ATSEP BASIC – NAV QUESTIONS AND ANSWERS
What is variation? - Answers- The difference between true and magnetic north
What is meant by instrument flight rules? - Answers- 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? - Answers-
WGS 84
What is a disadvantage of the NDB? - Answers- The signal is subject to interference
and reflections
What airborne equipment is required to make use of a VDF? - Answers- A VHF radio
What principle is used in VOR bearing measurements? - Answers- Phase comparison
What elements are required for a ILS? - Answers- LOC, GP and markers or DME
What information does the pilot get from the glide path? - Answers- The correct vertical
decent profile
Of what use, if any, can a military TACAN be used by civilian aircraft? - Answers-
Civilian aircraft can use the DME part
What is meant by "dead reckoning"? - Answers- Determining position based on known
speed, course and elapsed time
What is meant by "course" in relation to aircraft movement? - Answers- The direction
over the ground the aircraft is moving
What is considered an integrity risk in relation to navigational performance? - Answers-
That undetected navigational system errors results in hazardously and misleading
information to an aircraft
On what frequency band is the DME operating on? - Answers- UHF
What is an advantage with the NDB? - Answers- The low operating frequency allow
reception beyond line of sight
How does the VOR create the different radials? - Answers- By transmitting 2 signals
with different phases
What information does the pilot get from a NDB? - Answers- Direction only to the
station
