What is a true course line?
a line or series of lines that the navigator indicataes the airplane will follow
What is magnetic courses?
Magnetic north is different from true north because the magnetic north and south poles are not the same a the geographic north and south poles
When does compass deviation occur?
Once the compass is mounted in a plane. It must be adjusted because of electrical power and metals in the aircraft
what is a altimeter?
The only non-electronic means the pilot has of determining the distance over the service
what is true airspeed vs. ground speed?
airspeed tells the pilot how fast the airplane is flying through the air. Ground speed is a measure of how fast your aircraft is going across the surface of the earth
What does wind do?
effect of wind on an airplane can either increase or decrease the ground speed depending on whether the plane is flying with or against the wind
What is a wind triangle?
a tool pilots use to figure out where the wind drift will cause the aircraft to fly over the ground.
What does pilotage mean?
navigating by reference to visible landmarks
What does Dead Reckoning involve?
the systematic consideration of all factors that will and could affect the flight
What is the aircraft radio used for?
an aid to navigation because it is the pilot's communication's link with faa personal
What does VOR stand for?
Very High Frequency Omnidirectional radio Range
What is the VOR?
is the second half of the aircraft radio.
What must the VOR be tuned to?
the broadcast frequency of the Vor radio station just like the aircraft radio
What does ADF stand for?
Automatic Directional Finder
What is the ADF? i
is another type of radio receiver that is used to determine direction, but it does not provide as much information as the VOR
What does DME stand for?
Distance measuring equipment
What does the DME do?
sends a signal and measures the time it takes to go from the aircraft to the VORTAC and return.
Radar works on the principle of what?
of reflected radio energy.
What do weather radars show?
areas of precipitation and storms
What does the VOR system do?
The total system includes the airplane receivers and the ground stations working together to help the pilot navigate.
what does LORAN stand for?
Long-range navigation
What is LORAN?
It is a complete navigation system that is used by large cargo ships and many small, privately owned sea craft. It is also used by aircraft as a means of navigation.
What is GPS?
Consists of roughly24 satellites in orbit around the Earth, several ground tracking stations and a receiver in the aircraft.

is the civilian public's signal
What does SPS stand for?
Standard positioning system
What is inertial navigation?
is a self contained unit located withing the aircraft that needs only to be programmed for the starting point and a destination
What does RNAV stand for?
Area Navigation system
What is RNAV?
is a computer controlled navigation system that allows pilots to fly directly from the airport of origin to the destination airport without passing over a single VOR station
What does ILS stand for?
Instrument Landing System
What is ILS?
is used only within a short distance from the airport and only when the purpose is to land the airplane
