A _________ is any electronic device, airborne or on the surface, which provides point to point guidance information or position data to aircraft in flight.
radio navigational aid
_______ is an L/MF radio beacon transmitting non-directional signals whereby the pilot of an aircraft equipped with direction finding equipment can determine his bearing to or from the radio beacon and “home” on or track to or from the station.
Non-directional Radio Beacon (NDB)
What operate on L/MF, transmit continuous 3 ltr identification in Morse Code except during voice transmissions?

Class T is _____ and below, ___ miles.
12,000; 25
Class L is below ______, ___ miles.
18,000; 40
Class H is divided into 4 different ranges, name them all.

14,500 - 17,999 —- 100 miles
18,000 - FL450 —- 130 miles
Above FL450 —- 100 miles
How do you identify a VOR?
by its Morse Code identification or by the recorded automatic voice identification which is always indicated by use of the word “VOR” following the name
- periods of maintenance, facility may radiate a T-E-S-T code or the code may be removed
What is the accuracy of course alignment of the VOR?
plus or minus 1 degree
______ is an ultra high frequency electronic navigation aid which provides suitably equipped aircraft continuous indications of bearing and distance to the TACAN station.
Tactical Air Navigation (TACAN)
Tacan uses what frequency?
Ultra high frequency UHF
The ____ is more accurate than a ____ and is physically much smaller.
TACAN ; VOR
T/F: Tacans generate directional info and transmit it by ground equipment to the aircraft providing 360 magnetic radials.
True
______ is equipment (airborne and ground) used to measure, in nautical miles, the slant range distance of an aircraft from the DME Navigational aid.
Distance Measuring Equipment (DME)
The difference between slant range and horizontal distance is greatest where?
Near the NAVAID, at high altitude
When it comes to DME, is the interrogator in the aircraft or on the ground?
In the aircraft
DME operates on what frequency?
UHF
________ is a navigational aid providing VOR azimuth, TACAN azimuth, and TACAN distance measuring equipment (DME) at one site.
VHF mono directional range/tactical air navigation (VORTAC)
What 3 individual services does a VORTAC provide at 1 site?
- VOR azimuth
- TACAN azimuth
- TACAN distance (DME)
The frequency channels of the VOR and the TACAN AT EACH _______ facility are paired to simplify airborne operation.
VORTAC
DME distance is displayed ________.
As a slant range distance
What DME equipment on the ground is required to respond to the aircraft interrogator?
Transponder
The ILS is designed to provide: (2)
- approach path with both course and altitude guidance
- exact alignment and descent of an aircraft on final approach to a specific runway
The directional transmitters for the ILS are what?
Localizer and glide slope transmitters
Name the 4 parts of an ILS:
- localizer: provides horizontal (lateral) guidance along the extended centerline of the runway
- glide slope: provides vertical guidance along the descent path toward the runway touchdown point
- marker beacons: range information along the approach path (distance to threshold info)
- compass locator: low power, low or med frequency (l/mf) radio beacon installed at the site of the outer or middle marker
T/F: Where a complete ILS system is installed on each end of a runway, the ILS systems are not in service simultaneously.
True
The approach course of the localizer is called the ________.
Front course
Where is the localizer signal transmitted from?
Departure end of the runway
The localizer sends out how many radials?
1
Ils approach is not usable if ______ is out of service.
Localizer
Glide slope
Provides the pilot with vertical guidance to the runway in the direction of the localizer.
Marker beacons
Identify particular locations on the approach to an instrument runway; 3watts or less and produce an elliptical pattern
Describe location and size of marker beacons.
At 1000 ft above the antenna; 2400 width; 4200 length
What provides the basic means to transition from instrument flight to visual flight for landing?
Approach lights
Inertial navigation system (ins)
Self contained nav system; provides position and nav info in response to signals resulting from inertial effects
What is the ins comprised of?
Gyros, accelerometers and Nav computer
