Q1. What does the Relative Bearing Indicator (RBI) display?
RBI indicates relative bearing measured clockwise from aircraft nose. Ref: ADF Instrument description
Q2. Relative Bearing (RB) is measured from:
Relative bearing is measured clockwise from aircraft nose (0°–360°). Ref: Navigation instruments
Q3. The formula to calculate Magnetic Bearing (MB) using RBI is:
MB = Magnetic Heading + Relative Bearing (adjust 360 for MB>360).
Q4. An aircraft Magnetic heading is 090° and the RBI indicates 045°. What is the magnetic bearing to the station?
135° (MB = MH + RB → 090 + 045 = 135). Ref: Standard ADF/RBI bearing formula
Q5. Which instrument combines heading information and bearing to station on one display?
RMI (Radio Magnetic Indicator) automatically shows magnetic bearing to the station on the tip of the needle. and magnetic heading on the TOP.
Q6. Aircraft heading 335°T and Var 5 E, RBI reads 120°. Determine the magnetic bearing to the station.
090° (330+ 120 = 450 → 450 − 360 = 090). Ref: ADF Bearing calculation
Q7. Aircraft Magnetic heading 210°, RBI shows 300°. What is the magnetic bearing to the station if variatin of aircraft is +5?
150° (210 + 300 = 510 → 510 − 360 = 150)
Q8. Refer to the image. What is the Magnetic Bearing (QDM) to the station?
270°. Calculation: MB (QDM) = MH + RB = 180° + 090° = 270°. Ref: ADF Bearing Formula
Q9. Aircraft Magnetic heading 045° and RBI pointer shows 315°. Determine the magnetic bearing to the station.
000° (045 315 = 360 → 000°). Ref: MB = MH RB
Q10. The North aligned RBI pointer indicates 090°. Where is the station located relative to the aircraft?
Right of aircraft. Relative bearing is measured clockwise from the aircraft nose. Ref: Relative Bearing definition
Q11. Refer to the image. What is the Magnetic Bearing FROM the station (QDR)?
090°. QDR = QDM ± 180°. Ref: ADF Navigation terminology
Q12. Refer to the image. Given : Variation = 5E. What is the True Bearing (QUJ) to the station?
275°.
Q13. Refer to the image. What is the Magnetic Bearing (QDM) to the station?
Q14. The Fixed card RBI shows approximately 330° relative bearing. Where is the station located relative to the aircraft?
Ahead and slightly left. 330° relative bearing means 30° left of the aircraft nose. Ref: Relative Bearing concept
Q15. Refer to the image.What is the Magnetic Bearing (QDM) to the station?
090°. Calculation: MB = MH RB → 090° 000° = 090°. Ref: ADF Bearing Formula
Q16. Refer to the image Where is the station located relative to the aircraft?
Directly ahead of the aircraft. Relative bearing 000° means the station is straight ahead. Ref: Relative Bearing definition
Q17. Refer to the image. What is the Magnetic Bearing FROM the station (QDR)?
270°. QDR = QDM ± 180°
Q18. Refer to the image. What is the Magnetic Bearing (QDM) to the station?
Q19. Refer to the image. Where is the station located relative to the aircraft?
Ahead and slightly left. 315° relative bearing means 45° to the left of the aircraft nose. Ref: Relative Bearing concept
Q20. Refer to the image. Given : Variation = 5W. What is the True Bearing (QUJ) to the station?
