Question 1

There are three radio navigation systems available for use for VFR navigation. These are:

Answer 1

VOR, NDB, GPS

Question 2

What does VOR stand for?

Answer 2

VHF (Very High Frequency) Omnidirectional Range

Question 3

What is a VOR?

Answer 3

VOR is a type of radio navigation system used by pilots it provides magnetic bearing information to determine their aircraft’s position TO and FROM a station, and stay on course.

Question 4

The VOR system is present in three slightly different navigation aids (NAVAIDs):

Answer 4

• VOR
• VOR/DME
• VORTAC

Question 5

What is a radial?

Answer 5

A radial is defined as a line of magnetic bearing extending outward from the VOR station.

Question 6

VORs and VORTACs are classed according to operational use. There are three classes:

Answer 6

• T (Terminal)
• L (Low altitude)
• H (High altitude)

Question 7

What are the normal usable altitudes and radius distances of a VOR/VORTAC Navaids.

Answer 7

Question 8

The following means are provided for pilots to check VOR accuracy:

Answer 8

• FAA VOR test facility (VOT)
• Certified airborne checkpoints
• Certified ground checkpoints located on airport surfaces

Question 9

What are the two components required for VOR Radio Navigation?

Answer 9

Ground transmitter and aircraft
receiving equipment.

Question 10

What does CDI stand for?

Answer 10

Course Deviation Indicator

Question 11

What does HSI mean?

Answer 11

Horizontal Situation Indicator

Question 12

What does ADF stand for?

Answer 12

Automatic Direction Finder

Question 13

What does RMI stand for?

Answer 13

Radio Magnetic Indicator

Question 14

What does DME stand for?

Answer 14

Distance Measuring Equipment

Question 15

What is bearing?

Answer 15

Refers to the direction or angle from a specific point, usually the aircraft, to a VOR station.

Question 16

Answer 16

DME

Question 17

Answer 17

NDB (Non Directional Beacon)

Question 18

Answer 18

TACAN

Question 19

Answer 19

VOR/DME

Question 20

Answer 20

VORTAC

Question 21

What is a NAVAID?

Answer 21

NAVAIDS are radio stations installed on the ground that emit electromagnetic waves, which are used by onboard instruments to determine the current position of the aircraft and navigate.

Question 22

What is a GPS?

Answer 22

A GPS (Global Positioning Indicator) is a satellite-based navigation system that provides accurate location and timing information to aircraft anywhere in the world.

Question 23

What is true course?

Answer 23

The true course is the aircraft path over the ground referenced to true north.

Question 24

What is true heading?

Answer 24

The true heading is the direction the aircraft nose is pointing referenced to true north.

Question 25

What is variation?

Answer 25

Variation is the angle between true north and magnetic north

Question 26

What is pilotage?

Answer 26

Pilotage is the process of navigating an aircraft by using visual references on the ground.

Question 27

What is dead reckoning?

Answer 27

Dead reckoning is navigation solely by means of computations based on time, airspeed, distance, and direction.

Question 28

What is IAS (Indicated Airspeed)

Answer 28

Indicated airspeed (IAS) is the speed shown on the aircraft’s airspeed indicator. It tells the pilot how fast the plane is moving through the air.

Question 29

What is CAS (Calibrated Airspeed)?

Answer 29

Calibrated airspeed (CAS) is the indicated airspeed of an aircraft corrected for errors due to instrument imperfections and positional effects.

Question 30

What is True Airspeed (TAS)?

Answer 30

True Airspeed is the actual speed of the airplane through the air.

Question 31

What is Ground Speed (GS)?

Answer 31

It’s the speed at which an aircraft is moving relative to the ground. Ground Speed is true airspeed corrected for wind.
