Cross Country Flight Planning Flashcards
the 3 most common ways to navigate are
Pilotage, dead reckoning, or radio nav
what is pilotage
visible landmarks used for navigation
what is dead reckoning
navigational use for finding position by computing direction and distance from a known point
what is the most common aeronautical chart to use in VFR Navigation
sectional chart
are electronic flight bags (EFBs) approved for use as replacement for paper reference materials in the cockpit?
yes
what is an isogonic line
on most aeronautical charts, broken magenta lines that connect points of equal magnetic variation
what is magnetic variation
angle between true north and magnetic north
what are the limitations (if any) to VOR reception distances)
they are subject to line-of-sight restrictions and the range varies based on the altitude of the receiving equipment
what are the different methods for checking the accuracy of VOR receiver equipment
VOT check (+/- 4), ground checkpoint (+/- 6), airborne checkpoint (+/- 6), dual VOR check (4 degrees between each other), and a selected radial over a known ground point (+/- 6)
what is a distance measuring equipment (DME)
used to measure, in nautical miles, the slant range distance of an aircraft from the DME
brief description of Global Positioning System (GPS)
satellite based radio nav system that broadcasts a signal used by receivers to determine a precise position
how do you convert true direction to magnetic
note the variation by the nearest isogonic line
what is the saying relating to the isogonic lines when correcting true to magnetic
east is least (subtract) west is best (add)
what are lines of latitude
lines running east and west
what are lines of longitude
lines drawn from the North Pole to the South Pole as right angles to the equator
what is magnetic deviation
due to magnetic influences within the airplane itself (radios, tools, engine, etc.) the compass needle is frequently deflected from its normal reading
name several types of navigational aid
VOR, VORTAC, DME, RNAV, GPS
what is a VOR or VORTAC
radio stations that project radials in all directions from the station
within what frequency range do VORs operate
in the VHF band between 108 and 117.95 MHz
what is a VOR radial
a line of magnetic bearing extending from an omnidirectional range (vOR)
how are VOR NAVAIDs classified
terminal, low, and high
what are 3 functional elements of GPS
space element (30 satellites), control elements (network of ground based stations, and user element (antennas and reviewer processors)
what are the different types of GPS receivers
differs from VFR flight and IFR flight
what is the purpose of RAIM
receiver autonomous integrity monitoring is self-monitoring function performed by GPS receiver to ensure adequate GPS signal is received
