Chapter 9: Flight Navigation Flashcards
A grid can provide a system of ____ on a map
Coordinates
By reading across and down the grid to the point of ____, any location can be found
Intersection (coordinate point)
Relief is a term used to describe
Elevation
Relief on an aeronautical chart is depicted by
Contour lines, color tints, shading
Why is water a useful navigational aid?
Pilots can identify bodies of water by comparing its actual shape, as seen from the air, to the shape shown on the sectonal
Very small towns are shown by
A small black circle
Mines are charted as ____ and ____ ____.
Picks, sledge hammers
On a map, highways are printed as black or ____ lines
Magenta
Victor airways are based on the locations of ____ ____ stations called VORs
Radio navigation
What are the two types of airspace clearly marked on charts for pilots to avoid?
Prohibited and restricted airspace
What airspace is where military flight training activities are conducted?
Military Operations Area (MOA)
Low-level ____ ____ appearing on sectional aeronautical charts are called MTRs.
Training routes
Major factor that must be considered by navigators:
Determining the ____ line and the magnetic _____
True course, North (variation)
Major factor that must be considered by navigators:
Allowing for compass ____
Deviation
Major factor that must be considered by navigators:
Maintaining proper ____
Altitude
Major factor that must be considered by navigators:
Determining true ____
Airspeed
Major factor that must be considered by navigators:
Determining the wind ____ and ____ in order to correct for wind drift
Speed, direction
Navigating by visible landmarks is called
Pilotage
Step 1: Preparation for pilotage navigation
Drawing a true course line
Step 2: Preparation for pilotage navigation
Total distance to be flown is measured
and the TC line marked off in segments of 10 miles each (these distance segments help the pilot or navigator locate landmarks and determine the progress of the flight over unfamiliar territory)
Step 3: Preparation for pilotage navigation
Selecting land marks along the TC line to be used as checkpoints
Step 4: Preparation for pilotage navigation
Selecting “brackets” (easy-to-
see surface features to either side of the TC) to help maintain the proper course over the ground
What navigation involves the systematic consideration of all factors which will and could affect a flight?
Dead Reckoning
The ADF (Automatic Direction Finder) only shows the direction of a ____; it makes no allowance for the effects of ____.
VOR, wind
The DME shows the number of ____ ____ the airplane is from the radio station
Nautical miles
While weather radar does show areas of precipitation, it’s most important function is go show ____ ahead of aircraft
Thunderstorms
The nationwide VOR system consists of
directional broadcasting radio stations
Each VOR Station broadcasts what two signals?
One rotating and one stationary
The prime meridian is the starting point for
a. Latitude
b. Longitude
c. Gratitude
d. Projection
b. Longitude
The equator divides the northern and southern
Hemispheres
Half of a sphere
Hemisphere
The basic grid system of latitude and longitude lines is called
Graticule
A great circle is any circle on the earth’s surface that is made by a plane passing through its center.
TRUE
Any circle other than a great circle is a small circle.
TRUE
Coordinates are read first according to longitude and then according to latitude
FALSE
What are the broadest airport classifications?
Civil airports or military and joint-use airports
In joint-use airports, facilities aren’t necessarily shared by the military and civilians.
TRUE
Controlled airspace is serviced by
Air Traffic Controllers
The largest area of controlled airspace is called
The continental control area
High-altitude airways are clearly defined on sectional charts.
FALSE
Low-altitude airways are also known as Victor airways.
TRUE
The wind triangle is constructed to find the true heading that compensates for the effect of wind.
TRUE
As a navigational aid, the aircraft radio is a useful communication link with authorities who control aspects of navigational flight.
TRUE
The VOR allows pilots to fly directly to or from VOR stations.
TRUE
The VOR does not automatically compensate for the effects of wind
FALSE
