# Navigation Flashcards

What is Pilotage?

Navigating by reference to landmarks

What is Dead Reckoning?

Navigating based on calculations of time, speed, distance and direction.

What is a Line of Position (LOP)?

A straight line between two points where an aircraft can possibly be located.

What is a Fix?

The intersection of two Lines of Position (LOPs)

Define True Course:

Course between two points referenced to True North

Define Magnetic Variation:

The angular difference (expressed in degrees) between True North and Magnetic North at a particular place on the earth’s surface.

How can you determine Magnetic Variation along your route of flight?

Look for magenta Isogonic lines on the sectional chart.

Define Magnetic Course:

It is True Course corrected for Magnetic Variation

Define Wind Correction Angle:

The difference in degrees between Magnetic Course and Magnetic Heading.

How do we correct True Course for Magnetic Variation?

- If the Magnetic Variation is EAST then SUBTRACT the variation value from the True Course.
- If the Magnetic Variation is WEST then ADD the variation value from the True Course.

Define Magnetic Heading:

Magnetic Course corrected for wind

Define Compass Deviation:

Compass errors caused by the magnetic fields of items inside the aircraft such as radios or navigation equipment.

Define Compass Heading:

Magnetic Course corrected for Compass Deviation

When must you fly at VFR Cruising Altitudes?

Whenever you are in level cruise flight more than 3,000 feet AGL

VFR Cruise Altitudes are based on what course?

Magnetic Course
