Контрольная работа № 5 (1)

1. Письменно переведите следующий текст. Английский текст перепишите на левой странице тетради, русский перевод – направой.

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 receivingequipment.

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.
