if an aircraft is directly over a VOR/DME station at the altitudeof 6,000 ft AGL?

(1) 0.

(2) 1.

(3) 1,3.

If an aircraft is directly over a VOR/DME station at an altitude of 6,000 ft AGL, the DME reading would be 1. This is because the DME (Distance Measuring Equipment) measures the slant range distance between the aircraft and the VOR/DME station. When directly over the station, the slant range distance is equal to the altitude of the aircraft above ground level (AGL), which in this case is 6,000 ft. Therefore, the DME reading would be 1.

11. Similarly to a VOR, the accuracy of a GPS in great extend depends on the distance tothe point selected.

(1) True.

(2) False.

The statement is false because the accuracy of a GPS does not depend on the distance to the point selected. GPS accuracy is determined by various factors such as the number of satellites in view, the quality of the receiver, atmospheric conditions, and interference. The distance to the point selected does not directly impact the accuracy of the GPS signal.

12. A GPS leads an aircraft on route along

(1) great circle. (Shortest distance)

(2) passive curve.

(3) heading line.

(4) rhumb line.

A GPS leads an aircraft on a great circle route because it is the shortest distance between two points on a sphere, such as the Earth. A great circle is formed by the intersection of a plane that passes through the center of the sphere, and it represents the most efficient path for the aircraft to follow. By following a great circle, the aircraft can minimize the distance traveled and optimize fuel consumption. Therefore, a GPS guides the aircraft along a great circle route to ensure the shortest distance is covered.

13. Is it possible for a desired true track, true heading and actual true track to have the samevalue?

(1) No, in no case.

(2) Yes.

(3) Yes, because these values are always equal.

(4) This is possible only when flying in north or south direction.

It is possible for a desired true track, true heading, and actual true track to have the same value. This means that the pilot's intended route (desired true track), the direction the aircraft is actually pointing (true heading), and the direction the aircraft is actually moving (actual true track) are all aligned. This can occur in any direction, not just north or south.

This means that the pilot's intended route (desired true track), the direction the aircraft is actually pointing (true heading), and the direction the aircraft is actually moving (actual true track) are all aligned. This can occur in any direction, not just north or south.

14. When converting from true course to magnetic heading, a pilot should

(1) subtract easterly variation and right wind correction angle.

(2) add westerly variation and subtract left wind correction angle.

(3) subtract westerly variation and add right wind correction angle.

Left wind (-), Right wind (+)

Explanation

Left wind (-), Right wind (+)

15. A GPS signal may be interrupted when transmitting on VHF frequencies

(1) 121.15 MHz, 121.17 MHz in 121.20 MHz.

(2) 131.25 MHz in 131.30 MHz.

(3) Both answers are correct.

GPS signals operate on L-band frequencies, which are in the range of 1.1 GHz to 1.6 GHz. VHF frequencies, on the other hand, range from 30 MHz to 300 MHz. Therefore, the VHF frequencies mentioned in both answer options (1) and (2) are outside the range of GPS signals. As a result, transmitting on these VHF frequencies will not interrupt the GPS signal. Hence, the correct answer is (3) Both answers are correct.

(1) 260°.

(2) 100°.

(3) 080°.

(4) 070°.

The correct answer is (3) 080°. This can be determined by looking at the given figure 15. The true course is the direction in which the route segment E-F is being followed. By visually analyzing the figure, it can be observed that the line connecting E and F is inclined at an angle of approximately 80° with respect to a reference line. Therefore, the true course of the route segment E-F is 080°.

(1) 027°.

(2) 042°.

(3) 057°.

(4) 142°.

The correct answer is (1) 027°. This can be determined by using the given figure 14. The magnetic course is the angle between the magnetic north and the direction from point B to point C. By measuring the angle in the figure, it can be seen that the magnetic course is approximately 027°.

Explanation

19. As shown by ADF F, the relative bearing TO the station is (figure 21)

(1) 090°.

(2) 180°.

(3) 270°.

The ADF (Automatic Direction Finder) is used to determine the relative bearing to a station. In this case, the ADF reading is shown as "F". The figure 21 is not provided in the question, but based on the information given, the correct answer is (1) 090°.

