Aviation Navigation Systems Quiz

Which ground-based navigational system uses a radio transmission from fixed ground beacons to determine position?

• Non-Directional Beacon (NDB)

• Inertial Navigation System (INS)

• Instrument Landing System (ILS)

• Very High Frequency Omni-Directional Range (VOR)

Which type of VOR station would be used by an aircraft flying at 10,000 feet and 40 nautical miles from the station?

• Terminal VOR Station

• Low-altitude VOR Station

• High-altitude VOR Station

• Mid-altitude VOR Station

Which of the following is a limitation of the VOR system?

• VOR is unreliable during precipitation

• VOR transmissions have a limited range

• VOR transmissions are only received if the aircraft is within line-of-sight

• VOR signals cannot be received when the aircraft is below radar range

What was the Inertial Navigation System (INS) originally developed for?
