ATPL VIVA QUESTIONS 65236335 1. What is the required instrumentation for RVSM? 2. If a pilot is unable to maintain RVSM, what is the RT phraseology? 3. What is ETOPS, Different extensions available 4. What is TCAS? 5. How does TCAS work? Difference between TCAS I and II 6. What is the difference between GPWS and EGPWS 7. Questions on runway lighting (from jeppesons) 8. Questions on runway marking (Jeppesons) 9. Radio failure procedure in Radar, Non-Radar and during a SID 10. Requirements for ILS Cat IIIb 11. DH and RVR requirement for cat IIIb 12. Is middle marker mandatory for ILS approaches 13. Outer marker – colour of visual lighting, frequency, morse code and distance 14. Wind shear mode in GPWS. What is predictive wind shear(a 320 kingfisher pilot got grilled on this topic) 15. If you are navigating using triple INS and if all three fail, how will you navigate (The same 320 pilot answered raw data but the examiner was looking for gps as an answer) 16. What is CANPA? How is it useful? 17. Why is 50 feet added to MDA to calculate DDH in a CANPA approach? 18. Why is 50 feet not added to the DH in an ILS approach if the same if done for a CANPA approach to calculate the DDH? 19. What is FANS? 20. What is RNP? Required equipment for RNP-5 21. Why is the instrumentation for RNP-10 more complex than RNP-5? 22. ETOPS: What is the difference between adequate airport and suitable airport? 23. Questions on approach plate symbols Height of highest obstacle, MSA, Circling minima etc 24. What is the code for NDB in an approach plate (6…3 for vor and 1 for ils) 25. Questions on enroute chart symbols fir boundary, navigation and communication frequency change over point, MEA 26. What is MORA? How is MORA calculated? 27. What is mountainous area? (Jeppeson definition) 28. Questions on lighting in TVASI, Pulsating VASI 29. How do you carry out a CANPA approach if FAF is not published? How is the FAF crossing height calculated? 30. How is the height of cloud base calculated using weather radar? 31. Frequency of operation, working of weather radar? 32. In NDB chart for Runway 07 chennai, visibility minima for cat c and cat d aircraft is published as 3400 and 5000 m respectively. If prevailing visibility is 3400 m, can the approach be carried out for a cat b category aircraft? 33. VOR interception angles while going outbound and inbound to a station 34. Working of GPS 35. Questions on WAAS and LAAS 36. Questions on type of FMS aboard the aircraft you fly 37. How do you navigate to the north pole(the answer examiners are looking for is grid navigation) 38. What is DVOR? 39. What is the modulation pattern of a reference and variable signal in DVOR 40. In Chennai, what is the direction of the runway slope? (the whole idea is supposedly to check if you are familiar with the aerodrome you operate out of) 41. Why is circle to land operations not allowed south of RWY 27 in Mumbai? These were the questions which I got and those I managed to gather from the people who did their ATPL oral. Hope it helps!