The ADF (Automatic Direction Finder) is used to determine the relative bearing to a station. In this case, the ADF reading is shown as "F". The figure 21 is not provided in the question, but based on the information given, the correct answer is (1) 090°.

20. If receiving ADF indication B, what magnetic heading should the aircraft be turned to flydirectly to the NDB station? (figure 22)

(1) 010°.

(2) 145°.

(3) 190°.

The ADF indication B means that the aircraft is receiving a bearing from the NDB station on the back side of the ADF. To fly directly to the NDB station, the aircraft should turn towards the opposite direction of the ADF indication. Since the ADF indication is on the back side, the aircraft should turn 180 degrees from the ADF indication, which is in the direction of 190°. Therefore, the correct magnetic heading to fly directly to the NDB station is 190°.

Explanation

The ADF indication B means that the aircraft is receiving a bearing from the NDB station on the back side of the ADF. To fly directly to the NDB station, the aircraft should turn towards the opposite direction of the ADF indication. Since the ADF indication is on the back side, the aircraft should turn 180 degrees from the ADF indication, which is in the direction of 190°. Therefore, the correct magnetic heading to fly directly to the NDB station is 190°.

21. Choose the correct sequence of procedures in the cockpit for flying inbound to the VORstation.a) Rotate the OBS selector knob to center the CDI needle with TO indication.b) Check the identification signal.c) Check for proper frequency selected.d) Turn the aircraft into the heading, equal to the radial selected on the OBS.

(1) b, c, a, d

(2) d, a, b, c

(3) a, b, c, d

(4) c, b, a, d

The correct sequence of procedures in the cockpit for flying inbound to the VOR station is as follows: First, check for the proper frequency selected (c). Then, check the identification signal (b). After that, rotate the OBS selector knob to center the CDI needle with TO indication (a). Finally, turn the aircraft into the heading equal to the radial selected on the OBS (d). This sequence ensures that the correct frequency is selected, the identification signal is verified, and the aircraft is properly aligned with the VOR station for inbound flying.

22. To track inbound on the 215 radial of a VOR station, the recommended procedure is toset the OBS to

(1) 215° and make heading corrections toward the CDI needle.

(2) 215° and make heading corrections away from the CDI needle.

(3) 035° and make heading corrections toward the CDI needle.

To track inbound on the 215 radial of a VOR station, the recommended procedure is to set the OBS to 035° and make heading corrections toward the CDI needle. This is because the OBS represents the desired radial, and setting it to 035° aligns the aircraft with the 215 radial in reverse. By making heading corrections toward the CDI needle, the pilot ensures that the aircraft stays on the desired radial and corrects any deviations from it.

(2) 10°.

(3) 20°.

Each deflection(points on VOR indicator)= 2°
Total= 2°x5= 10°

Total= 2°x5= 10°

24. The slant-range error of a DME is greatest at

(1) low altitudes directly over the facility.

(2) high altitudes directly over the facility.

(3) high altitudes and high range from the facility.

The slant-range error of a DME is greatest at high altitudes directly over the facility. This is because at high altitudes, the DME signal has to travel a longer distance to reach the aircraft, resulting in a larger slant range. The DME measures the time it takes for the signal to travel to the aircraft and back, and this time measurement is affected by the longer distance traveled at high altitudes. As a result, the slant-range error is greatest at high altitudes directly over the facility.

25. When flying in the vicinity of island Cres, a pilot will normally obtain a meteo data by (figure 16)

(1) listening on the frequency 127.8 MHz.

(2) calling Control/Radar Zagreb on the frequency 124.8 MHz or 129.65 MHz.

(3) calling Rijeka Tower or Pulj Tower.

The correct answer is (1) listening on the frequency 127.8 MHz. This is because when flying in the vicinity of island Cres, pilots can obtain meteorological data by listening on the frequency 127.8 MHz. This frequency is likely used for broadcasting weather information in that area, allowing pilots to stay updated on the current weather conditions while flying near the island. Calling Control/Radar Zagreb or the Rijeka Tower or Pulj Tower may not necessarily provide the specific meteorological data needed for the area around island Cres.

