उदाहरण वाक्य
- A low-power DME can be collocated with an ILS glide slope antenna installation where it provides an accurate distance to touchdown function, similar to that otherwise provided by ILS marker beacons.
- Some countries, such as Canada, have abandoned marker beacons completely, replacing the outer marker with a non-directional beacon ( NDB ); and, more recently, with GPS fixes.
- The EBL 1 operated between 30 and 33 MHz and received the azimuth signals from a transmitter at the far end of the runway, The EBL 2 operated at 38 MHz and received the two marker beacons as the aircraft approached the threshold to land.
- Apparently only the certainly expedient change of pilot and, consequently, instruments took place, which admittedly resulted in accurately flown turns and courses but still did not rely on the marker beacon emissions which were essential for an ILS in view of the atmospheric disturbances.
- A "'marker beacon "'is a particular type of VHF radio beacon used in aviation, usually in conjunction with an instrument landing system ( ILS ), to give pilots a means to determine position along an established route to a destination such as a runway.
- According to " Article 1.107 " of the International Telecommunication Union�s ( ITU ) ITU Radio Regulations ( RR ) a marker beacon is defined as " A transmitter in the aeronautical radionavigation service which radiates vertically a distinctive pattern for providing position information to aircraft ".
