Fast practice, instant feedback. Timer auto-submits when time’s up.
Avg score: 60% Most missed: “What does the term all weather landing refer?”
Landing Systems & Air-Traffic Management topics include: Landing mechanics, automatic and instrument landing systems, microwave landding system, air traffic control, satellite and carrier landing systems. An instrument landing system (ILS) is a precision guidance system that helps aircraft approach runways at night or in bad weather. It uses radio signals to provide vertical and horizontal guidance, including azimuth guidance from the localizer and vertical descent profile from the glideslope. The ILS sends information to the cockpit instruments so that the pilot can maintain a predetermined... Show more
