5.
The VOR in an aircraft is correctly tuned and set to define the centre line of an airway within UK airspace which you intend to fly. The indication received on the VOR/ILS deviation indicator is shown in the diagram alongside. At the same time the DME gave a range of 40 nm from the facility. Use the above information to answer the next two questions. Use the 1 in 60 rule and assume 1 dot equals 2°. At the time of the observation, the aircraft was on the
