Phrases Tested Flashcards
AGL
Above ground level altitude
Altitude expressed in feet measured above ground level
ATC
Air traffic control.
A service operated by appropriate authority to promote the safe, orderly and expeditious flow of air traffic
ATCS
Air traffic control specialist.
A person authorized to provide air traffic control service
ALT
Altitude.
The height of a level, point or object measured in feet above ground level (AGL) or from mean sea level. (MSL)
UTC
Coordinated universal time.
Time is given in coordinated universal time, the local standard time at the prime meridian at Greenwich England. local standard time is based on each 15° of longitude
DME
Distance measuring equipment. Equipment (airborne and ground) used to measure in nautical miles, the slant range distance of an aircraft from the DME navigational aid
FL
Flight level.
A level of constant atmospheric pressure related to a reference datum of 29.92 inches of mercury. Each is stated in three digits that represents hundreds of feet. For example flight level FL250 represents a barometric altimeter indication of 25,000 feet flight level FL255, and indication of 25,500 feet
NAVAID
Navigational aid.
Any visual or electronic device airborne or on the surface which provides point to point guidance information or position data to aircraft inflight
MSL
Mean Sea level.
Altitude expressed in feet measured from mean sea level
GPS
Global positioning system.
A space based radio positioning navigation and time transfer system. The system provides highly accurate position and velocity information, and precise time, on a continuous global basis, to an unlimited number of properly equipped users. The system is unaffected by weather, and provides a worldwide common grid reference system
NDB
Non directional Beacon.
An L/MF (low/medium frequency) or UHF (ultra high frequency) Radio begin transmitting nondirectional signals we are by 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
TACAN
Tactical air navigation.
An ultrahigh frequency the electronic rho-theta air navigation aid which provides suitably equipped aircraft in continuous indication of bearing and distance to the TACAN station
VOR
Very high frequency Omni directional range navigational aid.
A ground-based electronic navigation a transmitting very high frequency navigation signals, 360° in azimuth, oriented from magnetic north. Used at the basis for navigation in the national airspace system. The VOR periodically identifies itself by Morse code and may have an additional voice identification Feature. Voice features may be used by Atc or FSS for transmitting instructions/information to Pilots
Very high frequency Omni directional range/tactical air navigation navigational aid.
A navigation aid providing VOR azimuth, TACAN azimuth, and TACAN distance measuring equipment (DME) at one site.
VORTAC
Above ground level altitude
Altitude expressed in feet measured above ground level