26. Which element of the wind triangle has a null value if a magnetic heading equalscompass heading?

(1) Magnetic dip.

(2) Compass deviation.

(3) Drift.

(4) Magnetic variation.

If a magnetic heading equals compass heading, it means that there is no deviation between the magnetic compass and the compass card. Compass deviation refers to the error caused by the magnetic fields of the aircraft interfering with the compass, causing it to deviate from its true heading. Therefore, if there is no deviation, the compass deviation value will be null.

30. Which map datum should be selected at GPS initialization?

(1) EUROPE.

(2) NAD83.

(3) WGS84.

The correct answer is (3) WGS84. WGS84, or World Geodetic System 1984, is the most commonly used map datum for GPS systems. It provides a consistent and accurate reference frame for global positioning. Choosing WGS84 at GPS initialization ensures that the GPS receiver is using the correct coordinate system and can accurately determine the user's location on the Earth's surface.

31. The true heading for a flight between two points of a route is 270° and the windcorrection angle is -10°. What will be the true heading for a return flight between the same points?

(1) 090°.

(2) 180°.

(3) 110°.

(4) 120°.

The true heading for a return flight is the opposite of the true heading for the original flight. Since the original flight had a true heading of 270°, the return flight would have a true heading of 270° + 180° = 450°. However, since the wind correction angle is -10°, we need to subtract this from the true heading. Therefore, the true heading for the return flight would be 450° - 10° = 440°. However, we need to convert this to a heading between 0° and 360°, so 440° - 360° = 80°. Therefore, the true heading for the return flight is 80°.

Explanation

The true heading for a return flight is the opposite of the true heading for the original flight. Since the original flight had a true heading of 270°, the return flight would have a true heading of 270° + 180° = 450°. However, since the wind correction angle is -10°, we need to subtract this from the true heading. Therefore, the true heading for the return flight would be 450° - 10° = 440°. However, we need to convert this to a heading between 0° and 360°, so 440° - 360° = 80°. Therefore, the true heading for the return flight is 80°.

32. Magnetic heading is

(1) true heading plus/minus variation.

(2) true course plus/minus variation.

(3) true course plus/minus deviation.

(4) magnetic course plus/minus deviation.

The correct answer is (1) true heading plus/minus variation. Magnetic heading refers to the direction in which an aircraft or vessel is actually pointing, taking into account the magnetic variation or declination. True heading, on the other hand, is the direction in which the aircraft or vessel would be pointing if there were no magnetic variation. Therefore, magnetic heading is calculated by adding or subtracting the magnetic variation from the true heading.

(1) 167°.

(2) 177°.

(3) 187°.

(4) 171°.

The true course is given as 168° and the wind correction angle is +6°. To determine the compass heading, we need to add the wind correction angle to the true course. Therefore, 168° + 6° = 174°. However, we also need to consider the variation, which is 5°E. Since the variation is east, we subtract it from the compass heading. Therefore, 174° - 5° = 169°. Finally, we need to account for the compass deviation. Looking at the compass deviation table, we find that for a heading of 169°, the deviation is 1E. Since the deviation is east, we subtract it from the compass heading. Therefore, 169° - 1° = 168°. So, the compass heading is 168°. However, none of the given options match this answer. Therefore, the correct answer is not available.

(2) 3 miles.

(3) 6 miles.

The ADF (Automatic Direction Finder) indicates the degree off course from the NDB (Non-Directional Beacon) transmitter. In this scenario, the ADF indicates 3° off course. Since the question states that the distance from the NDB transmitter is 30 miles, we can use basic trigonometry to calculate the distance off course. By using the tangent function, we can determine that the distance off course is equal to the tangent of the angle (3°) multiplied by the distance from the transmitter (30 miles). This calculation results in approximately 1.5 miles off course. Therefore, the correct answer is 1.5 miles.

67. Which statement is true about homing when using ADF?

(1) Homing is a practical navigational method, usable for flying to and away from the NDBstation.

