Unit 9 Flashcards
Latitude
parallel to the equator (0º - 90ª)
Longitude
connect north pole → south pole
(mark direction of true north & south) (0º - 180º)
What is another name for longitude lines?
meridians
Day
time required for Earth to make 1 revolution of 360º
(Earth revolved at 15º/hour)
What are meridians used for?
Used to measure direction from one point to another in degrees from true north
Draw a line from departure point to destination & measure angle that line forms with meridian (at midpoint of course)
True course
course measure on sectional chart
Variation
angle between true north and magnetic north

Which airspaces are not depicted on sectional charts?
A & G
Restricted areas (R)
unusual, often invisible, hazards exist
Flying not prohibited but subject to restrictions (must get permission to fly)
Warning areas (W):
activity that be hazardous to nonparticipating aircraft (aerial gunnery)
Military operations (MOAs)
airspace established to separate certain military training activities from IFR traffic
(Contact FSS within 100 mi of area)
Alert area
high volume of pilot training or unusual type of aerial activity
Airports with fuel service
small solid squares at top & bottom of airport symbol
Advisory circulars (ACs)
provide systematic means for issuing non-regulatory material of interest to aviation public
FAA circulars
Airmen

Chart supplement
directory of all airports, seaplane bases, and helicopters open to public
A UNICOM
provides automated weather, radio check capabilities, & airport advisory information (by microphone clicks)

NOTAM
time critical aeronautical info of temporary nature
NOTAMs (D)
aeronautical facility, civil airports, en route NAVAIDs, services, procedures, hazards
FDC NOTAMs
flight restrictions, changes to airspace use, changes to air traffic service routes, changes to instrument flight procedures
Pointer NOTAMs
logically direct research by highlighting specific keywords
SAA NOTAMs
issued when special activity airspace (SAA) will be active outside published schedule times
Military NOTAMs
military NOTAMs are different format
Which sources of aeronautical information, when used collectively, provide the latest status of airport conditions (e.g., runway closures, runway lighting, snow conditions)?
Chart supplements and (D) NOTAMs
