Options: A. 239°(T) B. 223°(T) C. 233°(T) D. 213°(T) Answer: A Explanation: The true bearing from the NDB to the aircraft is calculated by subtracting the Deviation (+3°) and Variation (13°E) from the Compass Heading (241°). Therefore, 241° - 3° - 13° = 225°. Since the RBI needle head is at 162°, the relative bearing is 162° which means the aircraft is 162° to the right of the true bearing. To find the true bearing, we subtract the relative bearing from the calculated bearing, so 225° - 162° = 63°. However, since the RBI shows the bearing from the aircraft to the NDB, we take the reciprocal of 63° which is 243°. Hence, the true bearing from the NDB to the aircraft is 243°(T). Question 2 License License ATPL (H) Radio Navigation Practice Exam PDF https://www.easy-quizzz.com/gb/ Refer to figure. When intercepting the glide path from below and from the left, which PFD shows the correct indications to begin descending on the glide path? Options: A. Figure D B. Figure C C. Figure B D. Figure A Answer: A Explanation: Question 3 What is the minimum number of satellites required for signal reception in order to carry out an independent three-dimensional fix, Receiver Autonomous Integrity Monitoring (RAIM) and failure detection and exclusion of any faulty satellite? Options: A. 4 B. 5 C. 6 D. 7 Answer: C Explanation: For signal reception to carry out an independent three-dimensional fix, Receiver Autonomous Integrity Monitoring (RAIM), and failure detection and exclusion of any faulty satellite, a minimum of 6 satellites are required. Question 4 Concerning PBN - Performance Based Navigation - what is the name of a curved terminal or approach section, defined by fix, radius & arc length? Options: A. Radius approach B. Fixed arc approach License License ATPL (H) Radio Navigation Practice Exam PDF https://www.easy-quizzz.com/gb/ C. Fixed radius path D. Curved terminal approach Answer: C Explanation: The curved terminal or approach section, defined by fix, radius & arc length in PBN is called a Fixed radius path. Question 5 Which of the following equipment uses primary radar principles (PSR)? Options: A. Airborne weather radar (AWR). B. Distance Measuring Equipment (DME). C. Global Positioning System (GPS). D. Secondary Surveillance Radar (SSR). Answer: A Explanation: Primary Surveillance Radar (PSR) equipment uses primary radar principles, not Airborne Weather Radar (AWR). Primary radar systems emit radio waves which are reflected by aircraft and detected by the radar unit to determine the position and distance of the aircraft. Question 6 A radio signal may be classified by three symbols according to the International Telecommunication Union (ITU) code. The abbreviation A3E is used for the type of transmission in which the carrier wave is.... Options: A. amplitude modulated by a speech signal, such as is used for VHF-COM B. a continuous wave interrupted with a keyed Morse code ident as used by an NDB C. amplitude modulated to transmit the Morse code ident, as is used by a VOR D. interrupted to transmit the Morse code identification, as used by an NDB Answer: A Explanation: The abbreviation A3E is used for the type of transmission in which the carrier wave is amplitude modulated by a speech signal, such as is used for VHF-COM.

B. tells whether a track equal to the selected bearing will bring you to or away from the VOR. C. tells whether the deviation indicator shows that you should manoeuvre the aircraft towards or from the CDI needle. D. tells whether you should turn the aircraft towards or away from the CDI indication. Answer: B Explanation: The TO/FROM indicator of a VOR tells whether a track equal to the selected bearing will bring you to or away from the VOR. Question 8 User Equivalent Range Error (UERE) or User Range Error (URE) is a signal-in-space error consisting of several individual errors. One of these individual errors is variations to the satellite orbit, or ephemeris, which is caused by... Options: A. solar winds and gravitational forces of the Sun and the Moon. B. jet streams and areas of significant weather along the orbit. C. high solar activity causing variations to the depth of the ionosphere. D. stronger than forecast ionospheric winds and electromagnetic forces. Answer: A Explanation: User Equivalent Range Error (UERE) or User Range Error (URE) is a signal-in-space error consisting of several individual errors. One of these individual errors is variations to the satellite orbit, or ephemeris, which is caused by solar winds and gravitational forces of the Sun and the Moon. Question 9 What ground/air based systems must be used to comply with RNP/RNAV 10 requirements ? Options: License License ATPL (H) Radio Navigation Practice Exam PDF https://www.easy-quizzz.com/gb/ A. None of the above. B. DME/DME C. VOR/DME D. DME/DME/IRU Answer: A Explanation: To comply with RNP/RNAV 10 requirements, no ground/air based systems must be used. Question 10 The operating mode of a transponder depends on the... Options: A. length of the interrogation pulses. B. time interval between the interrogation pulse pairs. C. frequency of the carrier wave. D. repetition frequency of interrogation pulse pairs. Answer: B Explanation: The operating mode of a transponder depends on the time interval between the interrogation pulse pairs. Would you like to see more?