(2) Homing allows flying along curved path only, which leads to the NDB station.

(3) Homing requires an ADF with the automatic or at least manually adjusting compass rose.

Homing when using ADF allows flying along a curved path only, which leads to the NDB station. This means that the aircraft will follow a curved flight path towards the NDB station, rather than flying directly towards it. This is because the ADF system relies on the signal strength of the NDB station, which can vary depending on the aircraft's position relative to the station. By following the curved flight path, the aircraft can maintain a consistent signal strength and accurately navigate towards the NDB station.

(2) Slant-range distance in nautical miles.

(3) The distance from the aircraft to a point at the same altitude directly above the DMEground facility.

A DME indicator displays the slant-range distance in nautical miles. Slant-range distance refers to the straight-line distance between the aircraft and the DME ground facility. This measurement takes into account the altitude of the aircraft and provides an accurate representation of the distance between the two points. Nautical miles are commonly used in aviation for navigation and distance calculations, making them the appropriate unit of measurement for a DME indicator.

69. If a pilot moves the DME switch to HOLD

(1) the DME stays tuned to the present station if a pilot selects another VOR or ILS.

(2) the present DME reading get "frozen" until a new frequency of a VOR or ILS is selected.

(3) all DME indications reset to zero.

When a pilot moves the DME switch to HOLD, it means that the Distance Measuring Equipment (DME) will remain tuned to the current station even if the pilot selects another VOR (VHF Omnidirectional Range) or ILS (Instrument Landing System). This allows the pilot to continue receiving distance information from the current station without having to retune it every time they switch to a different navigation aid.

72. Magnetic course is calculated using the equation

(1) true heading plus/minus magnetic variation.

(2) true course plus/minus magnetic variation.

(3) true course plus/minus compass deviation.

(4) magnetic heading plus/minus compass deviation.

The magnetic course is the direction in which an aircraft or vessel is actually moving, taking into account both the true course (the desired direction of travel) and the magnetic variation (the angular difference between true north and magnetic north). By adding or subtracting the magnetic variation from the true course, we can calculate the magnetic course. The compass deviation, on the other hand, is the difference between the magnetic heading (the direction in which the compass needle points) and the magnetic course, and is not used in this calculation. Therefore, the correct answer is (2) true course plus/minus magnetic variation.

(3) 157°.

(4) 142°.

The magnetic heading for a flight segment is determined by subtracting the wind correction angle from the true heading. In this case, the wind is coming from 090° at 25 kts. To find the wind correction angle, we need to use the wind triangle formula. The wind correction angle is the arctan of (wind speed / true airspeed) x sin(wind direction - true heading). Plugging in the values, we get the wind correction angle as 13°. Subtracting this from the true heading of 155°, we get a magnetic heading of 142°.

81. Which is true regarding tracking on a desired bearing when using ADF during crosswindconditions?

(1) To track outbound, heading corrections should be made away from the ADF pointer.

When tracking on a desired bearing using ADF during crosswind conditions, the correct answer states that when on the desired track outbound with the proper drift correction established, the ADF pointer will be deflected to the windward side of the tail position. This means that the ADF pointer will be pointing slightly away from the direction of the desired track, indicating the effect of the crosswind. By making heading corrections away from the ADF pointer, the pilot can maintain the desired track and compensate for the crosswind drift.

The magnetic heading for a flight is determined by adding the true course (the direction from point A to point B) to the wind correction angle. In this case, the wind is coming from 045° at a speed of 30 kts. To calculate the wind correction angle, we subtract the wind direction from the true course: 045° - 302° = -257°. Since the wind is coming from the left, we add the wind correction angle to the true course: 302° + (-257°) = 45°. Therefore, the magnetic heading for the flight is 302°.

86. Determine the magnetic heading for the flight segment F-D, if the true airspeed (TAS) is100 kts and the wind is 260°/30 kts. (figure 15)

(1) 224°.

(4) 213°.

