Navigation and Cross Country Flashcards
What is true course
The A/C course over the ground relative to true north
How do you determine a magnetic course
You take your true course, correct it for wind to get your true heading, then add for west or subtract for each magnetic variation to get the magnetic heading
What is true heading
True course corrected for wind
What is magnetic heading
It is your direction relative to magnetic north read from your magnetic compass
True heading corrected for variation
What is a compass course
Course corrected for deviation and variation
What is compass heading
Magnetic heading corrected for deviation
How do you determine variation?
Isogonic line closest to your course
What is deviation
Error induced in a compass by local magnetic fields
What are isogonic lines
imaginary line on a map joining points on the earth’s surface at which the magnetic declination is the same
What are agonic line
an imaginary line around the earth passing through both the north pole and the north magnetic pole at any point on which a compass needle point to true north
What is a restricted area?
Areas denoted the existence of unusual, often invisible, hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles. Penetration of restricted areas without authorization from the using or controlling agency may be extremely hazardous to the aircraft and its occupants
What is a prohibited area
Airspace of define dimensions identified by an area on the surface within which the flight of A/C is prohibited. Such areas are established for security or other reasons associated with the national welfare
Can you fly through a restricted or a prohibited area
You can fly though a restricted area with prior permission, usually obtain on the ground, from the controlling agency. You cannot fly in a prohibited area, however, you might be able to fly above it. Check the the special use airspace table on the sectional to find the dimensions of SUA.
What are warning and alert areas
Warning area is airspace of defined dimensions, extending from three NM outward from the coast of the US, that contains activity that may be hazardous to nonparticipating A/C. It is established to warn pilots of potential danger. It can be over domestic, international, or both waters
And alert area are depicted on charts to inform nonparticipating pilots of areas that may contain a high volume of training or an unusual type of aerial activity. Pilots should be particularly alert when flying in these areas
Where can you find information regarding an airports location, number of runway, services, and traffic patterns
The US Chart Supplement
Where can you find ATC procedures
Aeronautical Information Manual
When do charts expire and how can you tell
They expire every 56 days with the valid period being printed on the cover
What is a road
single or double gray lines
What is a river
Dark blue lines filled with light blue
What is a town
Yellow areas (pop 250K or more), squares 25K-250K, or dots less than 25K
What is a lake
Large blue area in the general shape of the real lake
