Flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals What is the most common geodetic reference system with global coverage? WGS 84 What is meant by "dead reckoning"? Determining position based on known speed, course and elapsed time What is meant by "course" in relation to aircraft movement? The direction over the ground the aircraft is moving What is considered an integrity risk in relation to navigational performance? That undetected navigational system errors results in hazardously and misleading information to an aircraft On what frequency band is the DME operating on? UHF What is an advantage with the NDB? The low operating frequency allow reception beyond line of sight How does the VOR create the different radials? By transmitting 2 signals with different phases What information does the pilot get from a NDB? Direction only to the station What is a disadvantage of the NDB? The signal is subject to interference and reflections What airborne equipment is required to make use of a VDF? A VHF radio What principle is used in VOR bearing measurements? Phase comparison
