Blk 4 General Navigation Flashcards
VOR
Very High Frequency (VHF) Omni Range
360 degree “radials”
VOR does not provide any distance information
DME
Distance Measuring Equipment
UHF Band. co-located with other NAVAID (VOR or ILS)
TACAN
Tactical Air Navigation
UHF Band. 360 degree “radials”. TACAN is UHF whereas VOR is a VHF. TACAN has built in DME capability. Used only by Military
VOR/DME
Both transmitters co-located and operated simultaneously. Operation is identical
VORTAC
VOR and TACAN transmitters co-located and operated simultaneously. Similar to VOR/DME except that DME signal is transmitted from the TACAN
Civilian aircraft will receive the radia signal from the VOR transmitter and the DME signal from the TACAN transmitter.
Military aircraft can receive radial signals from either transmitter depending on which frequency is selected
NDB
Non Directional Beacon
AM (Amplitude Modulated) radio band. No specific radials being transmitted.
ILS
Instrument Landing System (VHF System)
Localizer, Glide Slope, DME, Marker Beacons.
Up to 4 separate NAVAID signals working together. Each signals/components is automatically tuned when the ILS frequency is selected on the AC nag radio.
Localizer
VHF Band. Horizontal signal. Aligns the AC with the runway during final.
Glide Slope
UHF Band. Vertical signal. Guide the AC down a descent path that is CLEAR OF OBSTACLES down to the decision height for the approach.
DME
UHF Band. Same function as enroute NAVAID, simply co-located with the ILS system
Marker Beacons
Provide situational awareness during final approach. Xmit a signal straight up in an elliptical pattern. 3 different marker beacons in ILS system
Outer, Middle and Inner Marker
Outer Marker (OM)
Passing overhead the outer marker is indicated in the AC by a BLUE light w/ “O” flashing and audible Morse code
Middle Marker (MM)
Passing overhead the middle marker is indicated in the AC by an Orange light w/ “M” flashing and audible Morse code
Inner Marker (IM)
Passing overhead the inner marker is indicated in the AC by a White light w/ “I” flashing and audible Morse code
Localizer Frequency Signals
90Hz Left and 150Hz Right
Glide Slope Frequency Signals
90Hz Top and 150Hz Bottom
1000ft from the Runway Threshold, crossing the runway threshold at 50ft.
Aircraft Navigational Equipment
VHF navigation, glide slope, TACAN, ADF, DME and marker beacon receivers.
VHF Navigation System
Capable of receiving Very High Frequency Omni-range (VOR) signals VOR provide bearing info and display it on HSI or RMI. HSI may also display a pointer that displays flight direction either TO or FROM the Nav station.
Glide Slope System
(UHF) Automatically tuned whenever an ILS Localizer freq is selected on the VHF nav radio. Glide Slope displays deviation indications on the ADI or HSI during ILS approaches only
TACAN System
Tactical Air Navigation
Determine the relative bearing and distance to a selected station. TACAN receiver is the only nag receiver capable of determining distance from the radio station. TACAN and VOR are similar
ADF System
Automatic Direction Finder
Capable of receiving bearing info from a NDB for display on the RMI. Bearing pointer on the RMI shows the direction to the station.
Distance Measuring Equipment
DME. Receives a time coded signal from DME xmitter and calculated the time it took to reach the AC. Thats converted to a distance in NM and displayed on the DME readout.
Marker Beacon Receiver
Illiminate lights and trigger aural signals when the AC flies over the OM, MM or IM beacon emitters during ILS approach
Radio Magnetic Indicator
RMI - Will give the crewmember the best picture of the AC position in relation to a NAVAID.
Radial Signal
Is a magnetic bearing extending OUTWARD from a VOR, VORTAC or TACAN navigation facility.
HSI
Horizontal Situation Indicator
Combination of a heading indicator, Radio Magnetic Indicator, course indicator and range indicator (DME).
HSI Displays
heading, desired course, course deviation, bearing, range, and direction of flight TO or FROM a NAVAID.
FLIP
Booklets containing approach and departure information are called DOD Flight Information Publications. Color represents specific world region
Enroute FLIP
Provide basic airfield information and flight procedures, airfields, ICAO identifiers, runway information, types of ground support, specific restrictions, cautions, available navigation aids, list of radio frequencies.
Terminal FLIP
Essential departure and arrival procedures. Contain airport diagrams, instrument approach procedures, SID, radar instrument minimums, and START.
Low Altitude Terminal FLIP
Procedures bellow 10,000 feet
High Altitude Terminal FLIP
Procedures above 10,000 feet
TCN
Terminal Change Notices
Published at the midpoint of each FLIP cycle, usually 4 weeks. Contains only SID, STAR, IAP, Radar Minimums, and airport sketches that have changed or been added since publication of the current FLIP.
