Radios Flashcards
Primary surveillance radar (PSR)
Displays reflected radio signals from contacts like aircraft and weather without requiring any information from the aircraft.
Secondary surveillance radar (Ssr)
Requires a reply from my transponder, known as an interrogation, to determine the aircraft range. Significantly improved range over PSR. The method does not determine the position of an aircraft without a transponder and it does not locate weather
RNAV
Area navigation (RNAV) can be defined as a method of navigation that permits aircraft operating on any desired force within the coverage of the station reference navigation
Direct to means no airways required.
RNAV was developed to provide more lateral freedom and thus more complete use of available airspace
RNAV Advantage
This method of navigation does not require a track directly to or from any specific radio navigation aid, and has three principal applications:
A route structure can be organized between any given departure and arrival point to reduce flight distance and traffic separation
Aircraft can be flown into terminal areas on varied preprogrammed arrival and departure paths to Expedia eight traffic flow; &
Instrument approaches can be developed and certified at certain airports without local instrument landing eats at that airport
VOR/DME
Common type of general aviation Arnav system is the track line computer (TLC) based on azimuth and distance information from a Vortac
TACAN
Tactical air navigation is a Navaid used primarily by the military for all route, nonprecision approaches, and other military applications.
It works like a VOR/DME
It provides azimuth in the form of radios and slant distance in nautical miles from the ground station
It operates in UHF Range, there are 126 channels.
TACAN users be obtained distance information from a DME installation by selecting the receivers to the TACAN channel that is paired with the VOR frequency.
Pilots are cautioned that only DME information is being received from a Tak can. Any apparent radio information obtained through a couple VOR receiver can only be false information
You must use military equipment to take advantage of tacan range, radio speed, and bearing
Radar altimeter
Provides the pilot with dependable accurate height above ground level. It provides the absolute altitude
Receiver transmitter
The core of this device, a radio altimeter, is a single frequency radar system the broadcast a pulsed tone directly downward.
What time it takes for the reflected tone to be received directly translates into the aircraft side above the terrain
Precision approach radar (PAR)
Used by military only. Aircraft can be talked down to the runway by controller with two radar screens. One horizontal and the other vertical. There are probably none left in Canada
Flight Director system
A flight Director system is a sophisticated system that electronically collects information provided by a number of instruments. The system combines a horizontal situation indicator (HSI) and an altitude Director indicator (ADI)
• What does a FD do? Intercept a radial inbound to a VOR or ILS. Give pitch commands for a missed approach. Give guidance on procedure turns. • Calculates the crab angle to correct for wind. Calculates when to roll into and out of a bank, • When a pilot is not using the FD it is called using "raw data.
Airborne collision avoidance systems
ACAS - Airborne collision avoidance system
TCASN traffic alert and collision avoidance system
Both receive SS are equipped aircraft transponder and the computer calculates if there is a chance of a collision
Display for the TCAS is usually over the top of the VSI and has voice prompts
