13.  118.0 – 135. 95 MHz is used for VHF voice communication.

14.   “Omit position reports” means: Do not give position reports. This will usually happen when the controller can track you on the radar.

15.  ATIS gives the pilot – Info regarding an airport including MET info.

16.  30,000 KHz is – 30 MHz.

17.  According to ICAO position report in CVFR include – the time & level/alt over compulsory reporting point.

18.  A transmission with wave length of 5 cm belongs to SHF band. This is because the frequency of such a wave is: 300,000,000/0.05=6,000,000,000=6GHz.

19.  The critical angle for HF waves is defined as: the angle beyond which the sky wave is not reflected.

20.  Acknowledge means: let me know that you have received & understood this message.

21.  Transponder code 7500 is for – Unlawful interference in flight.

22.  Disadvantages of a carbon microphone are: its low fidelity and the need for external power source to activate it.

23.  FIR is – Flight Information Region.

24.  Line of sight wave = direct wave.

25.  YK=Syria

26.  Base of cloud = QBB

27.  Emergency frequencies are: 121.5 MHz 243 MHz 500 kHz 2182 kHz.

28.  To impose silence is to-Stop communication after a distress call has been made.

29.  Negative means – No; Permission not granted; that is not correct.

30.  A ground station making a test signal – shell be composed of spoken Numbers.

31.  Info regarding severe turbulence will be reported by ATC as – SIGMET.

32.  CAVOK means Ceiling And Visibility OK– Visibility above 10 Km. no clouds below 5000’.

39.  The leg before final is called – Base leg.

40.  VOLMET is – Broadcast of actual weather & forecast transmitted on VHF & in certain places on HF at specified time.

41.  Test signals of radio equipment shell not continue more then – 10 sec.

42.  A class A bearing given to a/c by a DF station is – Accurate within ± 2 degrees.

43.  Disregard means – Consider that transmission as not being sent.

44.  The sound wave changes the electric resistance of the microphone – Carbon Microphone.

45.  Urgent – PAN PAN

46.  Network – a number of ground stations working on the same frequencies & handling traffic between them.

47.  Aircraft flying at 10,000 feet with VHF transmitter – 123 NM max range.

48.  4X-AJV called by unidentified aeronautical station shall say “ station calling 4X-AJV say your call sign again”.
