PHAK Chapter 17: Navigation

Question 1

What are the two most common ways to navigate?

Answer 1

Pilotage
Dead Reckoning

Question 2

What is Pilotage?

Answer 2

Navigation by visual reference to landmarks or checkpoints.

Question 3

What is Dead Reckoning?

Answer 3

Navigation solely by means of computations based on time, airspeed, distance, and direction.

Question 4

What does GPS stand for?

Answer 4

Global Positioning System

Question 5

What is GPS?

Answer 5

A satellite-based radio navigation system used to establish position. Three satellites are used to triangulate a position, a fourth satellite verifies position.

Question 6

What does DME stand for?

Answer 6

Distance Measuring Equipment

Question 7

What is DME?

Answer 7

Measuring device that uses ground and air components to determine the slant range of an aircraft from a point, measured in nautical miles.

Question 8

What does VOR stand for?

Answer 8

Very-High Frequency Omnidirectional Range

Question 9

What does a VOR do?

Answer 9

Provides 360° azimuth information in the form of radials expressed in magnetic heading.

Question 10

What are the 5 C’s of the lost in-flight procedure?

Answer 10

Climb - Climb for a better view of your surroundings.
Communicate - Communicate with ATC or FSS.
Confess - Admit you are lost.
Comply - Comply with what ATC tells you.
Conserve - Conserve fuel.

Question 11

Turning and Acceleration Compass Errors:
Northerly Turning Errors

Answer 11

When starting a turn from a northerly heading, the compass indication lags behind the turn.

Question 12

Turning and Acceleration Compass Errors:
Southerly Turning Errors

Answer 12

When starting a turn from a southerly heading, the compass indication leads the turn.

Question 13

Turning and Acceleration Compass Errors:
The acronym for Compass North/South turning errors.

Answer 13

UNOS
Undershoot North Overshoot South

Question 14

Turning and Acceleration Compass Errors:
Acceleration on an East or West heading.

Answer 14

When accellerating on an East or West heading, the error appears as a turn indication toward North.

Question 15

Turning and Acceleration Compass Errors:
Deceleration on an East or West heading.

Answer 15

When decelerating on an East or West heading, the error appears as a turn indication toward South.

Question 16

Turning and Acceleration Compass Errors:
The acronym for Compass North/South acceleration and deceleration errors.

Answer 16

ANDS
Accelerate North Decelerate South

Question 17

6 Compass Errors

Answer 17

VDMONA
Variation
Deviation
Magnetic Dip
Oscillation
Northerly Turning Errors
Acceleration Errors

Question 18

VOR Instrument: Course Deviation Indicator

Answer 18

Determines an aircraft’s lateral position in relation to the selected course.
If the aircraft’s location is left of this course, the needle deflects to the right, and vice versa.

Question 19

VOR Instrument: To/From Indicator

Answer 19

Shows if the course selected will take you toward or from the desired VOR station.

Question 20

VOR Instrument: What does OBS stand for?

Answer 20

Omni-Bearing Selector

Question 21

VOR Instrument: What is the OBS knob used for?

Answer 21

Knob used to rotate a compass card to select a course to follow.

Question 22

VOR Instrument: Deflection

Answer 22

Shows how many degrees the plane is off the selected radial. Each dot represents two degrees of deviation.

Question 23

What is a VOR used for?

Answer 23

Navigation.

Question 24

What is the tolerance for VOR accuracy?

Answer 24

A pilot can perform a VOR ground or air check to confirm VOR accuracy.
Acceptable accuracy:
* ± 4° for ground checks.
* ± 6° for airborne checks.

Question 25

What are the three types of aeronautical charts used by VFR pilots?

Answer 25

Sectional
VFR Terminal Area
World Aeronautical
