Q11. An aircraft is flying on a heading of 270(M). The VOR OBS is also set to 270 with the full left deflection and FROM flag displayed. In which sector is the aircraft from the VOR ground station?
Explanation: OBS is set to 270° with a FROM indication, meaning the selected radial is 270°. A full left deflection means the aircraft is right of the selected radial. When flying the 270° radial, the right side of the radial lies in the NW sector relative to the station. Therefore the aircraft is located in the NW sector.
Q12. A/C is on radial 240, HDG 230. CDI showing three dots fly right indication. To/From showing TO. Find: (i) OBS (ii) Type of sensing
Explanation: Aircraft is on radial 240. CDI shows two dots fly right, meaning the selected course is 4 right of the aircraft position ? 240 ? 4 = 236. The inbound course (OBS) is the reciprocal: 236 ? 180 = 056. Aircraft heading 230 is opposite to the selected course, therefore sensing is Reverse.
Q13. Aircraft heading is 080 deg (M). OBS is selected to 060 deg. Aircraft is on a radial of 040 deg (M). To/from indication and CDI will show:
Explanation: Aircraft is on radial 040 ( i.e Outbound = 040, Homebound 220 ), Given OBS is set to 060, so the aircraft is trying to track a course away from the station. The aircraft position (040) is 20 left of the selected course (060), therefore the CDI indicates fly Right 20 Degree and the flag shows FROM.
Q14. An aircraft has tuned a VOR station. When 049 is selected on the OBS, the CDI is centered and the TO indication is displayed. Determine the aircraft radial and the magnetic heading required to reach the station.
Explanation: When OBS is set to 049 and the CDI is centered with a TO indication, the aircraft is on the 049 inbound course to the station. VOR radials are always defined FROM the station, therefore the aircraft must be on the reciprocal radial: 049 + 180 = 229 radial. To fly to the station along the selected course, the aircraft heading required is 049 (Magnetic). Hence the aircraft is on 229 radial and must fly heading 049 (M) in NILL wind Conditions.
Q15. An a/c hdg is 041 (M). At 17.5 nm from a VOR. A/C is on magnetic bearing of 215 from VOR. OBS selection 212. VOR and NDB are co-located. Find the RB and RMI indications.
Explanation: Aircraft is on magnetic bearing 215 from the VOR (215 radial), so the bearing to the station is the reciprocal 035; RMI therefore indicates 035, and with aircraft heading 041, RB = 035 ? 041 = ?6 = 354, hence RB 354, RMI 035.
Q16. An a/c hdg is 041 (M). At 17.5 nm from a VOR. A/C is on magnetic bearing of 215 from VOR. OBS selection 212. VOR and NDB are co-located. Determine the To/From indication.
Explanation: Aircraft is on magnetic bearing 215 from the VOR (radial 215). OBS is set to 212, which is close to the aircraft radial (FROM direction), therefore the CDI will display a FROM indication.
Q17. An a/c hdg is 041 (M). At 17.5 nm from a VOR. A/C is on magnetic bearing of 215 from VOR. OBS selection 212. VOR and NDB are co-located. Determine the CDI indication.
Explanation: Aircraft is on radial 215 and OBS is set to 212. The aircraft is therefore 3 right of the selected course. CDI commands correction toward the course, so the indication will be fly left. Since the difference is 3 degrees, the deviation is about 1.5 dots left.
