Navigation, Flight Planning, and Procedures Flashcards
What is an RMI?
Radio magnetic indicator
Shows bearing to an NDB or VOR
What is an ADF?
Automated direction finder
Aircraft instrument which allows tracking to NDBs
What is an HSI?
Horizontal situation indicator
Combines heading indicator with CDI
What are some types of radio aids to navigation?
VOR NDB RNAV DME GPS
What are characteristics of a VOR or VORTAC?
VHF frequency, projected in 360 radials
VORTAC provides DME information
Some offer voice reception capability
What are the methods for performing a VOR check?
VOT check +/-4* Ground checkpoint +/-4* Airborne checkpoint +/-6* Dual VOR check 4* between each other Selected radial over known ground point +/-6*
Where can locations of VOTs, ground VOR checkpoints, and airborne VOR checkpoints be found?
Chart supplement (AFD)
How can you determine if a VOR or VORTAC is out of service for maintenance?
Audible, coded information is removed
What is DME?
Distance measuring equipment
Transmitted by VORTACs on UHF frequencies (960-1215 MHz)
Provides slant-range distance to and from station
What is the range of DME?
Reliable up to 199NM
What is an NDB?
Non-directional beacon190-535 kHz (below AM radio)
Allows for homing to the station
What is RNAV?
Area navigation
INS, LORAN, VOR/DME, GPS
What is GPS?
Global positioning system
Uses information from multiple satellites to determine position
What is primary radar?
System in which radar signal is reflected off the aircraft
What is secondary radar?
Radar signal is received and returned by a transponder
Describe Terminal Radar Approach Control (TRACON).
30nm radius from facility, up to 10000’ MSL
Should be addressed as “Approach” unless directed otherwise (Departure)
Describe Air Route Traffic Control Center (ARTCC).
Provide separation for IFR enroute flights
Divided into sectors, and high and low altitude operations
Have numerous transmitters to ensure signal reception
Can a handheld GPS receiver be used as the primary means of navigation on a VFR cross country flight?
Yes, but it should be supplemented with another form of navigation
What are some potential hazards of using only GPS navigation?
Satellite outages
RAIM capability
Database currency
Antenna position
What preflight preparations are required when using GPS navigation on an IFR flight?
GPS properly installed and certified Database current GPS and WAAS NOTAMs RAIM availability for non-WAAS units Operational status of ground-based NAVAIDs
What is the maximum elevation figure (MEF) on a sectional chart?
MSL elevation of highest terrain feature or obstacle within a specific quadrant
What preflight information are pilots required to be aware of for any flight not in the vicinity of an airport?
Weather reports and forecasts Fuel requirements Alternatives Known ATC traffic delays Runway lengths of intended use Takeoff and landing distance data
What are the 4 most common ways to navigate?
Pilotage
Dead reckoning
Radio navigation
GPS
Define isogonic line.
Line connecting points of equal magnetic variation
