VHF Omni−directional Range (VOR)
VORs operate within the 108.0 to 117.95 MHz frequency band and have a power output necessary to provide coverage within their assigned operational service volume. They are subject to line−of−sight restrictions, and the range varies proportionally to the altitude of the receiving equipment.
Most VORs can be used for voice transmission on the VOR frequency. VORs without voice capability are indicated by the letter «W» (without voice).
The only positive method of identifying a VOR is by its Morse Code identification or by the recorded automatic voice identification which is always indicated by use of the word «VOR» following the omnirange’s name. Reliance on determining the identification of an omnirange should never be placed on listening to voice transmissions by the Flight Service Station (FSS) (or approach control facility) involved.
Many FSSs remotely operate several omniranges with different names. In some cases, none of the VORs have the name of the «parent» FSS.
The effectiveness of the VOR depends upon proper use and adjustment of both ground and airborne equipment.

Very High Frequency (VHF) Omnidirectional Range (VOR)
The prefix «omni-» means all, and an omnidirectional range is a VHF radio transmitting ground station that projects straight line courses (radials) from the station in all directions.
From a top view, it can be visualized as being similar to the spokes from the hub of a wheel. The distance VOR radials are projected depends upon the power output of the transmitter.
The course or radials projected from the station are referenced to magnetic north. Therefore, a radial is defined as a line of magnetic bearing extending outward from the VOR station.
Radials are identified by numbers beginning with 001, which is 1° east of magnetic north, and progress in sequence through all the degrees of a circle until reaching 360. To aid in orientation, a compass rose reference to magnetic north is superimposed on aeronautical charts at the station location.
VOR ground stations transmit within a VHF frequency band of 108.0–117.95
MHz. Because the equipment is VHF, the signals transmitted are subject to line-of- sight restrictions.
Therefore, its range varies in direct proportion to the altitude of receiving equipment. Generally, the reception range of the signals at an altitude of 1,000 feet above ground level (AGL) is about 40 to 45 miles. This distance increases with altitude.

КОНТРОЛЬНАЯ РАБОТА № 5 (3)
1. Письменно переведите следующий текст. Английский текст перепишите на левой странице тетради, русский перевод− на правой.
The Traffic alert and Collision Avoidance System (or TCAS) is designed to reduce the incidence of mid-air collisions between aircraft. A mid-air collision is an aviation accident in which two or more aircraft come into contact during flight.
The TCAS monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder (an electronic device that produces a response when it receives a radio-frequency interrogation), independent of air traffic control, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of mid-air collision (MAC).
In modern glass cockpit aircraft, the TCAS display may be integrated in the Navigation Display (ND).
TCAS involves communication between all aircraft equipped with an appropriate transponder (provided the transponder is enabled and set up properly). Each TCAS-equipped aircraft «interrogates» all other aircraft in a determined range about their position (via the 1030 MHz radio frequency), and all other craft reply to other interrogations (via 1090 MHz). This interrogation-and-response cycle may occur several times per second.
Through this constant back-and-forth communication, the TCAS system builds a three-dimensional map of aircraft in the airspace, incorporating their bearing, altitude and range. Then it determines if a potential collision threat exists.
