CLOSE CATCH! Stunning A321 & A320 parallel approach into Frankfurt RWY 25C and 25R! [AirClips] HD

The main objective of implementing simultaneous operations on parallel or near-parallel runways is to increase runway capacity and aerodrome flexibility. The largest increase in overall capacity often includes the use of independent approaches to parallel or near-parallel runways. The safety of parallel runway operations in controlled airspace is affected by several factors such as the accuracy and use of the associated radar monitoring system, the effectiveness of the process of controller intervention when an aircraft deviates from the correct ILS localiser or RNAV course and the precision with which aircraft can and do fly the approach. In ATC terms, the various modes of operation available for the use of parallel or near-parallel instrument runways are distinguished as: Simultaneous parallel approaches Mode 1, independent parallel approaches: simultaneous approaches to parallel instrument runways where radar separation minima are not prescribed between aircraft using adjacent ILS; and Mode 2, dependent parallel approaches: simultaneous approaches to parallel instrument runways where radar separation minima between aircraft using adjacent ILS are prescribed.
