What are the units of Time?
Hours/minutes/seconds UTC (Universal Time Coordinated)
What is the definition of navigation?
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of an aircraft or vehicle from one place to another.
What factors determine the type of navigation that a pilot will use? (There are 7 total)
Where the flight is going, the flight distance, when the flight is to depart, the type of aircraft, the on-board equipment, the pilot’s licence and the expected weather.
What is the oldest and simplest form of navigation?
Visual navigation.
What are the 6 types of navigation?
Visual, Celestial, Compass & Clock, Radio-based, Inertial Navigation Systems and Global Navigation Satellite Systems (GNSS).
What is Celestial navigation?
Celestial navigation is by means of using the starts to determine direction of travel or a global position.
What instrument developed in the 1730s determined longitude using celestial navigation?
A sextant
What instrument developed in the 1760s determined latitude using celestial navigation? (In this case, position of the sun)
A Chronometer
How does Compass navigation work?
A freely suspended compass needle will align to magnetic north. This allows the ability to plot a course from one point to another and follow it regardless of visibility.
What is an NDB?
What do NDBs do?
What is their range?
A Non-Directional Beacon.
An NDB provides aircraft with a basic reference for them to fly towards or from.
They are usually sited in the vicinity of aerodromes with ranges of about 30NM.
What is a VOR?
What do they do?
What is their range?
VHF Omni-directional Range.
They provide aircraft with an accurate radial to fly, to or from the VOR.
They have ranges up to 200NM.
What is an ILS?
What do they do?
What is their range?
An Instrument Landing System.
They are an approach aid that radiates radio signals to provide aircraft with horizontal and vertical guidance to a runway for landing.
They have horizontal ranges of 25NM and vertical ranges of 10NM.
How does an Inertial navigation system work?
The systems use gyros, accelerometers and computers to monitor movement and track the position of the aircraft.
What does the acronym GNSS mean?
Global Navigation Satellite Systems
How do GNSSs work?
Satellite navigation utilises orbiting satellites to provide position information by using trilateration. They can also be used anywhere on Earth in all-weather conditions.