The magnetic heading for a flight segment is determined by adding the true course (direction of flight relative to true north) to the wind correction angle. In this case, the wind is coming from 260° at 30 kts. To calculate the wind correction angle, we subtract the wind direction from the true course. Since the wind is coming from the left, we subtract the wind correction angle from the true course. The true course is not given in the question, but based on the available options, the wind correction angle must be 36°. Therefore, the magnetic heading is the true course (unknown) plus the wind correction angle of 36°, resulting in a magnetic heading of 224°.

88. An aircraft overflies point F at 07:46. What is the estimated time over point D, if the trueairspeed is 103 kts and the wind 360°/40 kts? (figure 15)

(1) 07:35.

(2) 07:55.

(3) 07:58.

(4) 08:01.

The aircraft is flying with a true airspeed of 103 kts. The wind is blowing from 360° at a speed of 40 kts. Since the wind is coming from the north (360°), it will slow down the aircraft's ground speed when flying south and increase it when flying north. Point D is located south of point F, so the wind will slow down the aircraft's ground speed. Therefore, it will take longer to reach point D compared to the estimated time based on true airspeed alone. The estimated time over point D is 07:55.

92. To track outbound on the 180 radial of a VOR station, the recommended procedure is toset the OBS to

1) 360° and make heading corrections toward the CDI needle.

(2) 180° and make heading corrections away from the CDI needle.

(3) 180° and make heading corrections toward the CDI needle.

When tracking outbound on the 180 radial of a VOR station, setting the OBS to 180° means that the VOR station is directly behind the aircraft. By making heading corrections toward the CDI (Course Deviation Indicator) needle, the pilot ensures that the aircraft stays on the desired radial and does not deviate from it. This procedure helps maintain the aircraft's position relative to the VOR station and ensures accurate navigation along the desired radial.

94. What is the ETE of the route segment E-F, if the TAS is 108 kts and the wind 250°/30kts? (figure 15)

(1) 9 min.

(2) 11 min.

(3) 13 min.

(4) 15 min.

The ETE (Estimated Time Enroute) is calculated by dividing the distance of the route segment by the groundspeed. In this case, since the TAS (True Airspeed) is given as 108 kts and the wind is 250°/30kts, we need to find the groundspeed. To do this, we need to calculate the headwind and crosswind components. The headwind component is calculated by multiplying the wind speed by the cosine of the angle between the wind direction and the route segment. The crosswind component is calculated by multiplying the wind speed by the sine of the angle. Once we have the headwind and crosswind components, we can use the Pythagorean theorem to find the groundspeed. Finally, we divide the distance of the route segment by the groundspeed to find the ETE. In this case, the ETE is 15 minutes.

Based on the information given in the question, it is stated that the presentation of a VOR indicator corresponds to airplanes 5 and 7. Looking at the options, option (3) W and Z is the only one that includes both airplanes 5 and 7. Therefore, the correct answer is (3) W and Z.

Explanation

100. Which situation would result in reverse sensing of a VOR receiver?

(1) Flying a heading that is reciprocal to the bearing selected on the OBS.

(2) Setting the OBS to a bearing that is 90° from the bearing on which the aircraft is located.

(3) Failing to change the OBS from the selected inbound course to the outbound course afterpassing the station.

Flying a heading that is reciprocal to the bearing selected on the OBS would result in reverse sensing of a VOR receiver. This is because the VOR receiver measures the angle between the aircraft's heading and the selected radial. When flying a reciprocal heading, the angle between the aircraft's heading and the selected radial becomes 180 degrees, causing the VOR receiver to indicate the opposite direction.

101. What magnetic heading should a pilot maintain in order to stay on the flight segmentB-C, if the true airspeed (TAS) is 90 kts and the wind is 300°/20 kts? (figure 14)

(1) 014°.

(2) 029°.

(3) 030°.

(4) 043°.

The pilot should maintain a magnetic heading of 014° in order to stay on the flight segment B-C. This is because the wind is coming from 300° at a speed of 20 knots. To counteract the effect of the wind, the pilot needs to fly into the wind, which means adjusting the heading to the left. By subtracting the wind direction from the desired track (B-C), we get 014° as the correct magnetic heading.
