What chart is primarily for VFR pilot use?
Sectional chart
What is another name for visual navigation?
Dead reckoning
Or
Pilotage
Are charts oriented to true or magnetic north?
True north
What is magnetic variation?
Angular difference between true and magnetic north
What is magnetic deviation?
Error in the compass caused by stray magnetic fields.
What are isogonic and agonic lines?
Isogonic lines are lines of equal magnetic deviation
Agonic lines are lines of NO magnetic deviation
What is a VOR?
Radio NAVAID (navigational aid) that gives course information
Name some gyroscopic instruments
Artificial horizon (attitude indicator)
Heading indicator
Turn and bank indicator (turn coordinator)
How many courses does a VOR give?
Infinite number, but we think of it as 360
Is the VOR aligned to true or magnetic north?
Magnetic north
What is the guaranteed service volume for each VOR class?
Terminal
Low
High (4 that vary by altitude)
Terminal - 25
Low - 40
High below 14,500 - 40
14,500 to 17,999 - 100
18,000 to FL450 - 130
Above FL450 - 100
What letters begin low altitude and high altitude airways?
Low V, called “victor twenty seven” V27
High J, called “jay four” J4
At what altitude do jet routes begin?
18,000 feet MSL (mean sea level)
What is the margin of error for a VOR radial?
6 degrees
How does DME figure distance from the NAVAID?
Slant range - direct line to the NAVAID
