XC Flight Planning Flashcards
What are three ways to navigate?
Dead reckoning - by computing direction and distance from a known location
Pilotage - by reference to visual landmarks
Radio navigation - using VORs
What is an isognic line
A line that indicates the amount of magnetic variation between the earth’s poles.
What are lines of latitude and longitude?
Longitudes run east and west as meridians, originating in Greenwich, UK. Latitudes run parallel to the earth North and south of the equator.
What is magnetic deviation?
Because of objects located within the aircraft (radios, instruments, etc.) magnetic deviation causes the magnetic compass to deflect from its actual heading.
Describe what a VOR is
VORs are radio stations that beam 360 radials in all directions, acting as a navigational aid for VOR equipped aircraft.
How far can one expect to get a signal from a VOR
SMO VOR is Class L, which is about 40 miles of range.
How does GPS work? What are the functional elements?
A systems of satellites that work together to determine an object’s precise location.
1) Space - 30 satellites sending signals to the earth
2) Control - ground based system verifying the accuracy of the space elements.
3) User element - antennas and on-board receiver processes that provide on-board positioning, velocity and precise timing to the user
What is RAIM
Receiver Autonomous Integrity Monitoring is a self monitoring feature of a GPS receiver that ensures its receiving an accurate, adequate reading at all times.
How many satellites does a GPS Sytem use?
4 satellites will result in latitude, longitude, and altitude
5 satellites allow for all of the above, plus RAIM capability
What is a VFR waypoint
On a VFR flight using pilotage, a VFR waypoint assist with positional awareness. They begin with VP and are retrievable from navigation databases.
What is a CTAF
Common traffic awareness frequency is the best method of communicating with traffic at an non-towered airport. A CTAF can be a UNICOM, MULTICOM, or FSS.
If there is not UNICOM or FSS at an airport, what frequency should you contact?
Contact the MULTICOM on 122.9 for self-announce procedures.
What restrictions regarding alcohol use applies to pilots?
No pilot may consume alcohol within 8 hours of a flight
No pilot may have a BAC greater than .04 and act as a crew member.
Which persons on an airplane need to use a seatbelt?
A person must occupy a seat and wear a seatbelt during ground movement, takeoff and landing.
When do crew members need to have their seatbelt operated?
While at their station.
