*OLODE 01 Session 2025* *22nd Jan 2025* *Air Navigation* 1. A rhumb line cuts the meridian at the same angle. It represents a line of constant direction. 2. If PA is zero and deviation is -5, find DA. 3. IAS = 84, OAT = +10, PA = 8000. Calculate TAS. 4. Define QNH. 5. Explain the principle of primary radar. 6. Identify which is not an advantage of primary radar over secondary radar. 7. Calculate compass heading (values included variation, drift, deviation, and track). 8. An aircraft flies a range of 800 NM: Climbs for 30 minutes at 84 knots G/S Cruises at 180 knots G/S Descends for 30 minutes at 85 knots G/S Determine total flight time. 9. Fuel Calculation: At 120 kg/hr, find fuel required for 1 hour 20 minutes. At 8.7 gal/hr, find fuel required for 2 hours 40 minutes. 10. Given G/S and distance, calculate time (CX3 usage). 11. CP and PNR normal question—find PET. 12. TAS, track, and W/V are given. Calculate GS and THDG. 13. GS, track, HDG, and TAS are given. Calculate W/V. 14. CP PNR 2: TAS and fuel consumption given. Find PNR time. 15. 2–3 CP PNR questions where TAS and fuel consumption were given. 16. Two questions related to gyro. 17. One question to determine drift using gyro. 18. Question on critical engine failure performance. 19. Three numerical payload questions: Two easy, one moderately challenging. 20. Calculate time: Two latitudes and longitudes were provided. LMT for point A was given—find the LMT for point B. 21. What is the frequency of NDB? 22. ADF-related numericals: 4–5 questions (1 interception, others on MHdg and VOR radial). 23. Two or three figure-based questions. Choose the correct figure (e.g., RMI radial). 24. Given a figure, calculate how many degrees the aircraft must turn to align with the centerline. 25. If the aircraft is turning left, where will the needle and ball move? 26. 7–8 unique questions encountered for the first time. 27. Runway slope options: +1, 2, or 4. 28. Two questions on Rate of Descent (ROD). 29. QNH/QFE-based questions: If a pilot forgets to switch to the QNH of location B, what would the altimeter indicate? 30. Four questions on flight plans (all time-related): How to write flight time of 1 hour 55 minutes? (Options: 1h55, 115, 155) Which time is used in flight plans (UTC, LMT, etc.)? If departure is at 10:00 from A and arrival at B is 12:15, what is EET? (Options: 12:15, 02:15, 10:00) How far in advance must a flight plan be filed? 31. Two questions on map scales: One easy, one challenging. 32. On Lambert Conformal Chart: Where do we place the protractor for finding a meridian? (Options: At the start, at the end, at the destination). 33. Minimum aircraft height to receive VOR signals at 19 tAMSL and 175 NM range: Options: 26,000 ft, 16,000 ft, 24,000 ft, 20,000 ft. 34. Amplitude modulation of the ILS outer marker: Specify details. 35. The most accurate position fixing occurs when: (A) Four satellites spaced 90° apart at 30° above the horizon. (B) One satellite near the horizon and three at 60° above the horizon. (C) One satellite overhead and three at 60° above the horizon. (D) One satellite overhead and three spaced 120° near the horizon. 36. Question on ILS: 150 Hz signal stronger than 90 Hz signal. 37. What causes the varying duration of day and night throughout the year? 38. Convert 380 US gallons (specific gravity = 0.78) to kilograms. 39. Define civil twilight. *Fwd as received*
