Il sistema è composto da un ils instrument landing system pdf di terra e da un apparato di bordo. Ogni apparato ha un particolare sistema di antenne radianti.
L’antenna di mezzo, posta tra i 3. Se entrambe le lancette sono perfettamente al centro, significa che l’aeromobile sta seguendo il corretto sentiero di discesa previsto. Questo dispositivo è usato per avvicinamenti con bassissima visibilità. 200 m ma non al disotto di 75 m.

An older aircraft without ILS receiver cannot take advantage of any ILS facilities at any runway, and much more importantly, the most modern aircraft have no use of their ILS instruments at runways which lack ILS facilities. In parts of Africa and Asia large airports may lack any kind of transmitting ILS system. Two signals are transmitted on one of 40 ILS channels. 90 Hz, the other at 150 Hz. These are transmitted from co-located antennas.
Each antenna transmits a narrow beam. S frequency which corresponds to the selected LOC frequency. S signal is in the 330 MHz range. Statements consisting only of original research should be removed. The glideslope scale is located to the right of the attitude sphere. On aircraft which have a mechanical gyro compass are both the localizer and glideslope indicated as a vertical and a horizontal arrow in the compass as well. But they are essentially read in the same way.
On some aircraft is only the glideslope indicated on two main instruments, and the oldest version of ILS-instruments was an instrument of its own used instead. This is, in theory, however, more difficult to learn—but even for pilots experienced with using such indicators, it added another instrument they needed to focus on. ILS frequency of that specific runway. If the transmitted localizer beam, which usually, but not always, is directed in the heading of the runway extension. If the aircraft is located on this line, the localizer dot will appear in the middle of the scale. In older cockpits, the localizer scale below the artificial horizon is rather short.
